1989 Evinrude 110 Hp Cracked Block, Is This Salvageable?

[Shakedownscott]

I have been struggling to get this motor apart. There is a lot of corrosion due to saltwater use. She needs new pistons and possibly bored out too.

After removing the rectifier I came across this crack in the block.



The crack does not seem very deep and does not run into the water jacket. One question is, how did this happen and is it common. Also does mean the block is not fixable. I was thinking that maybe it could be welded.

Thanks for any advice.

Sorry to say......that might be history. Something had to slap that from the inside for that crack. True it is "behind" the water jacket and the tolerances inside there are tight. At this point if you weigh out the rebuild parts list versus another (hopefully freshwater run) motor..... I think you will come out ahead buying used.

Keep your eyes on craigslist there was recently an older used 115 (that needed work but nothing of your magnitude) or possibly people are starting to get rid of boats with good motors but the boats has issues. I purchased a V-4 that way and now I am restoring the boat just to play with it. A rebuild (pistons, gaskets and not counting machine work in parts alone can be over $700) of the motor might be a fight because of the salt water too ;(

Well in answer to the repair bit, yes it could be welded, thats pretty easy to do and nothing special at all.

But like said above, something has given that a good hard smack to crack it.
now being as its pretty corroded you will probably spend more money on nuts and bolts than the engine would ever be worth.

best to source another engine and maybe break that one down and sell all usable parts to get a few pennies back.
it will also give you some knowledge in the workings of an outboard and exactly how they are built.

you will be far better off getting a later engine for less money than that will cost to fix.
and you dont even know yet if the crank and rods are any good ?
just a new crankshaft and rods alone is more than a decent running motor would cost you !!!!!!!!!!

just put this one down to experience and enjoy stripping it down.


good luck in your quest

Thanks for all the advise.

When I picked up this boat and motor I didn't pay much for it and was planning on putting the "saved" money into rebuilding the motor. I figured this way I would have gone through the entire motor and made sure everything is in good shape. Looking like this is motor may be too far gone. Is there any way to use this block?

I have been checking out Craigslist and do see some other possible outboards and most around here are freshwater only. Too bad they are all in Burlington I tried to bring home a boat motor trailer a few weeks ago just for the motor. My wife said no way, not until I get rid of some other projects.

Would this happen from the piston slapping from a worn piston? Or would it be something worse like a bend rod??

I am sure you guys are right about this being a losing proposition, at least financially.

Re: 1989 Evinrude 110 Hp Cracked Block, Is This Salvageable?

No thats not piston slap.
much more serious i would think.

if you do want to go all the way then the block may be salvagable.
take it apart and see whats realy going on in there, check the crank for trueness and no pitting etc.
check the rods and the pistons.

maybe this was done a long time ago by previous owner and he just stuck a new rod in and didnt know the block is cracked ?

wont hurt to strip it down and then re-asses the damage.
the welding of the block should be ok unless its a lot worse on the inside !!!!!!!

that could even have been a bad casting that has lifted. might be cosmetic. Break the flake off and see what lies beneath. That will tell the tale...

Patience The deals will start coming in following labor day....... people will be looking to unload and not pay storage fees. Burlington to Chester is not bad at all....... I am in West Rutland/Castleton.

That is a beautiful part of the state, do you get out on Bomoseen and Lake St. Catherine much? I keep saying I am going to get over there to do some fishing but always seem to end up on the Connecticut river.

I think the best thing I can do now is get rid of my old truck and a junk car or two, so I have room to drag home another boat project.

It seems like it could be a casting defect or something like that, it is really thin piece. Also there is something similar on the other side just a lot smaller.

peel them off and see if exposes anything of concern

That defect is in the cooling galley between the heads. Possible the engine has been running for some time with that defect and has produced no serious consequences. Certainly no critical tolerances there. Agree, peel that sliver of aluminum back. Likely any good aluminum welder can restore that part of the block. Could be an inexpensive repair.

Agree + 1 with the above two posts...........

Re: 1989 Evinrude 110 Hp Cracked Block, Is This Salvageable?

I peeled off the piece of aluminum. It is very thin and just flaked off. Looks more like corrosion than anything else. What do you think?

Re: 1989 Evinrude 110 Hp Cracked Block, Is This Salvageable?

If it where me seeing that it flaked off like a couple have said it may just be casting flash that fuinally peeled off. I would clean it up and go to a welding store to get setup of what us welders call crack check or dye check. It comes in areosol cans and is realatively inexpensive. We get the setup for I think its $35. It has a cleaner, the dye and then the developer. It will show if the crack does in fact penatrate the chest.

Toss the whole block into the recycle pile as you will never get all the corrosion out and will have cooling problems as there are to many freshwater blocks out there that can begotten cheap....JMO

Yes there is some corrosion in the water jacket, but I can't see where it would block the flow. Is there somewhere that I should check for blockages?
