    The most important thing about pisser location is making sure that you aren't gonna dump hot water into the footwells. On my first GPR we had put a pisser under the grab bar at the rear of the seat; unfortunately, at idle the water didn't have enough force to make it to the back deck, and I would end up with hot water all round my right foot. Didn't burn me, but it was annoying.

    I hear ya on not wanting to drill a hole in a new ski. I have an 08 also and when I did the jetworks mod I bought a stealth "Y" fitting from carl and used that to exit water from the exhaust mod...

    maybe you could route the water exit that way as well...

    also a friend had the pisses below the grab handle out back and when traveling the wind would redirect the water all over his arse...LOL...
