    PORPOSING

    Would anyone mind chiming in on what can cause porposing on a RXP?

    I know OPAS is one, what are others? can it be the small gaps between the plate and hull or can it be the intake grate holes not being filled or can it be that your intake grate might not fit completely flush with your ride plate?

    What are some others? I seem to bounce at around 67 on up to 71 plus and if im not on dead smooth water I end up jumping out of the water slighty.

    I do have a worx grate, prop, ride plate holes filled etc etc etc etc.

    do you have a pump wedge? Does it help if you trim it down a couple of notches?

    The Riva Pro series blockoffs, or the RE B.O.'s eliminate all the porporsing.

    no wedge and to be honest I dont feel that it does. (the notches) Im just wondering if I need to silcone my gaps between the plate and the hull of if its something to do with my grate.

    Yes definatly fill in the holes and seal the rideplate..Not saying this will cure the problem but it wont hurt..If your proposing that bad then Go with the block offs first..If it still porposes after the block-offs are installed then look to the ride plate..If it is not set right it will cause the ski to porpose also..

    Great... Just had a new pump shoe installed so maybe the plate isnt set right. besides the porposing is there anyway to tell if the plate is not set right?

    Make sure the front of the plate is flush with the hull..If it hangs down some then it needs to get tucked up flush....Did it porpose before the shoe replacement??

    its actually tucked below the hull. Basically why I needed to fill the gaps between the hull and the plate. its about a 1/3 of an inch gap between the hull and the plate all the way around.

    Im not an expert with the ride plates but from what ive been told you want the front flush with the hull and tuck up into the hull the farther back it goes...So if it is below the hull in the front that very well could be some of the cause of your porposeing..MAybe someone who knows alittle more about the plate setup can chime in and verify if this is true..
