- In this video I tune an outboard to stop it stalling and idle. This mostly involves setting the idle mixture screw and idle speed screw.

Mr danger is my go to for how to videos.
Thank you for being so detailed but yet understandable.
Obviously a man of good taste, enjoying a Cooper’s Pale Ale while he works..
It's very therapeutic sitting at work, watching Stu working and explaining. Almost feels like I'm there doing it with him.
Thanks Nick. I always feel like I'm hanging out with you guys while making the vids too. :)
Great info Stu. Premix at the pump, that's awesome. Wish we had that in the states.
It is very handy for the commuter boats. Travelling back and forth each day we tend to fill boats up once a week so mixing fuel becoming tiresome.
unless you are using the boat every day, premix can work against you. it will settle and separate after a few weeks, needs to be mixed again.
"well thanks for watching" 4 minutes before the video ends HAHAHAA good on ya Stu ur a legend.
really good point from 12:00 on, take note people, thanks Dangar
Wow, have not seen an HP calculator in a long time.
RPN for the win.
Indeed!
Yep. I saw the calculator and trawled through the comments to see if it was just me who was old school.
Ciao.

Always impressed with your high-wire performances, working on outboards while they're hanging over the water...
Eddie...... Ruf Ruf.....YOU, Dangar Marine.... are outboard magicians.... can smell the air of fuel droplets and decide on the right direction to modify.... Cool stuff Mate.
Stu, Good to see the content coming…. I haven’t owned a boat since my early teens but at 57 I’m still interested to learn something that I don’t need or Will ever put into practice…..great stuff mate.
Thanks mate, glad you enjoyed it. :)
Get yourself a boat mate. It’s not too late
@@kiwiwifi here to say the same.
He needs to get himself one.
Im 39 with 4 kids and made it happen.
Nothing wrong with mine, just love dangar
Get that boat brother!
@@DangarMarine hello Sir really need to speak with you if possible about my Johnson ocean pro. Sorry not sure this is the best way to contact you I will keep trying
Glad to see you back on outboards....
Thanks mate, I actually enjoyed making this more than any other video in a while.
Greetings from Denmark-You are a Master.........GBY......
Hello! :)
White Ants. Plenty of those mongrels on Dangar. About 45 years ago my old man (a builder) rebuilt a house on Dangar after it was devastated by termites. Keep up the vigil Daffy!
Love to see you using an old HP calculator! Reverse Polish notation ftw!
I do love the HP calculators. :)
@@DangarMarine I lost my handheld from college but have an HP app on my computer. I still get confused when I use a normal calculator. Great content, man. Keep it up!
Love these outboard videos. I had the same problem with my 2003 Yamaha 115 4 stroke. Three trips to a good marina couldn't solve it. I finally swapped out the IAC valve. It cost $40, took five minutes to swap, and fixed the issue of stalling at low idle.
Nice work!
The fact that your dock had pre-mix at the pump, blew my mind! Land locked here in Colorado (US) and have to mix all my fuel.
im working on a 1981 9.9 evinrude for a friend, i cleaned the carb but it was way out of adjustment, its evident that someone worked on it and couldnt figure it out then just left it, parts missing and all, well i got it running but am facing the exact issues demonstrated here, thank for the video it will be a tremendous help when i get back to it in a few days.
other thing im trying to figure out is the tiller is a shaft driven system and when you rotate the handle the shaft going into the outboard seems to have slop in the teeth or something and doesnt want to engage the carb like it should....anyways, Cheers from Tulsa, i met you at the SV Seeker meetup and it was a pleasure to have met you, good to see it looks like you are doing well as well
Hey Stu, I miss this type of content please make more. Love all that you do.
Thanks mate, will do!
As a new boat owner, with a very old 1985 Johnson 100 hp two cycle outboard, I have found your videos very informative and easy to understand, even if the fix requires more skill that I currently have. Thank you very much and keep them coming as I love learning!!!!
Glad to help. Enjoy your new boat! :)
Hello Stu, St. Catharines Canada here. Just found your YTube site. Watched the first bit, , , ehh , , maybe later. I don't own a boat anymore. Old age pension is to tiny. BUT ! Then I heard " Thinking Juice " ! ! You got a new subscriber brother.
Welcome aboard!
