    1-drill out the holes in the J pipe

    2-tap a waterline into the TOP of the box with a valve to adjust water flow

    3-tap a waterline into the END OF THE PIPE LIKE RIVAS with a valve to adjust water flow

    always want to have the option of letting it run the way it was designed too( no water taps) hence the valves.

    your not included in this Steve since these are mostly your ideas.LOL
    dang, i can't participate in this mod. Lol I personally think the 1/4 inch pisser holes will do the trick with some water injection before exhaust exits to thru hull. you new I wouldn't stay quiet! LOL

    The only problem with drillling the pisser holes is that there is no way to adjust it.

    This is the exhaust tip I have with 2 3/8 holes in it for the water to go into the exhaust tip. I just use a T valve to adjust the water flow. This has a bunch of holes in the exhaust tip. We use to do this with a 3/8 brass fitting. We would braze it up then put a slit in it like a pressue washer tip to make the water come out in a fan spray right before the exhaust exit on the race skis to make them more quiet.

    It has been almost 18 years. I know it was at least a couple of db, since the the ski was going to get DQd because we forgot to turn on the T valve to let in the water and it was too loud. When we turned the water back on then went back out it was within the limit.

    anyone have a pic of the drilled out pisser? are you talking about just drilling out the existing hole to 1/4"? that will bring it down a few DB? I got the rotax box.. almost the same thing as the shorty, no? DOnt want to draw attention from the police who sit 200 feet outside the swimming area and watch my beach. LMK
