Help - Was getting ready to trailer my boat about 2 months ago, pulling up to the dock and all of a sudden, like you tripped a switch, the motor would not go above a fast idle and would not even get on a plane with just me in the boat. Had been running fine prior. I have since cleaned the carbs, changed the fuel line and bulb, bought a SECO service manual and changed the lines between the carbs. Still no success. When running WOT the engine will surge somewhat but still not get on plane. I bought a compression tester and checked comp, it is somewhat low 119/112/102 but dont know if that is the prob. Changed plugs, they were black like they should be and took it back to the lake, still no luck. Pulled the plugs, they were somewhat clean but wet with fuel, not steam cleaned like there was a leak. Cant figure out if my problem is fuel or spark or both. Any ideas will be appreciated.
