The best boat is one owned by a friend.
Exactly! BOAT stands for Bring Out Another Thousand. And they're a ton of work to maintain. I have enough chores and projects to keep myself busy 😬
@@WaldosWorld A boat is a hole in the water you keep throwing money into.
The best pool is one owned by a friend. 😆
i love watching the work you do,thanks!
@@WaldosWorld what ....no pirates of the Caribbean references?
You could have mustered at least a Capitan Jack Sparrow run
The best two days of boat ownership, the day you buy it and the day you sell it.
Really appreciate how you consolidated things and didn’t make a 5 part series over months.
This is the best in this channel
When welding to a broken bolt, it helps to weld a washer to the bolt first, than a nut on top of the washer.
Good tip!
I always worry that I'll weld the bolt to the material around it
Hi Samuel: Once in my life I had to have a broken bolt welded, and am pretty sure I'll have to do it again someday on some project or another. Why the washer? What function does it serve? Is the idea to isolate the broken bolt weld from the surrounding material?
Sounds like a good tip and I'd appreciate the reason behind it. Thanks.
@@freebuilder007 It is easier to weld the washer to the bolt because the washer is thinner. You can get better penetration into the bolt and you are less likely to weld the bolt to the surrounding material. Then you have a larger surface to weld the nut to, making it less likely to break off.
Great job buddy! 👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🙏🙏🙏🙏
Nice Cape Dory 36! Those old Perkins are great engines. Defiantly worth rebuilding rather than repowering the boat.
Welcome to the best life there is, Waldo. It might be your friends boat this time but it won't be long until the sickness sets in and you buy one yourself.
Catalina 22 in my future!
I don’t know how I missed this episode Waldo. Awesome job on resealing that engine! I’m sure your friend will have many years of leak free sailing!!
Right there with you, his video today was the first on my home page in months
You were smart changing all those gaskets and manifold studs ! Especially when they installed it back in that tiny space on the boat 👍👍👍
I didn't realize that sailboat's had engines. That one will probably last for the rest of it's life now ❤
Wow, I would have expected a boat of that size to have a much larger engine than that! Goes to show how much I know about boats.. almost nothing lol
I have worked on 4108 engines forever and this video covers everything and confirms that if it has a gasket replace it. Great video. Thanks.
Single best Perkins 4.108 tutorial video I’ve ever seen
This has been my favorite episode so far. Love learning about boats
Your quite the talented individual. A rare breed indeed. Just a tip, I saw you use a flathead to pop the oil pan. Ive found using a gasket scraper does a really good job of popping pans and not bending the pan as much as a flathead. I use snapon gasket scraper, and i grind the end just a little thinner to help get it started when popping a pan. Its work well
A leak free 4.107 or 4.108 is a rare thing to behold
Cliche.s about B O A T. , etc etc, this guy is a real pro!!! He formulates the plan, extracts the engine, then free unfettered access to all seals! He knows the little tricks, and the appropriate goop to use and where. That Perkins will be skippy for many years to come. ⛵️
Not always necessary but a skim coat of anaerobic sealer in the parting faces of the rear main seal housing is nice insurance to prevent leaks.
I do love these small Perkins diesel engines very reliable and simple.
True, wonderfull machines that can create their own engine oil.
Acronym for B.O.A.T. - BUST OUT ANOTHER THOUSAND
About 45 horse? I had a Volvo D1-30 three cylinder in my Ranger Tug. That one was 27 horse. I love the simplicity of pre DEF diesels.
From a hazy memory the 4.108's are fairly high revving (~4k rpm) hence the high horsepower from such a low displacement diesel. In fact, in the 60's they were used in various cars/vans/taxis in the UK - weren't many high speed diesels back then.
I love the simplicity of older diesels too but make no mistake, modern diesels make more power per cubic inch then the older ones.
Waldo, my hat is off to you sir! You are one talented man. 👍👍
Great video, doing this myself even after a full rebuild, that seal is picky. One important thing though: If you do not use the special alignment dowel on the Jabsco water pump for the timing case (Parts4Engines sells it) you WILL have a catastrophic break in the the timing case where the water pump mating shafts meet. The collar on the outside of the timing case is meant to be aligned with the tool then permanently fastened down. You can then take JUST the pump off to service it and leave the collar which is still aligned.
