Help! Winterization gone bad! Have a cracked Lt 1 and am wondering if anyone has any ideas on what to do that wont cost $7000! Hoping to be able to fix the problem under $4000. Have a '96 Prostar 190. Trying to find an engine online, but not having any luck. Can I buy a car engine or does it have to be Marine grade? Any info and insight would be greatly appreciated! Want the boat this summer, but have limited funds. Thanks!

I may have a source for a rebuilt core for an LT1, but it is in Alabama. I'm not sure if he will ship or not. I think he was asking less than 2k for it. Let me know if you are interested and I will call.

Do you know where the crack is? I got lucky once with a cracked block in a chrysler marine eng. drilled the ends of the crack, JB WELDED it and got the season out of it....

I have a 93 prostar 205 with the LT-1 that I just put in a new long block and am having ignition problems. If you are changing to a different engine i am interested in your cracked block engine for parts like the Mefi 1 computer/reluctor wheel, etc... please call

Buy an automotive short block and have a machine shop check your heads for cracks, and freshen up the seats and guides.

Just get an automotive block. There is no difference. The oil pump drive broke on mine, it didn't ruin the block but I did have to take it apart. The cam was toast. The cam was a standard Chevy part that was discontinued. I bought a comp cams replacement and haven't looked back. The difference is the ignition system is a little different. That is all. Use the ignition system off of your motor.

If you don't mind me asking what went bad or wrong with the winterization?

With out grinding salt in the wound, I too would like to know what went wrong.

Seems like you may have a lead, but the short answer to your question is that you can get an automotive LT-1 engine and switch out the marine specific parts. Just be sure to double check and ensure all electrical parts are marine. You don't want the entire boat to go boom.
