Took the boat out last night, tried to use gas from last year the boat started running really bad change the tank right away made it about a quarter-mile still running crappy, change the plugs ran a little better but not 100%. Finish the night out got up this morning pulled the plugs bottom plug/cylinder was full of water, top cylinder/plug was clean and dry. Did a compression check 139/141. Pull the head off and everything looks good inside no pitting on the piston and cylinder no problems at all. Question is if it was an exhaust gasket would there be water in both cylinders or is this just a head gasket
