Your “Earth” “ground” or “negative” attached to the gearbox of the engine may not be a good idea. You said a path “through the prop shaft” is a really bad idea. I’m hoping you have a heavy ground strap to somehow supply a negative path from the batteries. Your engine is isolated from the steel hull by the engine mounts. The prop shaft could only supply current though a possible bushing bearing or a component that also provided ground.
So where would you put the ground?
For reference, this is the article I was reading.www.westmarine.com/WestAdvisor/Marine-Grounding-Systems It definitely seems like there is a lot of potential to get this stuff wrong so happy for any suggestions.
The batteries are the best. I don’t know how you have the your ground routed from your batteries. The shortest path with the biggest conductor is usually the best.
Sorry, more questions / info as I do want to understand this much better. So is the negative for the starter sufficient as the negative path from the batteries or do I need something dedicated as a ground strap?
The heavy ground on the inverter is mainly for the DC side, to trip the DC breaker/fuse if a internal fault occurs. Run it straight to the NEG Bar, I think you will find the coupler on the shaft isolates the engine electrically from the shaft. boats with a coupler like that use a shaft brush or strap to electrically link the shaft to the bonding system, there should be only one point of contact from DC neg to hull.
Hey Stu, pro tip from an aging ex-surveyor/4WDer (and your EPIRB donater ;)) best mounting your fire extinguisher horizontal as it prevents the powder from compacting. The motion of the ocean will keep the powder loose when horizontal or tap the bottom of the extinguisher with a rubber mallet periodically. Nice job "Danger Stu".
Nice idea. I have heard about the powder compacting on boats and we always used to advice people to turn them upsidedown periodically but a sideways mount does make sense.
Thanks for all the great videos! I love watching the warm summer arriving down there. Here in Norway the winter is setting in, and i just put my boat in for the winter. Your videos will help me get through the long dark period up here at the arctic circle!
Glad you like them!
I always thought Eddie was your dog, but it was good to see him again anyway. Thank you
On many large ships they maintain an isolated electrical neutral from the steel hull. It reduces the potential of electrolysis and if one wire shorts to the hull the safety protection circuit will not operate thus maintaining operation of critical equipment. They then use an insulation meter to monitor for electrical short circuits to the hull. For anything over 3000 volts special protection and shutdown system are required.
Yes, an unbonded installation is a good thing, but requires lots and lots of testing to make sure it is perfect.
@@DangarMarine You want an electrically bonded metal hull but just not to electrical system. That includes 12vdc and 230vac. Marine starter motors should be electrically isolated from the engine block unlike a land vehicle. Even the temperture sensors should not use the block as a return path to the battery.
*Dief marine make insulation monitoring equipment*.
*Corrosion reduction*
All metal items should be all bonded where practical to keep equi-potential to eliminate electrolysis. Some boats run a copper bonding strip the length of the hull to make it easier to bond differant items such as pumps and water purifiers.
Large vessels use special equipment that puts a galvanic electrical current across the hull to reduce electrolysis corrosion.
*Many electrical boating codes for smaller craft require electrical systems to also earth to metal hull*
So bonded in the sense that 0v is the same as the hull potential but everything has it's own negative back to the batteries?
@@DangarMarine Yes that's correct. All metal items on a boat should be at the same electrical potential (0 volts. ie low ohms). Use a multimeter. You may have noticed that outboard motors have bonding wires on all the metal parts especally on moving parts.
Also two wires to every electrical item back to the battery. I believe its possible to buy electrically isolated starter motors for marine engines.
If practical Never use the hull or engine block as an electrical return on a boat.... I know it's more work, but it can be done.
(Dissimilar Metals & salt water = equals battery = corrosion. Note corrosion always occurs on the negative terminal.)
@Maurice Upton That is a Naval requirement, where maintaining equipment operation is a higher priority than personal safety, personal safety is maintained by a heavy ground strap to hull, to ensure potential touch voltage on a faulty piece of equipment is minimised, Boats must have the neutral and earth bonded at each power generation equipment. for inverter/chargers, the bond must be broken and then the charger uses the MEN at the shore or generator. This is a requirement for commercial and recreational boats.
