Either that, or http://usengine.us/mercruiser.html

Or, if your engine is otherwise "OK" find a local reputable machine shop and have them rebuild your current engine.

theres not much typical about boats...

a serial number to the motor and drive would help the "pros" here help ID the motor and drive for you.

I know you CANT use a automotive cam in a boat engine... not sure why, i think the lift and durations are different due to constant RPMs...

it has to do with cam even timing, you need the exhaust to close before the piston starts moving back down so the engine don't suck in water.
