MAJOR BOAT ENGINE REPAIR (part 1)

[@gbab53]

I had the same boat and motor,with the same problems you have. I did pretty much the same clean up as you guys. Put it all back together,it ran great for a short time. Started to see water in the oil. Found a crack in the block. New engine fixed it. Make sure the guys really clean that block really well, get a magnifying glass and look it over good. I wish you guys well. I enjoy this channel a lot thanks.

[@805ROADKING]

Gene Babine Thanks alot Gene!! If there's anything else wrong with it we'll have to sink it!!☺

[@59chevt]

you guys are unbelievably talented, and always a pleasure to watch.

[@805ROADKING]

59chevt Thanks Chev!! Thanks for watching!!☺

[@aaronbrown284]

it's nice to have a good crew of friends to help out. I'm the same way I am blessed to have a good tight knit group of friends around to work on restoration projects.

[@805ROADKING]

aaron brown Yeah Buddy!! nothing would get done without them Guys!!☺

[@chefdan87]

Ahh the good ole 4.3 GM Mercruiser engine. I always preferred the 3.0 inline four in my boats. Keep up the videos, you always seem to have interesting projects.

[@johnstrange6799]

What a team! As a subscriber this is what I love seeing from you guys, just attacking the tear down to save an engine's life so to speak. When it fires up, that is the sound of victory fellas.

[@805ROADKING]

John Strange Thanks alot John!! We appreciate you watching!!☺

[@thedunebuggyboi]

you guys are lucky! we had a 185 bayliner with the same exact engine that burst into flames as soon as we tried to crank it to go out on the water. be carefull when changing the gas filter because it caused the float to stick and fill the engine with fuel. nobody was hurt but caused around $9000 in damage but insurance is a godsend lol. good vid man hope all goes well!

[@805ROADKING]

***** Thanks Bud!! That's sucks, glad everyone was alright!!☺

[@thedunebuggyboi]

no prob man i love all ur videos!!!

[@WhyDidYouTurn]

Wow this is amazing, i got that same motor in my s10 blazer 4wd, 262 cu in 4.3L, These motors suffer from head gasket failure often, usually have to replace them one time with some high quality gasket and you'll likely never have the problem again for the life of the engine!

[@805ROADKING]

WhyDidYouTurn Yeah we replaced them with $80 marine gaskets!!☺

[@Darstar34]

Thank you so much for this video 💙💙saved my grandfathers boat👌🏾👌🏾🤙🏾!

[@scotty2307]

Roadking, that really looks like a mess. I really wasn't expecting to see the head gasket so thoroughly gone, as the exhaust manifolds are usually to blame for water in a marine engine. I have replaced a few head gaskets in 4.3 engines though. You should definitely have the heads surfaced. There will be staining or etching under the bad gasket areas if the leak has been present for very long. It is also possible that the gasket failure was caused by hydrolocking rather than being the initial water entry point. So check the manifolds. Freeze damage can also cause a crack in the bottom of the intake manifold. Those one piece exhaust manifolds are no longer available from Mercruiser. None of the aftermarket companies make a direct replacement either, as far as I know. The two piece manifold and elbow can be retrofitted. You asked whether that was called a manifold, or a riser? The answer is that the one piece is called a manifold. The top part of a two part exhaust system is called an elbow, or a riser, depending on whether it is a Mercruiser system, or a Volvo Penta system. Same thing, different nomenclature. After you get the engine back together, I would run it up to temperature, on the trailer, with water muffs over the water intakes, and then change the oil and filter again. Then if there is no new water in the engine, take the boat out and give it a good two hour run, and re check the oil. The heat will evaporate any remaining trace water. If you get new water in the engine, the exhaust manifolds are most likely to blame. I spent 12.5 years as a marine mechanic, and/or service manager at boat dealerships in Sacramento, and Redding, California. I presently sell marine parts and accessories at Harbor Marine Maintenance and Supply in Everett, Washington. Good luck with the project. If you need any help or advice, let me know.

[@805ROADKING]

Scott M Thanks alot for all the great information!! I appreciate you taking the time to type it up for me!! Hopefully the bottom end hasn't been wiped out!! We won't know till we get it back together and running!! I'll definitely contact you with any questions!!☺

[@ziggassedup]

It looks like an old Buick V6 engine...They had an oil pump in the timing case here and EFI with electronic ignition (No Dizzy)...The screen on the oil pick up was tiny and the balance shaft bearing was always noisy and the cam bearings(only 3) would peal the center one out of the block and then the cam would snap in half.!...The heads used to crack quite a bit and the valve seats would hammer up in the head on the ones we had here in OZ.I've got the next carnation of that engine at work at the moment with bigger problems than a blown head gasket...lol

[@duanepierson4375]

Jersey Guys! You guys are the best! From a former JG.

