    I think it's the check valve ? That is on the water line from the jet

    Some guys run a ball valve to limit the amount of water getting to the engine. To allow more or less engine temp.

    Some think the valve at the pump outlet will allow air pockets in the engine. Some put them after the engine but then the engine will see full pump pressure.

    The best setup is a relief valve instead of a valve in line.

    Perfect thanks. One more question. I put a T fitting in the line from the jet an plugged it. But when I go to hose run it is that where I would hook the hose too ? Or is there a different setup ?

    Assuming your refering to a "T" so that you can run the boat on a garden hose ? (assuming you elect to do this) the place to for the "T" could be eiher before the ball valve at the jet casting outlet

    Default Check Valve

    Ball valves restrict water flow and create air pockets in your engine. I would use a check valve set at 8 to 12 PSI with the excess water being dumped over board.

    Ummm - you meant to say relief valve, right?

    To the OP: IMHO, the ball valve is only there to allow you to shut the water off if you're on the lake/river and you blow a hose or a freeze plug.

    And to stir the pot on this (again), I'm going to say he should use a pressure regulator instead..... ;>)

    Ya can call it what ever you want but is does adjust the water pressure to the motor.
