    Most everything has been rebuilt or replaced on the motor minus the stator. I am wondering what the motor acts like if the stator starts to go bad?

    Dropping cylinders sounds like what it is doing! But why? And what is the fix?

    It's not blowout from the prop being out the water.... the motor has been dropped to the lowest setting and moved up until i got blowout at highest trim. Then dropped back down

    RPM's drop quickly and speed starts to drop obviously. But the RPM drop is quick/drastic!

    Motor trim, yes. Right around 5500-5700 rpms, the motor just loses power.... get off the gas and it goes just fine.... runs good @5200 all day long, but that is 40-42 mph.

    With this 26 pitch prop, i gained about 4-5 mph. New prop, 5300-5500 rpm, 45-47 mph If i go much higher in rpms, i am assuming i hit the rev limiter
