Hello all.
I just bought the engine above. The PO lost oil pressure from a leaking oil line during an outing and then took the boat to the marina where they told them the engine was shot since it now had low compression.

I got it home and started it. Seems to start just fine, so I did a compression check. The numbers were low 60 -100 psi so I poped the heads off to take a look. To my surprise the cylinder walls look pretty good. Only light scuffing and no gouges. It looks like a hone and some new rings will freshen it right up.

OK here's my question: Can I just remove the Reed Block to get to the rod caps for removing the pistons, or does the power head have to come off and the block split?

Powerhead will have to come off. Mine is off right now. You will have to split the block. Might as well plan on a complete rebuild. But if your pistons, crank and block are ok shouldn't be to costly.
