I have s 2004 mercury 90 hp two stroke on a 22 ft pontoon boat. I just purchased the boat three days ago. The engine starts and idles perfect. It seems sluggish on take off and will not get past 3800 rpm and 14 mph by GPS. I have checked the throttle/carburetor linkage and it appears to be opening fully at full throttle. The oil injection appears to be working as is the oil injection alarm. Compression test by the dealer was 110, 110 and 100. This was a cold test. I found the two yellow wires coming out of the stator to have melted together. I separated the wires and redid the connections. Up until this point the tach didn't work. It now works fine. According to the dealer the voltage regulator is new. It has a 13.5x15 prop on it. The prop has flight damage, but in my uneducated opinion, nothing that would cause such poor performance. I haven't checked the spark to each cylinder. I will be doing that today. According to the onboard voltmeter the charging system appears to be working. Could the stator be bad? I have a lot of automotive experience, but very little outboard. Any help would be appreciated. Additional info, the motor runs smooth all the time. Starts easily and there is no noticeable miss. Just a lack of power. Thanks again.
