    What's the good pump setup for a stock 03 GTX-SC?

    The pump in my 03 GTX SC seems to be completely goofed. I just changed the wear ring out and it's still cavitating so badly that it can't be ridden three up because it won't get on plane. I've heard that the 03 pump is just junk and needs to be replaced. So, what's the good replacement setup for one? 04 pump with a Solas prop in it? Where could I order one ready to slap in? Thanks.

    The '03 came with a plastic pump and it definately needs to be replaced with the aluminum one.They would not hold up to the horse power of the SC .I would suggest getting a pump and putting a dual bearing setup in it.It is cheaper than the stock parts and you will have a better pump. I have a stage one kit on my '03 and it would outrun my RXT when it was stock. I have the three blade Skat-Trak 155-83-23 Swirl 16\21 pitch prop and it is much faster than the 13\20 repitch that Riva sent with the stage one kit.
    I also get extra pumps from the dealer. They save me the damaged pumps and I send them to be reworked.
    I have one of these reworked pumps with a dual bearing and I will put wear ring and stock prop in for $500 if you are interested.
    I also have one of the plastic ones that came in them that is the housing only you can get real cheap if you want it.

    Sounds cool. Is there a better prop to run with a ski than the stock prop?

    I like the three blade Skat-Trak. The mods I have on it are the R&D air intake the R&D grate,2 1\2 degree wedge and O.P.A.S. removed so it is not to many mods and I GPS 67 consistantly.I did have the vortech impeller in it but I took it out and put it in my RXT.I had started with the 13\20 repitch from Riva but I was only running 65 with that prop.

    Just talked to PPG and they said $700 for a whole new pump with a Solas prop. Anyone know what kind of performance that will yield? Where to get the Skat prop?

    Glen should be able to get the skat-trak impeller for ya. Or you can order one from R&D I think. For that matter, skat-trak will sell direct also.

    Thanks. Is the Skat a 3 or 4 blade prop?

    What about mods for this ski? Are there some basic good ones?

    I think it's a three blade impeller.

    Jarrett; I can also order you a Skat 16/21 for your GTX SC...$199, but if you trade it in for another RXP, you won't be needing it.
