    GPRXP or GPRSHO

    I have tried searching through the forums trying to find a thread comparing the two with speeds etc.
    People i talk to at pwc performance shops where i live say sea doo's/RXP's break down all the time, but ive read nothing but good things about GPRXP's on here.

    Welcome to the GH forums.

    A gprxp is nothing more than a RXP using a gpr hull, or if it makes you feel better, is nothing more than a GPR using a RXP engine. There are about a gazzilion different versions, and every one is going to have varying degrees of reliability and usefullness. Some are show queens. Some are down, and dirty racers. Some are all-around performers. Some are drag boats.

    I think you get my drift. Trying to compare a GPRXP to a GPRSHO is an absolute waste of electrons. You can't even compare two seperate GPRXP's.

    Quite frankly, I've only seen a HANDFUL of pwc-performance shops that would have any idea about either one of these, much less both of them.

    The SHO engine is still rather new, and undeveloped. The Rotax is getting a little long in the tooth, but has a ton of aftermarket behind it. Both are exceptional powerplants.

    The SHO motor sounds absolutely nasty, I dont like the sound of the RXP motor...

    other than the sc washer failure, which can be prevented, the rxp has exceptional reliability.

    The only flaw of the 4-tec engine was in the valve train and that was worked out after 04.

    GPRXP seems easier to build and cheeper. Just my 2 cents but maybe I am biased due to I have built 4 of them...... (GPRXPs)

    It's a lot easier to find a RXP/RXT motor than it is to find a SHO motor. Much cheaper too
