    Check your Carbon seal for the drive shaft.It is right behind the motor were the drive shaft goes through the hull.If the retainer clip gets worn it will let the metal part of the seal woble and it will leak.

    Check the nose cone on the impeller it has not come off the impeller and moved forward up against the carbon seal. And one other thing check your shark teeth in the pump make sure they are not broke.

    it also only had 60 hours on it, so carbon ring?

    any good advise!

    I've seen the carbon seal go out at 25hrs(mainly 3 blade props).Also check the bumper on the end of the drive shaft(motor end) I'm fixing one of those right now.If the bumper is bad it let the pressure off the carbon ring.

    No the rubber bumper is on the end of the drive shaft in the back of the motor.