[@retrorestore]

Wow, that's one big messy job but you guys are doing a great job and getting it done.

[@805ROADKING]

retrorestore Thanks Mate!! You're doing a fine job on that Ol' Triumph!!☺

[@GrandsonofKong]

I use to have a 1963 Owens 30' Cabin Cruiser with twin Chevy 327's. Those Water Jacketed Exhaust Manifold/Risers are awful if the rust up though.. but new boats have sealed cooling systems with a heat exchanger...so nice anti-freeze based cooling for the engine and the sea water get injected in the exhaust to help keep things cool. On my old Owens seawater was just sucked up and pumped through the engine and out the exhaust...UGH had to constantly drain the block and flush it with fresh water after taking it out....nothing worse than hot saltwater for cast iron......use to use a lot of anti-seize on that thing!.

[@805ROADKING]

GrandsonofKong I was surprised we didn't have trouble getting any of the bolts out!!☺

[@coolrides]

You weren't kidding when you said "major repair'! Very interesting! Never really saw sludge like that before. :) Jack

[@805ROADKING]

Jack R Yeah that was crazy!! I never seen it that bad before either!!☺

[@harperjmichael]

It's definitely been run for a long time with water in the oil. I'd be putting new bearings in the bottom end too. I just had to put headgaskets in my 89 Chevy and I used diesel to clean everything good too. Those 4.3's are the same as a 350 just minus 2 cylinders except that's one of the newer ones with the balance shaft above the cam. They tend to crack heads pretty bad.

[@starpuss]

That looks like a fun repair! I think after that I would just pull the complete engine and check it over.

[@minibike3226]

wow subed to both of you

[@805ROADKING]

***** They all look like fun when you start, not so much after 8 hrs in 95 degree weather eh!!☺

[@rich2034]

I've said it before....you have some great friends!! That's a lot of work, sheesh!

[@805ROADKING]

Yeah they're a great bunch for sure and not afraid of real work!!☺

[@88fiveoh1]

As a fellow mechanic its always fun to see destruction. I see in the background the alamo is back together. When are we gonna see the next video of that.

[@805ROADKING]

88fiveoh1 Good eyes Bud!! This Friday!!☺

[@john.johnb_online1438]

Wow Awesome ! Surprisingly the motor didn’t seize up

[@locouk]

All that oil water mix, I'm sure Mac Donald's could use it for their fries. I used to see a lot of the oil emulsification on the smaller engine Rovers and Jags back in the day, the aluminium cylinder heads would warp and crack.

[@805ROADKING]

Green Silver I've never seen that much water and sludge in one engine in my entire life!!☺

[@shabear1000]

great coverage of the disassembly Roadking. with that much water/sludge in that engine it couldnt have had very good oil pressure, im wondering if the main and rod bearings are ok. sometimes that water/sludge with low oil pressure will compromise the bottom end. as far down as you have this, it may be worth pulling it out and checking the clearance of the bearings. anyway, great video my friend.

[@themotorfreak1]

Looks like a Chevy 350ci. I've seen about 20 of these in the past month go through a buddy of mine's shop. If you come down to lloydminster AB they sell for cheap. As soon as I seen water I was like ' oh f+-k. Water in the cylinders means time for a new block.

[@herbienbrian2]

Woof, its a miracle that thing didn't eat itself up.

[@krazy45cat]

Major job is right .My buddy Bill does this kind of work all the time .Ya might want to get those manafolds checked out as well . Make sure all the water jackets are still ok . Gerry

[@BoY860]

looking for some advice. I know nothing about boats, a little experience with motors. Im looking to trade a rifle for a jon boat 16 footer with 70hp evinrude (with console and all that jazz). Older engine says it needs a tune up and what not, Whats the most it would cost to get an older outboard rebuilt and running good. what should i look for when i go to look at the boat? any help is appreciated thanks.

[@albertini83]

Is the piston on a marine engine different from the piston in a car engine ??

[@ernestoandre82]

I'm actually doing the same thing to the bigger brother 350.. I just find it funny how they cut the 350 2 rear cylinder.. make sure the exhaust manifolds are not rusted to the point of water intrusion

[@805ROADKING]

Ernesto Andre they looked OK!!☺

[@buddylight2191]

It shouldn't have leaked water between the cylinders where the head gasket was blown. Is there another blown area on the gasket?