The engine is isolated from the hull already so using engine block as battery ground is OK, (of course it needs a neg from block to battery NEG bar) I would only connect engine related accessories negs to the block. The main requirement on a steel hull is to not use the hull to return current to the battery,
The copper strip is for non-conductive hulls.
the system you are talking about is called an impressed current system, still uses anodes and is prohibitively expensive as it needs constant monitoring,
Glad to see your hand doing so well. You are really sorting out things to make life better aboard. Looking forward to more. Thank you for sharing your endeavors. 👍🇺🇸
Thanks so much! 😊
Thank you so much, Stu for your videos. Basically inspired me to do my best with what I have. Didn't have very much so my 3m x 3m garden shed came out really neat and tidy. My goal of getting the 4.3 m tinnie out on the water every weekend is getting closer and closer. I have gone from once every 6 months to an average of once a month. One day I might even catch edible fish. Now when I do a job it takes me no time at all and it is so easy to find whatever I need. I know that making the videos adds an incredible amount of complexity to telling a coherent story. I can't even explain to my wife of nearly 40 years why I need to do things the way that I do yet you seem to achieve it effortlessly for 4000 strangers. Thank you.
Thanks Brendan, glad to hear you've been getting out and enjoying your boat. :)
Like the Aussie “customs” of bringing some brewski’s when you visit!
A 6 pack is the ticket of entry to many a boat, workshop or BBQ
Perfect timing for this to pop up. Wife is out and I have the TV to myself! 👍🏻👊🏻
Perfect!
Man electronics is next on my list of stuff to tidy on my boat ha!
My favourite boat and consultant
A voltage regulator actually isn't strictly necessary to run the computer off of the battery 12V - it almost certainly has an internal power regulator that can handle a range of input voltages.. But it would be nice for peace of mind since the only way to know for sure is to rip it apart and look up the datasheet for the internal regulator
Hey Stu, you drove right next to me in Mouth of Hawkesbury today, I saw this blue boat - I was like is that Renko???- then saw the back.....I was the idiot in the black zodiac!!!
Hi! :)
Dang, Stu... these things are never long enough! As Carole Burnett used to say "seems we just get started, and before you know it, comes the time we have to say "so long"...
I'm always torn between leaving more footage in trying to avoid making them too slow and dull. Hopefully the underwater searches will have enough action to make them a bit longer without being dull. :)
Greetings from central Ohio USA. It is always enjoyable to watch your videos...even though i don’t understand half of what you’re doing! Thanks and stay safe and healthy my friend.
Nice job,Stu....the bridge looks really good !!!!!!
Thanks 👍
Dust bath looks like the height of luxury for D-squad😀
They do seem to enjoy it. :)
@@DangarMarine Have you thought of trying this?¿?
Hi Stu, a couple of suggestions for future searches. When we looked for Banana prawns, pre GPS we had poly floats which we melted a groove around the circumference. We had twine with chain weight tied then wrapped close to the depth we were searching on the float that we would deploy on the target This may help narrow your search area in future.
I am not sure how much chain is on the anchor but maybe a grapple would assist in locating the chain in the mud.
Interesting idea. I'm not sure about the chain length either but I definitely agree that grappling is worth a shot in the mud.
always a good day when the electrics you have just installed does not blow up in your face, lol been there got the T shirt.
I think we've all done it once or twice. ;)
Noticed as you were doing the sonar overlays that there's a resize option. Shrinking the gps numbers seems like a good plan if they are primarily to use on replay after a search, so less of the display is taken up when you're watching it live.
Yes, will do.
Love the comment. "Using a screwdriver to punch out because it annoys people more" 👍👍👍
Knocking off the jobs at a fair old rate now! Great stuff!
