The engine seem to intermittent misfire on one or 2 cylinders. In neutral and idle all cylinders fire, no problem getting 5500rpm. In forward on water 3000-3400 is max. If backing off the throttle i notice that at least one cylinder tries to fire, but only intermittently.<br />It is not a gas related problem, and the powerpack is brand new, charging system ok. I have started to suspect the coils?
