    How to Make Jetworks Gasket

    Between all my monkeying around today with the pipe taken apart I messed up the jetworks gasket that came in my kit. It is just rubber. Can I make one? Don't want to order another. I am looking forward to hitting the lake this weekend since I havent been on vacation.

    yep, you can make one out of thick MIL rubber. I have done that on all the Jetworks mods I have done. I don't trust the thinner rubber gasket they come with [as you can see they tear easy] & they can possibly ballon out over time I beleive.
    Mine has been on my ski for 5 years and still perfect. Just remember to put the OEM metal gasket against the stinger first.

    I have seen the rubber gasket that I recommended failed on several skis, make a couple of gaskets with thinner rubber material, go to Home Depot roofing/gutter section and look for aluminum material that is .015 thick, trace the round gasket minus the water passages and cut it with scissors and clean it up well. Use this in between the 2 this rubber pieces. Ill never fail. You can find aluminum sheels about .010 to .015 at any small hardware of hobby supply shops. also.

    The rubber gasket I am using Chris measures .122 thick on my digital caliper !

    I have enough material where I can make you one. It is industrial grade rubber. It has never failed on the skis I have installed this on or showed signs of failing.
    I removed this coupler last year on my stinger to check it and it is still in perfect shape. No distortion or swelling/stretching.

    Let me know and I can mail you one if you want one

    Yeah, and it will cost you rpms on top.

    At MBIII, I was setting my J/W on both boats on the Friday. The ported boat was leaking water outta the pipe when I disconnected the valve.

    I was wondering why my rpms kept dropping lower and lower over the last 6 weeks.

    I suspect the gasket is leaking water into the waterbox on top of what I am injecting.

    I havent had time to pull the pipe yet and confirm.

    I think mine was leaking because it has felt slower and slower out of the hole. But my top end hasn't been hurt. Then I noticed I had some tubes backwards!! I was trying to push out exhaust water through the bildge siphon exit! How I did that I do not know but now it is fixed. Maybe a little less water pressure now.... more rpms?
