    What will I need to do?

    I have a 2004 RXP(yellow) that will turn a 14/19r at 8150 and 71.4 mph. I also have a Riva intake grate on it.
    I am wondering if I should buy an air intake or if it is worth it. Also if I do will I have to get my prop bent and how much. I don't even know of anyone who can do that up here.
    Any opinions?

    Rob, go with a custom 4" rear air intake or go with Riva's rear air. You will have to add 1 mm pitch to the prop, or go with a 15/20 depitched 2mm.

    What would I expect to gain from this mod?

    With the rear air intake you will probably gain 200 RPM's. This will put you on and beyond the rev limiter allowing you turn more pitch. With more pitch at 8100 RPM's will come more speed. I figure you would gain 1 - 1.5 mph with better accel.

    Yep, i can pitch that prop, or you might opt to buy the new 15/20 Solas i just listed in the classifieds that already has my pitch on it

    What are the chances of water injestion with that intake. I don't surf ride but I can get into some rough water in the Thousand Islands and Lake Ontario.

    boataddict i ride in some rough stuff also from time to time, and i havent had an issue so far, but i do run with the pre filter also just on the safe side and my engine compartement stays pretty dry but i do not sub marine it either.
    lake ontario does get rough would love to go back to 1000 islands again this summer.
