    Ball Valve Install for Yamaha Visibility spout

    Finally got around to installing my spray valve, posting since the valve supposedly handles 300 PSI, a little less than my pump and took me awhile to find this silly part which I would like.

    Viton 1/2 Valve and Oetiker 18.5 clamps fits OEM hose.

    Micro Ball Valve, Polypropylene, 1/2" Hose Barb (LVHB050V)

    Can you post a pic of the valve installed on your ski? Would like to see how & where you spliced it in.

    Thanks badjoka. This is exactly what I have been wanting to do. My wife likes the "visibility flag" (she is safety conscious) but the spray can be a nuisance when towing someone or riding in a group. I want to be able to turn it off or on depending on the scenario.

    Welcome, Will make a world of difference for people riding near you. Valve is high quality and very light. I removed about 3 inches of hose to accommodate the valve length, otherwise hose gets kinked.

    I valve'd mine a few seasons back - one of the top-ten mods, as I often rig fishing cooler/gear on the back, so shutting off the flag is paramount.
    Another benefit not often mentioned is being able to run the valve partially-open, so that the spout is still there yet tamed-down quite a bit - which is useful if you still want a little-something to visually monitor nozzle pressure/thrust-loss conditions.

    Just curious, is there anything that has to be taken apart pump wise or reverse gate to install this.

    that was my next question. So you went with a polypropylene valve instead of brass. Any particular reason for the poly valve instead of brass?

    I would suggest that a metal valve is going to be too heavy. The valve is only supported by the hose stiffness.

    When riding in rough waters the hull slams around over the waves and a heavy metal valve is liable to yank on the hoses and possibly dislodge them, or perhaps get in the way of the reverse bucket.

    Note: The water pressure for the visibility spout is modest. The plastic ball valve is not going to experience severe water pressure.

    Exactly, brass ones at HD were at least a lb.
