    you can cap off all the water exits you like, but it will not increase the amount of water going into the waterbox.... remove the j-pipe and locate the tiny like 1/8 or 3/16" pin holes in the bottom lip of the j-pipe... thats your water flow to the waterbox ... so if you cap the water line on top of the j-pipe u'll jsut increase the water pressure and eliminate your ability to flush the ski after riding in salt water

    flooding the waterbox with more water however may hurt your hole shot performance

    The way I look at it you haveA bypas on top of the J pipe RIGHT? If you plug that bypas more water is going to go into the water box. I called RIVA on this today, and they sed yes more water will go into water box. They sed I would not whant to do this. They don't know I have my water box MOD and J pipe cut. This allows for faster E-vac of water.
