3rd owner of a 1990 Bayliner capri bowrider. Had a few long periods without use. Got it from my brother recently and got it up and running and did some other work as well. Have had it out on the lake a few times recently, and the boat seems to be down on power. Has trouble getting on a plane with any more than myself in the boat. Once its up on plane it seems to run well, about 30 mph at WOT at 5300 rpms. Ive went thru the link and sync a hundred times, carb adjustments, and just couldnt figure out why i couldnt get up on plane, put a brand new 13.75x 15p prop on it. Still, planing issues, so today i decided to grab a compression tester, grounded out the plug wires, removed all plugs, tried with no throttle and WOT and I got 110lbs in cylinder #1, 105lbs in cylinder 2, then i was actually surprised when i got ZERO on cylinder 3!! Aside from being down a little on power on acceleration, all else seemed fine. Im thinking i have stuck rings on that cylinder from the periods of sitting without use.The plug does have some carbon but not as much as the others (brand new plugs) ANY thoughts or recommendations on what to do next? How to unstick the rings?