[@805ROADKING]

BUDDY LIGHT Nah the whole gasket was separated blown away!!☺

[@buddylight2191]

I recommend soaking the entire engine when put back together with CRC Corrosion inhibitor.

[@kevinfitz89]

Is the exhaust aluminum? Haha haha just look at the rust and big weld vain running up the middle

Excuse my ignorance. Are the gaskets the same as an s10 gm motor?

[@805ROADKING]

No they are a little different!!

[@andymandyandsheba4571]

hi EK was it just a head gasket or the inlet manifold gasket it looks an interesting job i used to take on stuff like this in my younger days as long as there is no cracks in the heads things should be ok i would get the heads crack tested and skimmed then you know there not warped great video cant wait for part two

[@805ROADKING]

Andy Coakes Everything looked OK!! Too expensive to get crazy with it!!☺

[@andymandyandsheba4571]

good thing ya found it before the engine hydro locked !! That bends rods and all kinds of bad things happen with that ..

70hp is a big outboard but still a small engine, im guessing if i can work on motorcycles a some car stuff i can handle a boat motor, i just want to make sure i dont get stranded.

[@MrComaToes]

I always get a kick out of seeing MERCUISER on a GM engine! I mean I know it's not the same Mercury as the rebadged Fords are, but still. Then there is the fun factor of buying ACTUAL mercuiser parts for that engine! If it's marine quality parts well, it GOT to be heavy duty and cost a LOT more. Hahaha Nice boat though.

[@AeroSport103]

Its time for a rebuild. No problem getting parts for 4.3s...

[@805ROADKING]

***** Nah!! that boat ain't worth the expense!!☺

[@wildcoyote34]

805ROADKING make a trip to the junkyard and get a used engine ,, you should be able to find a 4.3 pretty easy and if you were adventurous you could put a 350 in it's place ,, just gotta get manifolds ,, all the other parts are the same including the waterpump

[@NorthernPerformanceGroup]

I would proble say that that motor has bent rods it proble the cylinders and bent the valves rods the motor will proble knock un less you rebuild it

[@barfass]

Wow, looks like heat caused that head gasket failure but maybe that was a common issue. So many things can go wrong with those to cause it. You guys have your work cut out for ya!

[@805ROADKING]

barfass Yeah it was probably a combination of things that caused it to fail!!☺

[@MrOramato]

You sound like Cliff from Cheers.

[@DaddytechEnt]

Wuter? :o) That looks a lot like the 4.3 litre i rebuilt in my daughter's 97 S-10 Blazer. yeah i thought so, hasn't been that long since i was rebuilding hers from the block up too. Even if that timing chain wasn't loose i'd change that and the gears out both. yeah that gasket is GONE for it to be throwing that much water out and turned the oil like that , someone really gave that thing hell since the initial damage was done too. They aren't that much. i bought a double roller gear set and chain with the new timing chain cover i think it was like $80.00 for all of it. Yeah as thick as that sludge is all through the motor someone ran it like that for a while. The sludge is brown because some of the brown from the rust mixed in the oil and water. other wise it would just be gray or gray and white. i know a guy that goes around to local shops when they pump gas out of a diesel tank when someone makes that mistake and gets what they pull out to clean his parts and things with. they usually give it to him happily because other wise they have to pay to dump it somewhere and it's kinda expensive from what he tells me.

[@outdoorsman310]

make sure the water pump works too

[@simoncrabb]

That sludge put me off ma lunch!

[@805ROADKING]

Simon Crabb I wanted a chocolate ice cream cone after seeing it!!☺

[@lerch122]

I would have taken the motor out.had a motor with the water pump on the end of the cam shaft so when the seal leaked water ran into the engine.A bad idea but also caused by me running the engine with out water going through it.We learn

[@chevydiesel350015]

LOL They would of been better off using the engine as a water pump to spray themselves then going boating haha. Can't believe they kept running it like that.

[@MalcOfLincoln]

Few years ago a friend had a Sealine with a 350 small block Mercruiser. It dropped a valve seat insert. We think? it might have been converted to run unleaded, hence inserts. Quite by chance I met him on the first trip after the repair, done by another friend so not that expensive. Got a brilliant pic of me coming through the Glory Hole (High Bridge) in Lincoln......driving a £30grand boat and drinking REAL Champagne and I was wearing my very expensive Ferrari T shirt given to me by another good friend.
