so how many turns out from closed should a flow valve be its a single cooling b piped superjet. i think its at around 4 or somthing

Just check the pressure with a pop-off gauge. Try different pressures until you get the best bottom. I think jetworks recommends using either 2.5 or 3.5 psi as a baseline. It should say in the instructions.

ok

but if i had a tester i wouldnt be asking this question. i guess it varies from boat to boat.

stan (five-o-addict) ran his he way it came and loved it. doesnt it say that in stock setting its ready for a mildly built motor?

im over it

to confusing i guess all i needed was for someone to go in the garage and spin the flow valve closed and open it back up kinda like the setting on carb like 4 full spins out something easy.

Best way is to run a hose overboard and see at what RPM the valve opens. Every ski will be a little different and your water pressure may not be the same as someone else's at 4 turns out.
I have mine set to open at about 3500 rpm and it works fine for my ski.

ya

i tried that and nothing came out i had it tied to my truck and go the ski to at least 3k and nothing came out of it tried it as a lil turn to a few and nothing came out untill it turned all the way out and came apart. could this be happening do to the water from the bottom of my b pipe it goin got stinger. and should be the top to pisser.

I just turned mine until it was tight. Didn't know there was any "tuning" involved in them.
