    Or uncontrolled...AKA a pressure vessel...Search jet boat water pressure.

    FWIW, they can make enough pressure to blow the welsch/freeze plugs clean out of the block...In excess of 50#...

    I checked it on my 753 Hamilton Jet(3 stage). It has 2 water feeds to the engine. I used one to the engine with pressure relief valve and the other one I had a Psi gauge on.

    At WOT the gauge went of the scale at 200Psi