Thanks mate. :)
Buoy's in water show up with huge contrast on sidescan data, when they're between the surface and bottom you'll also be able to see a "shadow" of the buoy, when the target is above the bottom the shadow will be disconnected from the object on the data. They're great for locating underwater. BTW, looked like you could resize the overlay fields on the sidescan screen and probably make them a lot smaller. I had a quick look through the manuals but couldn't find anyway to export the sidescan data as a data file. May be in there somewhere, but if you can get them out as an actual file (xtf for example) you'll be able to use a viewer program to plot the targets and analyse the data (measure, see position, depth data etc).
Hi Haider, it would be great to export the actual data rather than only having a video recording of the session. If the Axiom can't do that I might put in a feature request, you never know your luck! :)
Dangar Marine on Lawrence you can change the size of overlays with the zoom function. It might work on the raymarine too.
All the electronic upgrades will be worth more than what you paid for Renko at some point but I like the fact that it will improve your salvage and exploration quests!
You did well switching on,,, never let the smoke out or it won`t work again.
Very familiar sound of the Detroit under load ...good job
It looks on video that there’s more wire onboard then the Italian navy has spaghetti ! Lol. It looks like your getting more comfortable operating your vessel then before , good for you !
By attaching the ground to the gear box is that allowing an electrical path through a roller bearing.
Ah, I see what you are saying now. It seems that the AC ground shouldn't have a path into the water anyway so I'm going to switch it to battery negative.
Love your boat tinkering vids stu. I’m a bit of a tinkerer myself!
Glad you like them!
some really handy upgrades👍👍. We have winds here but autumn starting not spring.🤦♂️👍
Barefoot walking on a rusty ship wreck. You beast.
In some ways I feel safer. The only times I have every slipped over and fallen have been while wearing shoes and not having the grip and feeling that bear feel give you.
Well, you won't get tetanus if you inoculate yourself regularly
I could barely watch... wetsuit boots with a tread or some plastic/rubber slip on type things good for swimming at stony river beaches or crossing shallow streams whilst hiking. A few bucks to save a fearsome injury...
That’s some good footage of the dirty D squad.
G'day Stu, why not make use of the old tap hole, you might need to make it a bit larger and fit a cable access plate like you find on office desks, gives you access without having to remove the cutting board ( and whatever is on it) cheers.
Planning to put a slim cabinet on the wall there so the holes will eventually get used.
This anchor must be made of gold or something 😁
It's more about the challenge / practice than the anchor itself in this case.
That Victron inverter really should have its own 24v supply fuse. A catastrophic failure with those big batteries would be reeeeeally bad!
It's fused right at the positive terminal of the battery.
Dangar Marine Perfect! Last thing any of us want to see is all your hard work ending with a barbecued Renko!!
ha! Im glad I am not the only one acting like a Dad every time I see you "WHAT!? NO SHOES OR GLOVES! WHAT WERE THINKING YOUNG MAN!" :) since I have been watching you and you have introduced me to other people working on boats I often freak out about how often everyone says "well, time to drill some more holes into the side of the boat!" in my mind no holes in a boat is very important! I have a solo canoe and I was looking at putting a snap on cover on it and the second I saw the guy pull out a drill I was like "NOPE". I guess I just dont have the nautical courage needed. though I saw your friend on his barge with the crane on it come and get your table and to me it looked like his entire boat was ontop of deck floats? there is a guy in oregon who build his houseboat using them. I thought, how great is that? anything goes wrong with one of them and I can just unhook it and attach another. Im thinking thats means something like that has to stick to pretty calm water and no long trips but for a boat that doesnt plan on going far away on a river it seems like an ideal house boat platform. what do you think?
For calm waters, a platform build on floats are a great way to go. Plenty of catamaran-style BBQ boats like that on the river.
@@DangarMarine Thanks
Great video, Stu! Keep them coming!! EDDIE...❤️❤️❤️❤️❤️❤️!!!!!
Thank you! Will do!
That face and cluck said "It was Daffy. She made me do it. She said it would be OK. Thank God you saved me."
Great job bro 👍🏾
Thanks mate!