"Grab some thinking juice" pissed mysrlf 😅😅😅😅😂😂😂😂
I've never owned a boat in my life but I love wtaching your channel!
Thanks Ian, glad you enjoyed!
Wow premix at the pump! I’m this day old to find that out. Clearly been under a rock
Videos like this are why I started watching you. Thanks Stu.
Glad you like them!
Happy to see your doing some outboard instructions again!
Great clarity in explanation
Good confirmation from you on my thinking that my Mercury runs better with the choke somewhat halfway pushed in.
Love these videos, extremely educational!
Hi Stu, been watching your channel for several years now. You’ve given me the ambition to fix a 2000 merc 25 2-stroke that has been non running since 2014. Ive replaced everything in the ignition system sans the coils but all she does is back fire, its been a head scratcher. I’ll be looking through more of your videos for additional guidance. Hoping she doesn’t end up as a hung cowl in my garage.
If it backfires it either most likely either bad timing or the coil leads going to the wrong spark plugs.
@@DangarMarine That was it had crossed leads. She fired right up… thank you very much!
Awesome basic troubleshooting instruction video. Thanks Stu!
wow.. wonderful.. glad we got a new video on outboard servicing!
Awesome Stu, just saw this. Going to bed soon so will watch it tomorrow. Tim
This vid came as if ordered. I am having this exact issue on a 40 Suzuki , have a much better understanding now to sort it out.
I enjoy watching all the advertisements before each video as I know this will bring more quality videos in the future :)
Thanks mate!
You forgot to mention, when discussing old fuel, that gasoline with ethanol added, is Hrdroscopic: that is it attracts water. So, sitting, it will end up with water in the float bowl, and that can cause all kinds of issues. Lawn mowing season just started here, and I have to go thru all my engines (carboraturs) that weren't properly put away. I try and run "seasonal" equipment dry... I've been adding fuel shut off's to machines that don't have them vs having to run the entire tank of fuel out :) And run ethanaol free fuel if possible!!!
you are doing the correct things. And finding a no ethanol gasoline for your garden tools or boat engines is way up there. The 'run 'til its dry' method is the best too.... any left over fuel that you can't got rid of, put it into your car........ it will be OK. But to leave it in your boat motor or chainsaw...... it's gunna get blocked for sure.
Thank you for all of the videos, you have saved me a lot of headaches and money as well.
Great video Stu, greatly appreciate your efforts in making these, inspires me to have a go and work on my own old boats. Even my Border Collie is now a keen watcher of your videos. He was glued to the TV watching the chickens and parrot at the end of this video and didn’t move and continued to watch as an older video of yours started up.
Great basics Stu, thanks for posting.
Any time!
Great stuff Stu. Never really understood the why of tuning. Thanks!!
Great video. I learned a few things. Cheers from Canada!
Great diagnosis Stu, great Video.
Thanks Wayne!
This is the type of video that originally brought me to your channel.m This type of content is some of my favourite because I can relate to it more. Going to to the garage (shed) now to work on my 1964 Honda C200 with new knowledge! Be well.
Glad you enjoyed!
Good info. Happy cruising.
Thanks mate, you too!
I love the reasoned detached logic behind your troubleshooting. And I'm mindful of the legal maxim: "A man who represents himself has a fool for a client." As a 'boat owner' (sail, and power boats.) I find myself too 'emotionally involved' when things go "South" Instead of thinking logically I think emotionally, and in a accusatory way. I recriminate with the inanimate object (Frikkin' bast@rd motor that will not go) Now at age 70 I find it easier to drag the malingering motor off to a detached professional to resolve the problem, sans swear words tears and hammer blows. Love your work BTW
I was discussing a similar thing recently with a friend. I find it much easier to see problems that other people are facing as easily fixed due to the emotional detachment.
Great video Stu. Thank you.
Very welcome!
Im not sure how i found your channel stu but so happy i did your a propper man !
I love your videos mate! Thank you for sharing your knowledge. Good production too!
My pleasure!
You're a good fella, take care.
Beautiful day on the hawkesbury 👌 Daisy showing who's boss haha
Those insides look just like my 2 stroke 8hp Yamaha. Lol. I always appreciate your videos! Nice to see you and hope all is well in your little part of the world.
Thanks, you too!
Top work as ever Stu!
Thanks James!
