Lost power while on the lake, but putted back to launch on one cylinder. Got it home checked plugs and found water on lower cylinder. Checked compression and 0 on same cylinder. Other than head gasket are there other possible entries? Is it possible to buy just the head gasket or will I have to buy whole gasket set?<br />Also after removing head, I can see some minor scoring on this cylinder, any thought here (time for rebuild)?<br />Thanks,<br />P.S. Great board tnx iboats
