    What waterbox to use on GPRSHO

    Gotta a question gang!

    I am converting a GPR to a GPRSHO. I already have the modified exhaust and was wondering what water box setup should I use for a simple swap. Not going to be setup for all out speed but just a reliable fun ride. What do you suggest?

    Thanks for any tips.......

    this is a great alternative to stock water box if you dont want to cut it and gut it.

    no problem. remember for that waterbox to work its best to have the exhaust pipe modified. Bruce in the conversion skis for sale section has one already modified and ready to go at a very easy price. i just bought 1 from him i think he has 1 or 2 more left!

    A good alternative is a shortened 1200 box. I had posted this in a couple of other threads for those interested as well. This is what we ran we the ski was supercharged, and Ben currently runs it on his boat. It performs really well and sounds good also.

    if u want to use a stock box, u have to use a 1200 box, because a 1200 box does not have that square welded on it.