In the end, I had many other problems with my motor which was not the external tank. After seven visits to my local Boat shop, I decided to get a second opinion from a Commercial boat shop that also worked on small engines. After a few minutes and after conducting a compression test on the motor they immediately concluded that the motors compression was way too low. Yup, a brand-new motor. After trying to figure this out for over a year and various visits to my local boat shop my conclusion is get a second opinion by another professional. It never hurts. Thanks for your video and help.
Thanks, nice to see someone following a bit of logic and not just firing the parts cannon at the problem :-)
Thanks Rob. I've always been a big believer confirming a part is bad before replacing it. Service manuals are great for that as they will almost always give you acceptable ranges for testing parts.
Please do more content on some of those basics. Love it!
I definitely will. I was talking to Adrian yesterday about how easy it is forget that many people are new to engines and miss out of explaining some of the prerequisite stuff. Will definitely be getting back to basics more.
Love these 2 stroke small outboard videos ,this is what i stumbled upon awhile back and subscribed to you channel
Thanks mate, glad you enjoy them. :)
An HP 35 scientific calculator, you’ve had that a while, I believe no longer available. One of the best calculators in my opinion ever made.
I do love the HP calculators! :)
I find your videos continuously useful and rich. Keep up the good work, it's much appreciated!
Glad you like them!
Hey Stu, what a perfect day for messing around with boats. That water was nearly like glass. Not bad for a near mid winter day close to Sydney. Ya wouldn't be dead for quids mate. Good content, well explained and common sense narration. Well done mate and thanks for the effort. Greatly appreciated.
Thanks Bruce. It was a very calm day on the water for sure.
Great video, covered many of the basics of fuel air delivery and mixture. Very informative!
Glad it was helpful!
Thanks Stu, great info.
Very welcome!
Thank you for doing these videos...really helpful!
Happy to help!
Your videos saved me a ton. Replaced starter On Evinrude 175 out board successfully !! Thanks
I’m was wondering why I find your videos so comforting and I think it’s because you describe things as they really are.
There’s no BS like one always gets when dealing with service managers in car dealerships.
It’s like having boy’s fun working on an engine with a straight talking mate.
...just a bit of fine tuning, good job, keep safe,,
really enjoy this type of content, it's why I started watching the channel before Renko came along, which was bonus material!!
Glad you enjoy it!
Stu is my go to guy if issues with outboards keep it up Stu brilliantly explained Thanks you
Mate, love these videos. You of all people have helped me the most sorting out my own little 2stroke yammy. So many little details in the video that are super super helpful. Love it, and thank you!
Great to hear!
Small combustion engines are pretty much the same. I had a pressure washer motor that would start, run for about 30 to 45 secs....then die. A neighbor told me about Techron. He said go pick some up at an auto store, pour a little (key...little) in the gas and give it a try. Did the trick. Now it runs like brand new and that is all I did. Worth trying before a simple or complicated tear down.
Great information
Saw a peak of Red Dwarf 2! Hope she’s going well!!
She is, thank you Matt! :)
I like the small engine stuff. Thanks.
Good one. I always have trouble with carbs.
Stay safe Stu. Cheers Mal in SA.
Stu you are such a good teacher. Love how you show and explain everything in a humble and simple show-and-tell way. You come across humble yet it's also clear you are a fantastic mechanic and a real specialist.
Wow, thanks!
Very interesting vlog Stu👍
"Thinking juice" ... Ha ! Great chuckle !
Glad to see ya back in the saddle. I'm looking forward to more with you and Adrian working on that "new" boat. Being a long-term user of of HP products, I was happy to see you RPN'ing with that calculator.
I do love the HP calculators! :)
Your outboard repairs have improved since the one you fixed up in Qld🙂
The HP calc brought back some memories
Mad Max?
Best marine Channel hands down fkrs
Man I love your vids. Had the same problem with my car. Obviously a fuel injected 4 stroke, so totally different engine, but it was an idle air control sensor causing the problem. I like the simplicity of the adjustment screw on the 2 stroke! Anyway, besides learning about troubleshooting marine engines I like to see the differences in engines. Thanks for making these.
I've got Yamaha 2 stroke 200hp outboard. I live in Florida and I've noticed I need to adjust the carbs depending on the outdoor temp. When it's cold outside it seems to idle higher than when it's summer and 92 degrees out. I've also learned when tuning the carbs, run it in a barrel under pressure, not on the ear muffs.