Stu excellent safety tips always bring beer. Progress is being made, looking good. Jeff in LA USA
Thanks 👍
Hi Stu, great vid, you can find 12v DC outlets and then cut the cigarrett plugs and install a 3 prong or 2 and into the dc outlet. way better
For sure, cutting them off is very tempting.
I have a small longnosed pair of vice grips for holding things I can't hold myself, it is called Apprentice and has been my best friend for more than thirty years.
They are handy like that for sure!
D-Squad are very very adorable.
They are. :)
13:59 wow didn't know that existed. Might have to take jetski for a look next time I am in the river.
Know it's for testing purposes but drag a few neodymium magnets for the anchor chain. It could be deep in that quality hawkes mud. Magnet fishing you won't find gold but they love ferrous metal.
I was thinking about it, but I'm not sure how well the magnets will pick up the stainless.
One thing to keep in mind when adding screens is how much extra light is produced which can really mess you up in the night
Yes, I wouldn't do a scan at night, you wouldn't be able to see a thing. The Raymarine has a great dimming feature though for navigating during a night voyage.
Nice update! Thanks!
Thanks for watching!
Leon is feeling pretty good about himself this week.
Those cig sockes and plugs are nasty. Swap them for merit/hella plugs as you get the chance. They are smaller for one thing and electrically sound. Love the Victron stuff.
They are. I think I'll keep the sockets so I can use random things that have the plugs on them, but other things that will be living on the boat may as well be cut and hard wired.
Perfect timing on a Saturday night 👍👌
Enjoy!
Dangar Marine it’s looking brilliant now stu!
You must be really pleased with it considering how far you’ve come!
slowly but surely getting all those annoying little jobs done which take the most time.
When do you plan on painting the deck area / cabin etc?
That will really finish it off.
The Vines is a beautiful spot - I've caught a few fish up there too. Hopefully this wind will bugger off today and next week is looking pretty good according to the forecast.
Renko is coming along well and I quite like the 'odd jobs' videos :-)
Thanks Iain, wind seems to be gone this morning fortunately but coming back in the afternoon I believe.
Strong winds from the north coming in today by looks and radar is looking heavy for radio and possible storms coming from the west. Be a good avo to be off the water I think.
I somehow end up with the same MPPT controller as you for my camping setup though need better panels for that setup.
Cigsockets are universal. That come from the obvious reason for them to be in all cars in the 80s to 90s when the use trends started changing. The power source was already there and everyone just used it because of that.
I think it's a little late for this suggestion but I installed mt 19" touchscreen down below the throttles rather than up above my head. There is less craning my neck to watch display and less eye strain looking down. It's also less bright (sun light) looking down and within easy reach which is important in rough seas.
That would depend on the boat, Renko is small enough that having a screen below the throttle would have it hitting your knees when underway.
Yes, unfortunately this is very boat dependent. I have my phone down low but it's harder to see than the little screen up high.
Renko's come a long ways, baby!
Thanks mate.
Stu, have you thought about putting covers over your computer screens when not in use ? They really do not like the effect salt air can have on them. .
Some covers would be a good thing. Not so worried about the cheapy LCD screen, but one for the computer would be good.
Hi Stu, nice improvements! And surely will continue, when installing the outdoor usb I thought why not also a 12v beside it for things like electric fishing reels etc
Could definitely use that other old tap hole for a 12v socket. Would be a good way to block it up too. :)
G'day Stu good segment still don't really understand the solar and electrics, it's great to see the improvements your making to Renko. Good to see mate and good to see the girls John
Thanks mate!
Nice to get all those jobs done.
It sure is.
@3:24 don't forget you can resize the overlays as you don't really need them giant size blocking 20% of the screen. @12:20.. where you put in the waterproof USB. i would imagine that it draws power when ever it is hooked up and switched on. just some thoughts..
Yes, will experiment with shrinking the overlays down a bit. There are quite a few things on the boat now that have a small constant draw but the solar seems to keep up nicely. There is always the main house switch to shut everything down though if needed, or just pulling indiviual fuses.
