One last one. I know it's expensive but if you sell your heads and some other engine parts you might come to your budget.it's brand new.

Some day I'm going to ask bigblock to find me the 300hp ecu for my v8-225, with a budget of $200, and see how long it takes him.

Thanks for all the research BB! That's pretty much what I found, but I'm hoping my plan of rebuilding a new engine in a new block casting with all of my components is going to the best route.

I've been the the wholesale auto auction business for over 20 years, and as a result have developed a pretty good network of engine builders, mechanics and parts.

I talked to the prior owner last night and found out that this current engine has about 80 hours on it. I also asked how he determined if the block was cracked, and he said when he flushed it water came out down low on one side? Who knows, they may get the engine out and find that a freeze plug has pushed out! If that's the case, I'll still have them tear it down and freshen it up, but it'll eliminate the need for another block. (fingers crossed)

It's definitely promising that you haven't actually seen a crack. Sounds like you have the resources to do it right whatever you do find, though, which could mean an absolute steal of a boat.

Check the oil. When my father cracked his block there was water in the oil.

He just ended up giving the go ahead on the rebuild. He has a 7.4 in his 226. He's getting a new block and rebuilding with the remainder of what he had. Out the door he's looking about 3500 with install but he did a lot of the work on his own. He just retired so he has the time.

I've been pretty busy lately and haven't had the chance to post in awhile. When I was down in the hull unbolting the seat cushions I saw the crack in the port side of the block. I was kinda hoping there might be an off chance that a freeze plug had pushed out, but that's not going to be the case for sure. We're going to try to pull the motor next week and start the process of stripping it.

All the seat cushions that need love have been pulled out and ready to be recovered.

This is going to be a fun project!

Today my motor was pulled and stripped down to a longblock. When I took this picture I was having a very weird feeling. I'm happy that progress has begun, but at the same time a little creeped out because my boat looks like a salvage wreck. I guess in a way it kinda is... The motor was setting on the ground and the entire interior was loaded into the back of my truck.