It is amazing how much the subtle things like temp and water pressure can affect how it runs and idles.
Great video. I enjoyed how you addressed a problem by exploring how the motor and carburetor are supposed to work and then looked at simple solutions first. Digging into a carburetor ups the chance of a maintenance induced failure and a real time burner, all the while the motor works fine.
Very informative video. Thanks.
You're welcome, glad you enjoyed it.
I always set idle speed by ear. Works every time and is quite accurate.
Excellent advice on thinking about "what's changed?" if anything.
Great detail and explanations along the way without turning it into a boring lecture session! I've struggled with the carburetors on two strokes, this helps.
Thanks Jeff, glad you found the video helpful.
Hi Stu, just watched and must say good to see you going over the basics on small 2 stroke motors. Allot of folks don't know much about these. Things like having the pump ball point with the arrow up. There is a check valve in it and once full insures there is no air in the line. Different fuel/oil mix requirements like 50:1, 24:1 and for the vintage 40's motors 16:1. Having the owners manual and a service manual if your doing more than the basics is a must. Good to see you doing these videos. Tim
Thanks Tim!
Thanks for sharing
Nice video Stu, good to refresh what you think you know but often forget....plus went online and got myself one of those handy gap gauges.
Glad you like it. Those gap tools are such a great, cheap thing to have in the bag.
Perfect timing with this video! I've got a motor that is stalling when going into gear, I'll definitely be using this video as a guide for solving that issue. Thanks for the great content!
Good luck with the fix. Another common cause will be a dirty carburettor.
Another great video, thank you!!
My pleasure!
Great video, love your style.
I have worked on carbs for years, just tinkering. My 2 rules of thumb...
1. If the idle mixture screw is located on the engine side of the throttle plate, it's fuel adjustment. If it's located on the air intake side, it's
air mixture.
2. When adjusting the fuel mixture screw, don't aim for the highes idle. That's too lean and not good, especially for a 2 stroke. Set it at a start
of 1,5 to 2 turns out (warm motor) and find a decent idle speed. Now, turn ut in 'til revs climb, (lean) and make a note of screw position.
Now turn it out slowly 'til the motor just begins to run slightly unevenly. Split the difference of those 2 points and that's the
stoechiometric ratio for that motor at idle.
Cheers.
once I've found the mixture screw adjustment......... I just do the screw turn counting between too lean and too rich....do your arithmetic and wind the screw in between these points; and who cares if you reach a stoechiometric balance ?? Just get the freakin' mixture to work well; with intelligent use of the idle screw....
if you get into
stoechiometric theories and practice, you are going to need a lab on board to take real readings.... and at least a chemist as a staff member
hello, your videos are very good, I've learned a lot from them even without understanding their language because I'm Brazilian and I have an old evinrude 135
hello good morning
Glad you like them!
Vintage Dangar Stu! This kind of stuff is how I originally came to be a subscriber. Loved all the work on Renko, but I relate much better to outboard work. Will watch whatever boat-y content you publish though. Oh, and D-Squad content too! 😁
Have a 90 model Johnson 8 HP behaving exactly the same way, went through the same steps and now it idles correctly and its as good as a 22 year old motor can be, thanks once again for a first -class informative video. You keep us all running smoothly.
I haven't followed your channel daily since the very early days, but still have taken a peek now and again. Although I've enjoyed your adventures in the larger scale, the kind of vids like this one are the vids that I always enjoy the most.
You know the kind. The kind of video where everyone can tell you a better way to do what you do, an easier way to do the exact same thing or tell you that you know nothing. Afterall, the internet is the internet.
You're a gentleman, my friend. I always enjoy watching.
Thanks Rob, appreciate you stopping by. :)
Great video
Looking forward to this video series. I have a 5 horsepower outboard my grandfather bought in the 70s that I've been meaning to rebuild for a sailboat project. I'm sure this info will prove useful, so thanks! 👍️ And props for the reverse-polish HP calculator!
Thanks Ted, good luck with the sailboat project.
Thank you for this video. Having a similar issue with a '71 Johnson 60hp. I think the carbs (all three) need a good cleaning. BTW, every time I or my wife wears out Dangar Marine t-shirts, we always get compliments...and you potentially get new viewers!
Thanks mate, glad you enjoyed the video and thanks for supporting the channel! :)