...LOOKIN' GOOD, NICE JOB...STAY SAFE..
Send an oil sample to a lab. They’ll show you if there is coolant and excessive fuel in the oil (from stuck rings) and such.
Ask a local dealership marine or heavy duty diesel who they use. They aren’t to expensive. And it cheap insurance.
Would be interesting to see what the results are.
hi Stu. there is a product called aussi duct(Bunnings or elec wholesaler) to hide your wiring. it has a square profile and lid which can be accessed easily for upgrades.
Walking a rusty old wreck with no shoes on !! What could possibly go wrong 😬
The worst thing would be a horrific bloody bath of an accident without the GoPro running. ;)
It is great to see you have got everything sorted and working now! Good Job:)
Thanks!
Don't forget to look out the window once in a while. haha
Love the videos keep up the great work
Thanks! Will do!
A little bit of dialectic grease on usb will help keep them in good working order
Stu
Could you go magnet fishing around the areas marked on the GPS. Might just hook up on the chain. Gotta love the dirt bath of D Squad. Keep lil critters at bay.🐜🐜🦟🦟🐞
I think the chain might be stainless so unfortunately a magnet won't pick it up. A grapple would though.
You can buy 90 degree hdmi adapters to clean up the cabling.
What happens if you pinch the screen on the raymarine? Does the GPS numbers get smaller? Can't really tell from the video but seems that not only the position but the size is configurable
Try not to run power wire along any for signal, like your GPS
Good point.
"And mind me platypus duck, Bill

Perhaps there is a lost verse about chickens ( - : A bit off topic I know except for the trailing credits
I'm sure we could write one. :)
@@DangarMarine All I can think of is 2 lines so far:
"Chicken Courdon Bleu Stu,
Chicken Courdon bleu..."
And before you flame me into eternity "courdon bleu" means blue ribbon, not squab flambé ( - :
Just a thought. Direct connection of screen etc to the boat's 12V system may be too much for them when the alternator and/or solar charge the batteries at more than 12V.
Hardly, most 12v electronics can take a wide margin of error. Generally they can take anything from 9-16v and just use a linear converter to dump the excess voltage into heat.
Hey Stu, that transformer very likely has a voltage regulator in it as well. If you cut it and tie it into your boat 12v, make sure you have an extremely clean and stable 12v line. Any spikes you get will gradually, if not catastrophically kill your digital electronics. Same philosophy as charging your cell phone in your car - it prematurely kills your battery because it can't handle the voltage fluctuations. So, the more regulation and filtration, the better. Cheers!
Yep, definitely agree. Have a voltage stabiliser on its way. :)
Another great video from my favorite YT host. :) Thanks for the great videos you make.
Glad you like them!
Good improvement!
My pieve is those wires that are not neatly tucked! Make it attractive in addition to functional!
Peave!
Good work, boat is looking outstanding.
Thanks Willie! 👍
Hello from Vancouver island your the man stu thanks for awesome build I have almost watched every video you have and gotten great info for working on my boats
Awesome thank you!
@@Islandwaterjet Have you checked for owner listed boats on Cragslist? nearly 3000 listing for BC in that section.
Even a couple of Hourstons, glasply and bayliners under 32 feet.
@@Islandwaterjet yup I know the price needs to be right.
I think the biggest drawback is the size.
While there are a lot of listings in the under 35 foot sort, they are filled with jetskis, kayaks and canoes.
Been waiting 7 days for this
me also :D
Is there a church on Danger Island? And does everyone go barefoot? With a six pack? Take care, enjoy it properly, please keep making vids.
No church, but barefoot with a six pack is the national outfit. ;)
Awesome as always Stu,I am almost sure yiou can alter the size of the overlays on the Raymarine if your eyes can handle a smaller size,take care and stay safe
Thanks David, I'll have a go at tweaking the font size today.
You can hit Man Over Board MOB button on your Raymarine plotter when you want to store and hold a position.