What a great video. You are truly an ace who really knows Perkins engines. Thank you so much for explaining and sharing your skills. I wish you were around San Francisco to work on my Perkins. Thanks again.
Great engines 4108 , very reliable , simple, done thousands of miles with these , thanks very interesting Waldo great everything went well !
Thanks Steve!
That was pretty painless, the crane is a game changer.
My Grand Father worked at the ship yard. Thanks for bringing back memories! Nice job!
This was awesome to watch ! Never thought about a crane taking the engine out . That’s cool.
Goose neck trailer build part 2!!!
Never seen that way to remove a broken stud before - very nice to know!
Nice job. Please do an update at the end of the season in the fall. Thanks and take care.
Another excellent and thorough repair Waldo 👍🏻🏴
My first thought when saw picture, Waldo striked a bargain auction again.
Great job, that crank looks like one from a Model T, I can’t believe it’s from the 80’s
Well done once again! Waldo is a friend that we all would like to have!
I started wanted your channel, and you are just a genius when it comes to welding,replacing parts,etc. I have no ideas to do the things…well done Waldo…stay safe,n watch your fingers n hands…hehehehe
I'm in the middle of restoring a 3.152 ... mostly fixing leaking oil is my aim, and a new lick of paint. I think rear seal is fine, but front seal is clearly spitting out oil. ... this is useful, thanks.
Once again waldo is the goat man cannot make a bad piece of content
I love your videos!! I can’t wait for more! This repair is def reminding me of the range 😭❤
Awesome as always.Thanks for sharing and taking us along
Well that's cool timing, I just went on a sailboat for the first time yesterday, much smaller than that one though. It just used a little 10hp outboard lol
I don't know anything about boats, but I'm watching this guy :)
I believe that new rear main seal is graphite impregnated, iirc. Great vid Waldo. When are you finishing up the gooseneck?
Best CZcams on Rear seal…..thx, and look forward to more of your videos.
agreed
You really need a big, flat, well li, ventilated , warm workshop Waldo
Well done! I had a 4.108 on my Islander Freeport 36. Your engine access was miles better than mine! I would have done a new rattle can paint job to be able to detect any leaks a bit easier. Since you had it out it wouldn’t have been that much more work. I also would have rebuilt the mechanical fuel pump since they are notorious for leaking into the block. Loved the 4.108 but hated trying to get parts for it
Pretty nice, it’s all about attitude and yours is great - heck you even seatested with the owner. Not many marine engineers would get there’re feets offshore. Respect, great attitude to doing it RIGHT and not skimping . 👍👍
Thanks for another very enjoyable video - very nice work with an excellent explanation of the processes involved.
Well done! Always look forward to your uploads!
Enjoyed your video very much, as I sit 6 feet from my 3500 hour 4.108 Perkins, on my sail boat, in NC. My Perkins rear main seal leaks some but not enough to pull the engine. Otherwise, no other leaks yet. If you wouldn't mind sharing, where did you get the injection pump rebuilt? The engine really sounded good when you launched. Thank you.
Awesome vid, just wish we got to see a bit more of that trailer
Good job there Mr W, glad you resealed it all.
Waldo, another amazing video! I could watch your videos all day.
Nice job 👏 great little engines
Thanks for the great videos! I'm actually learning marine diesels now.
Cheers Jeff
Nice video and repair of the motor. I enjoy your channel a lot!
🎥🌟👍 "Mr. Waldo has a unique talent for creating enjoyable videos about practically anything! His expertise and engaging style make even the most intricate tasks, like replacing a rear main seal on a sailboat, fascinating to watch. Can't wait for his next adventure! ⛵🔧🎬"
Everybody needs a Waldo friend your a good bloke mate really enjoy your channel so very varied content

Are you ever gonna finish your gooseneck Trailer? 😂
Yep, part 3 coming soon!
Excellent quality video. Thanks.
Nice work.
It's a dream of mine that someone with your skill and care could do this to my 1984 Yanmar 22. Unfortunately I live in Los Angeles so I'll just have to re-watch this video and dream about it.
