Recently purchased a boat like 90% of those seeking help and unfortunately got hosed by the prior owner. He cracked the block JB welded it and painted over it. Good enough for 30 minute test run and the dip stick placement hides the "milk oil" Marina said the heads were in apparent okay condition but do not know until I pull them off. Now I know the proper way to do it is shell out 3,000$ and buy a reman OMC shortblock/longblock. But, that is not happening as I will never get near my money back out of it. If I can't do this I'll cut my losses and let it go.
I want to take off the "water accessories" and swap it over to a cheap 350 long or short block out of a truck. What blocks can I use, I now know its 1 piece rear main seal. I know I need to swap out the plugs for brass and use "marine grade gaskets" whatever the difference between automotive gaskets is besides the price. I do know that I will lose some power and long term reliability by doing this.
