    1200 stx-r upgrades

    hello fellow water lovers , i have a few questions to ask.... i am the proud owner of an 02' 1200 stx-r and am looking for a few low budget ideas for going a little faster. everything on my ski is bone stock except for the plugs (ngk iridiums) i am willing to spend about $1000.00 any help for 4-5 mph's would be great. thank you all in advance for your help Bruce

    If you dont mind how much did you pay and what area are you in....

    Compression boost is always a nice bump in performance milled stock head or after market.

    Aftermarket heads and modding the carbs helps. Then look at getting the pump bluprinted and shimmed. That should get you started.

    The stxr and ultra 150 both use shims to adjust impeller clearance to the wear ring. You want it as close as possible .006-.008.

    I cant say for sure on the rideplate I have an ultra the shredmaster is the hot setup on it. As for the heads and pump skiworx would be good since you are on the east coast they are in MD.

    it's a modified stinger section of the pipe along with water injection.... skiworx does this mod and from i have seen it does wonders from this boat.... i would say 66 on a decent day with 1/3 tank of gas just to keep the nose from bouncing around
