    8800 rpms are way too high! Sounds like cavitation (sucking air possibly thru the carbon seal) Which ECU do you have?

    The carbon seal is your driveshaft seal. Are u getting more water than normal from the drain plugs after a ride? You may need a much taller prop to keep from spinning it out of the hole. Pm jerry (green hulk) on what props are working with his EMS setup. Are you running the SS wear ring?