Hi Waldo Mr cool guy 😎 Yeah loving your videos especially the attention to detail 👍🏻🏴
Your always getting into something 👍👍
Well brilliant!! My second love! Sailing and cars! Surprised you didn't rip out the Perkins donk and fit a 3-53!
That was a wonderful video I learned a lot on little diesel sailing engine man very cool
Cool project. Thanks for sharing. 💪👍🏼
I know a guy who welds a slightly oversized on the O.D. Washer to the bolt/stud. The excessive depth of the hole on the nut can cause the weld not to penetrate on the stud. With a washer you can get a good weld on the whole circumference of the hole. Then weld a nut to the washer. Again you get more weld lineal inches of weld this way.
Weld the nut on the outside to the washer.
This will allow much more torque without breaking. It seems this would be the standard practice.
Great job! Take care and I’ll see you on the next one…Waldo rides again sail boat style!!!
I prefer to remove the sump while the engine is still right side up to avoid rubbish falling into the works. Flip it for the refit.
Looks like a beautiful Cape Dory 36 -- a fine vessel.
Nice job, very thorough. I have a Westerbeke L25 and a 2000 series Volvo Penta I'm going to eventually sell. The Volvo is running well with no known issues but it should be gone through prior to selling it, and the L25 hasn't been run for a couple of years and likely needs some love beyond gaskets etc. they are both in NH so if you or anyone else close by is up for the job and want to go through them they are ready to go, and will be available if anyone needs either of them once they've been serviced.
I really enjoy your videos. Thanks
Very interesting, thanks! As a long-time sailor of small boats, I've had the chance to be under power by: Perkins, Volvo, Westerbeke, Kubota and other great little gas and diesel engines. Glad to see this one carefully worked on. Be well, be safe!
Hi from Milton New Hampshire. Time for a break and finding Waldo.
If anyone can make a boring job interesting...Waldo can!
Interesting and enjoyable....great content WW!
Thanks Waldo , l subscribe. However somehow didn’t
Get this one . Really enjoyed it. Incredible production quality.
Nice project. Good job.
Nice CD36 and good video of this engine. Cheers.
Dude!! I’ve always wanted a sailboat!!!!❤❤❤❤
Gooseneck build part 3 please
Nicely done video.
Your a really good friend...and great job
thank you Waldo
Interesting that you did not do much other cleaning to the engine while it was out. The pulleys had some visible rust in them. The block needed a quick bath on brake clean and steam. Oil filter should have new and the water impeller replaced since you had the pump open.
Looks to be a Cape Dory….30, cutter rigged. Fantastic boat!
The amount of gasket sealant you use kind of erks me, but you clearly have more experience than me maybe I am missing something. Nice video.
Beautiful job!! I ran my old, restored 50" Jubilee sailboat (Joel van Sant) with that same exact engine. Loved it! (the engine and your work)!!!!
I am once again asking for you to give us the goose neck trailer
Waldo. Have you considered using a military deuce and a half as the topic for a video? Seems like it would make for an interesting project.
I think that would be a fun project!
Another great video! Would love to know the music you used - it is outstanding. Thanks for all your great videos.
Get some razor blade sheers for cutting rope seals. Way easier to cut stuff accuratly. My Contenintal F163 motor for my 1978 Linclon SA200 uses rope seals like this Perkins. Great channel.
Where the cork meets your flat gasket, you always want to put a big bubble of RTV right in the corner, that's where it will most likely leak first. (8:05)
13:02 Use 312 stainless as your filler ….
Use acid to strip the zinc coating
Let the heat soak a little longer
Use some sort of impact gun to extract the broken bolt
Love those “white walls."
Such great video's I could watch you eating your breakfast and still be entertained (strange I know!). Stay safe.
Had a Perkins diesel in the last genset on my 40' MCI motorhome
A Waldo video, my weekend is complete. Dang, you can work on anything with an engine. Removing the engine looked difficult. Nice haircut. You still have snow on the ground in May?
you did good by replacing all the gaskets/seals at the same time while the motor was out
.....and the studs
Good info ! thanks
Waldo in my backyard! Nice work! The guys from Independent Boat Haulers are a hoot, aren't they?
