    ? after new motor

    well got everything all back installed after having to purchase a whole nother 787 motor.


    took about 10 secs of turning over to fire up for its 1st time.

    Runs and sounds smooth, but after about 4-6 secs of running(water hooked up) the skis revs start to rise slowly. The RPMs were still rising at what sounded like 3k, so i shut it down.

    Ski has oil pump still hooked up and working. I premixed 1st tank as well. I just installed all new fuel lines, fuel filter, cleaned carbs twice, etc.....

    i was thinking maybe an intake/exhaust leak? sound right??

    Does it keep going up in RPM's? Check you adj screws on the carb. Mine did that and found out that my front adj screw was slowly backing out. I know i had it 1 1/4 turns but when I would have it running notice once I came down from RPM the idile was higher. recheck and my screw was around 1 1/2 to 3/4. repleaced the spring on the screw been fine since.
