Re: cracked block
if you use the boat infrequently, and other freinds are there to pick u up and tow you back, then put JB weld in the crack and hope for the best. Otherwise, to do a quality repair, buy a new engine. small block chevys are the least expensive on the market and you'll have piece of mind knowing after going out on the lake or ocean, you have good equipment that will get you back home when your done. - think about what you already spent, throwing good money after bad. Remember, you can't polish a turd!
