    RPX-X Waterbox Mod

    Ok I am going to do a thru hull exhaust and mod the waterbox. I checked out the waterbox modding thread and it is pretty straight foward. I cut the end off of my RXP-X's water box tonight and of course it is different. There is no longer a baffle plate. There is was seems to be like a false floor on the bottom that starts in the front of the box (closest to the motor) and goes about half way to the back of the box. So where should I cut this box short? Also does anyone know if the Riva thru hull kit will work with the exhaust outlet on this box? I have removed the IC and I'm going to relocate it. I am trying to save myself some work. Here are some pics of the waterbox.
    Thanks

    My parents use to have a place very close to you on bayshore and 10th street. Now we are right next to sea tow. You have may a have seen my dads boat around. We boat there all summer. I want to shorten and gut the waterbox.

    yep i know the boat, you guy have a nice setup there next to seatow.
    i'd be spending my summers on that boat, skip right over the seadoo
    i only got a 03 gtx sc or a xpdi, puttin in a greenbox at the moment, so i cant comment on waterbox for the RXPX.
    but i would think it will be same procedure as for the previous year boxes
    just drill your thru hull in the RIVA location so if any other new versions of greenbox come out you will be set.
    are you familiar with older rxp or rxt exhaust setups and shorty boxes??

    somerear exhaust kits utilize the stock box configuration, while others use a shorty box, which has the exhaust exit pipe to teh rear of th box.
    take a pic of the side of the box, with the 2 pipes sticking out th top, so we can see what we are working with and how it compares to boxes of previous years.
    the old j pipe used to come into the top of the box at an angle, this one looks like it comes in right thru the front weld on the top of the box??

    beachbum, there is nothing to gut out of the box. I would leave that false bottom alone if I were you, you know what that's for right?