You can.
Yeah!! No smoke!!!
Always a win! ;)
Your side is 240v but state side here is 120v but on major stuff it is 240v.... Thanks mate....!
It's time for treasure hunting mate!
Too right! :)
We just turned into fall here on the Eastern part of the states..Va.is were I am from..
Ah, summer never lasts forver unfortunately...
@@DangarMarine I look forward to fall,I like cooler weather, our winter's aren't that bad here but we do get some snow in the winter..
Can get some really nice kitchen pods
cool beans!
I think you could do a nice side hustle surveying the seabed to update the known bathymetry with recent observations using your sonar setup. Consider this free advice (you've probably already thought about it) but I am a geophysicist by training so if you're interested to collaborate drop me a DM
I've noticed that Navionics does have a built in feature to record your soundings and allow you to share them with them to make future map updates more accurate. It's a great form of crowdsourcing.
You can buy 90 degree HDMI plugs to solve this problem
Hi what about putting that app for the sounder on the computer so if you want you can have a window display on the screen Infront of you so you don't look to the side as much. You can also have a external SSD or USB on the computer so you can record to the instead of the phone. You might be able to check footage at the cabin computer or even do editing onboard.
On the day, it is mostly about driving the lines needed to cover the search area. Although I do look at the sonar at the time, it's very easy to miss things while you are driving so I'm going to try to get in the habit of not worrying too much about analysing the sonar scan until after the boat is back on it's mooring. Recording straight to SSD would be good though, although AirDrop onto the laptop does work really well.
What is the open pipe next to the air intake at 18.57 ??? And what does it do and why have a flap on it.
I think I know what it is but just not sure.
It's the oil filler cap, wired open to relieve crankcase pressure until the stuck ring is fixed.
Dangar Marine , thanks very much for the information.
what gauge is that multi-core, I want to run one multi-core to the back of my skiff, should it be 14 gauge for a 20' run?
Hi Stu,
Was wondering if you would be interested in having a fan meet up at a Gold Coast boat show in November.
Wwas thinking of getting a few bloggers together. Maybe Brupegs as well.
Let me know your thoughts.

Motor Sailing For Old Dudes
Hey dangar or local community to central coast/hawksbury are there any places I can slip a yacht to clean and antifoul myself over a weekend
Fewnwicks Marina will let you antifoul your own boat.
I almost certainly lack your knowledge and understanding of electronics Stu, but feel compelled to ask whether you have ascertained that the 12v transformer does not also serve as a filter and provide other protections for your hardware?
As I understand it most computer hardware actually operates on voltages far lower than twelve from motherboard level on.
Yes, if I go direct DC I'll probably need to add some sort of simple voltage regulator.
Hi, not sure where to ask a question so am putting it here! Have a 1995 Mariner 150hp. Starts good but no water tail, beeps continuously after running for a few minutes so am assuming the impeller is faulty. Is this a correct diagnosis? Am in the process of taking the lower leg off but the bolt at the rear is stuck and I will buy a gas burner today to heat it a little before trying again. Any help is much appreciated. Keep up the good work! Thx
Hi Stu! Great video as always!
Is there a law in Australia against marking the chain (or whatever you might find) with a boue above the surface? Just as you would mark any net or other fishing-gear... Does it have to do with tide and/or current maybe?
Cheers
No, you can definitely mark it with a buoy, it just depends how long it will be before you get back to it. If it is on the surface for a long time there is a good chance that someone will run over it at night and you'll lose the position.
@@DangarMarine Thanks for quick response and flawless spelling :-)
Stu, are those prescription safety glasses you're wearing while working on the inverter? If so where did you get them, I live in Sydney.
I've been meaning to get some but my optometrist couldn't get any.
Yep. I just bought them at the local Hardware and General store. I forgot my reading glasses so I'm glad they were on board!
Any update Stu on the motor ‘stuck ring’ issue?
Not yet, I keep forgetting to give Adrian a call. Next week!
