Damage boat project

GT-40 heads are good, but GT-40P's are better. any automotive guys will try and talk you out of the p's because of the conflict between exhaust and plug in a car, but that is not an issue for our exhaust riser arrangement.   the P's are cheaper too if I remember correctly.    I think if you are going with a used truck motor, leave the cam for now and see how you like it.   No reason to swap it out unless you're looking for something more than the stock will give you.

Crazy how certain parts of the country, Pacific NW for sure, love to drill snaps all over the boats for covers, ughhh

manifolds are the first place I would start as well, both of mine were cracked from the freeze, and that could be the source of your water leak.    FWIW, I agree that you should change the oil and see if you can make it run. then compression test. The registration looks like its a Florida boat, and if I remember correctly, you said that it was a recent transplant to the PNW, so salt is definitely a possibility.    If you were wanting to make only one good boat, the engine from your 97 would be a direct swap, if you were inclined to go that route.

Mike, are you aware that the manifolds are essentially double wall?   The internal vessel is for the exhaust, and the jacket is for water.   if the water jacket is leaking that is likely what you're seeing on the left.   the internal jacket could still be bad, as could the left.    they need to be removed and pressure tested.   There is a thread on this that I did a while ago, you can find it in the FAQ thread.   there are several ways to perform the test, but I believe all of them involve removing the manifold.

Got the intake off, everything else seems to look ok. I though that hole in the e sidewall was a issue but after doing some google searches it looks to be normal. Found a intake manifold off Craig's for 80 I might pick up this weekend.

Pull the motor out of the boat and do it right!!!!
It's so much easier to work on it while on a stand.

You are this far, I agree.
Looks like another great deal for you! You may be able to quit your day job!?

That's going to be my bigger problem is just lifting it out of the boat. I have a cherry picker but it would reach over the sides. I ordered the exhaust manifold this morning.

I also noticed now that battery is charged the ignition light won't turn on.   Is there a weak link when it comes to corrosion?

Take the wheels off of the trailer

Working on getting the shine back. Started with wet sanding, just picked up some polish wax to hit next

You guys are talking to a post.
Unfortunately, this guy has a legacy of ignoring well-informed and good-intended advice.
Another half-assed Nautique.

Peter,
I don't think the "buff" job will take Mike long so he can get back to the important fix.. I think I see a container of Poly-glow he's using!

Peter,
I sure don't feel we enabled him simply because even though we told him the ripped out strut was fixable, I feel he would have gone ahead even if we told him it wasn't! My concern is for whoever purchases one of his "projects" because he didn't take any of the advice we tried to give him on the "repair".

Makes me happy, Mike. Seriously. Thanks for the update.

Good to see you finishing the boat. I don't care if you are a flipper, more power to you, just make sure you go a good job and ensure the boat is safe, would not want anyone hurt by a repair failing causing an injury or the boat to sink. It is always betting to put extra layer of glass and epoxy on the inside over the repaired areas for extra strength..
