I have an Atomic 4 in a 27" sailboat. The engine ran great last season and I winterized it after the boat was hauled. We launched this season 4/22. The motor runs great when in neutral; responds well to the throttle, etc. However, when I put the motor in gear and increase the throttle, the engine seems to bog down. It's as if the throttle has little affect; there seems to be no difference between a quarter-throttle and full.
Today I took the carburator apart and cleaned all of the jets, etc. It looked to be in good shape. I also cleaned the plugs, each of which was pretty black. I put the carb. back on and although there seem to be some improvement, it was short-lived.
The only change I made to the fuel system since last season was to install a water/fuel separator (the one recommended for the A4).
I took the boat out the day after we launched it. It seemed as if the "bogging down" grew worse with time. Once back in the slip, with the motor out of gear, it revved like nothing was wrong.
Any suggestions as to how to fix this problem will be greatly appreciated. Could it be that my prop shaft and motor need realigning? Please help...
