    I wondered about that wedge. I"ve heard that it can cause over stuffing even with the RXP hull. I also read that it wouldn't give any gain at all. I planned on testing it with my RIVA plate to satisfy my own curiosity. This makes me want to try it even more. I don't want to get bucked off at 80mph either. Does anyone know why the pump wedge is not recommended with the RIVA plate on the RXP. Hell if it safe to run and will and adds speed I'm game.

    Not trying to hijack your thread. Just want to offer another suggestion. I want to see how fast that ski or yours will go. Please take a look at the pics I've attached. I noticed with the install of my RIVA plate the grate hung down alot lower that with the OEM plate. I removed some material from the mounting surface of the grate to make it sit flush. How does your grate look? While I can't give a back to back comparision because of the weather conditioin we've been having here I suspect that there may be additional speed to be gained here.
