Mercury engine runs fine at idle, but as soon as you accelerate the engine starts running rough. Once you reach 30mph it seems to be fine. If you hit a big wave, the engine will misfire and run rough for several seconds and then go normal. Last year a dealer changed the stator, trigger coil and the coils. The top RPM is 4800. I have lost about 7mph top end speed. Any suggestions.
