    The early '03 models had a plastic pump. The later '03s and '04s have the aluminum pumps.There is no differance in the GTX the RXP and RXT pumps the only differance is the wear ring.There is no RXP or RXT prop that will fit the small shaft but the RXT shaft will fit the GTX them you can run the larger props just have to use the RXT and RXP wear ring.

    Rocketman, Thanks for the info. Im not understanding the above post can you please clarify? I thought the rxp.rxt used a larger drive and pump shaft no?

    The pumps are the same on all three skis. The driveshafts on the RXT and RXP are larger,but the RXT driveshaft will fit the GTX just have to use the RXT wearring and RXT prop.The RXP driveshaft will not work on the GTX because it is shorter than the RXT and GTX but the RXT and GTX will interchange.The end where they couple into the PTO housing is the samejust the prop end is different.

    I'm assuming that you want to put a 4tec pump on an XP. The basics of it are that you use a 2-stroke 155mm impeller modified to not hit the 4 tec pump body, threads are the same on the 4 stroke and two stroke pump shafts.

    can you use a rxp/rxt prop on a 2 stroke drive shaft? I did not think you could?

    What I want is a aluinum or stainless bodied pump with either broze,aluminum or stainless stator section I could use a 155mm 2 stroke impeller. Thanks

    read what I wrote again, you don't use the 4 tec prop because the driveshaft won't work. The 2 stroke impeller has to be machined some to keep it from hitting the 4 tec pump body. There is more to making it work than this but that's the big part.
