Dont waste your time. Get a new or remanufactured engine.

Saw the pictures on your other thread. Unless you are a good shadetree mechanic, and can do a complete rebuild yourself, get a remanufactured marine motor. You'll also need new exhuast - plus some other small but expensive parts (hey - it's a boat). Rough guess - around $3K to get it back on the water. Welcome to the world of boating where having fun takes a free flowing wallet.

Good luck.
