Ball Valve Install for Yamaha Visibility spout

[badjoka]

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.

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

[badjoka]

Sure

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.

[badjoka]

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

Here is a pic of mine. Came in a two pack for the valve for like $8-9 at lowes. Works well and can easily reach over the back of the ski and switch on and off.

The water pressure is modest when the valve is open and the water is unrestricted, however when the valve is closed and there is no relief the pressure is very high. I have blown the hose apart before the spout when plugging at the spout outlet because the hose is not that high a pressure rating. That is why I always plug at the pump with JB weld, its permanent but trouble free.

I would be sure the valve is pressure rated high enough and use a higher pressure rated hose before the valve. The visibility spout hose is not rated for the pressure the pump develops at full throttle. Remember all the cooling lines and such have a constantly open outlet so the pressure doesn't build up as high.
