Hi, i just built a 90 force sport jet and it's getting hot.its has plenty of water coming out of the 90 degree fitting that goes to the exhaust plate.the motor was built not long ago buy someone else.when i took it down you could tell that the motor had run hot before.wires were melted and all three pistons were scuffed and out of round.from looking at the exploded diagram i don't think this engine has an exhaust stuffer.no water comes out of the thermostat cover when it's running at the launch.is the stuffer my prob?should water come out the thermo cover ?
