Help**The Head Bolt Heads are rusted OFF
The exhaust and head bolt heads are gone
This is a 1997 28 ft Scarab with about 500 hrs fresh water .From all the rust it looks like it sank with the Titanic. I am rebuilding this motor for my friend and I know the exhaust is garbage . Allready talked him into some aftermarket performance exhaust.
I have never seen one this BADD on the out side .
My Question is how do you recommend to get the bolts out so I can take the motor apart?On the exhaust I know I can use a cutting torch because were not reusing the manifolds. But the head bolts some of the heads are gone.With the out side being this bad I wonder if the block and heads are rusted out.He is a good friend so its going to be a freebie.But if the block and heads are too rusted in the water passages he might as well buy a create motor.

That is ugly Strip Poker. I would torch them all off, just be careful of the fuel. Also you could weld nuts to the head bolt as another option. What engine is this? It is amazing this is rusted that bad when used in fresh water, whats up with that?

I've never saw a fresh water boat with that kind of corrosion...NEVER.
If you can just grind off the tops of the bolt heads and try to break the heads loose.
As others said it may not be worth your time.

Must never have winterized it and WD40'd it properly
That's worse than most 10 year old salt water boats I've seen.
I'd keep a crate motor option open if I were you

He bought the boat new in 1997. its a 415 hp MPI.Its only been to the coast (Salt Water) maybe 5 times just for vacations.and I carried my Scarab also when we went . I guess he never washed it or flushed it after those trips to the salt. He told me he did??He did winterize every winter because I made him do it ,He just drained the water. I know he never put wd40 on it.He does not believe in preventive maintenance .
I don't think I can weld any think to some of the bolts. There is a few that the head is totally gone . i haven't even scraped any rust off and its that bad .the motor mounts are even in bad shape. One freeze plug looks like its made of metal its so bad.Its looks like the risers have been leaking and running down the manifold rusting and between the head and manifold leaking there also.
I think we might be able to torch off the bolts on the manifolds because it doesn't matter if we hurt them. But the head are going to be tough. if I could burn off whats left of the head of the bolt . if i hurt the head i guess i could spot face them Like when you angle mill the heads for compression??
