    Cooling issue

    So we went out this weekend and had great conditions, 65* and 51* water.

    I redid my cooling lines so that they come out just in front of the right footwell.

    Last fall the Mag Cylinder stream was really strong (6' Arc)and the center was ok, (2 ft Arc) PTO was just dribbling out and overheating.

    I added 2 valves to restrict flow on the Mag and CTR. and now have it fairly balanced. But man the water coming out is really hot. 50* in and to hot to touch coming out. After 10 min of riding, all cylinders are too hot to touch without burning my fingers. even in 50* water (no thermostat)


    What did I do wrong?

    Are you sure that all the gasket passages are free and clear and the head gaskets are installed correctly? Water pick-up strainer clear?

    Water pick up strainer???

    Where might that little wonder be?

    head gaskets are correct
    paper gaskets for the new outlets are fiber with grease no putty or caulk

    just went and looked. the filter is not clogged, because it is not there. maybe I got something up inside. but I still have flow

    I will pull the pump tomorrow

    funny, that pick up is way outside the high pressure area of the pump. figured it would be closer to the stator

    also notice two chunks out of the stator.

    will take pics tomorrow

    The holes in that mesh plastic intake screen inside the nozzle are angled towards the front of the pump.

    That is a high pressure zone inside the pump, as the jet pump water flow is constricted by the main exit nozzle.

    It's close to the trailing edge of the stator at the reduction nozzle. As the outlet is reduced, the pressure is greater. Its a good location for it.



    edit: I shouldn't have slowed down my internet to save $.
