Super Jet Pisser flow opposing throttle

[mike b]

Was water testing a completely stock 701 superjet and it had a good stream coming from the pisser from idle but when I gave the ski throttle rather than the stream coming out farther, the stream from the pisser was less than idle. The flow would return to idling amount. Any ideas? Cylinders were cool/light warm, Stock pipe was warm/hot, but not not sizzling any water

Does it seem to run good?

I blew a head o ring (ada head) once and aside from reduced performance I also noticed the pisser was acting as you described. I also blew one once and did not know it until i had the head off just for a monthly inspection. I really love an oring head, so easy to pull off real quick.

yeah this is just a stock head. Plugs don't look bad/wet tho. I ran in on the hose today and noticed if i played with the hose where the Tsection is to head/pipe/pisser that I would get flow. Maybe the Tsection is placed too low? I just put in hose line so maybe I did something incorrectly which I wouldn't think make the difference. Could water just be dumping in the pipe? and do I need to have the hose from the head go back into the pipe? could i just run this straight to a pisser instead?

I wouldn't alter the stock water routing. Im PMing you my number, call be around lunch tomorrow.

Did you come to a conclusion? Just curious..

Changed the Tsection and hoses up to longer off the head and I had good flow out the pisser, motor didn't burn up and I was running it pretty good. Was a risky and possibly expensive way to test it out to find an answer but all went well hah.

Awesome, you should be good because the head temp sensor will let you know if it gets too hot. Glad you figured it out.
