I HAVE BEEN TOOLING AROUND AT 45-50 MPH ON THE LAKE AND WOULD LIKE TO KNOW IF IT'S POSSIBLE TO INSTALL A SUPERCHARGER. I THINK MY IMPELLER WAS CHANGED BY THE GUY I BOUGHT FROM BECAUSE IT POPS OUT OF THE WATER BUT I FEEL DOES NOT GO FULL SPEED. WHAT IS THE PROPER IMPELLER?

you cant just fit a supercharger as the s/c engines have lower compression ratio,forged pistons,ecu different and fuel regulator etc etc so dont even think about it, better to sell and upgrade to an rxt etc,
You can go to skat trak website and see what prop you should be using. What rpm do you get at full speed?

thanks for the reply, the max RPM is at 6500.

that sounds very low should have a 15/20 prop and run over 7000rpm is it running smooth may have a fouled plug but if it ranlike that after a prop change you probably have the wrong prop.

i guess my final question would be, does a prop change the RPM's

of course! its like the difference between driving in 3rd gear or 4th in a car its basically a final drive ratio as the pitch goes higher the revs go lower so higher horsepower engines need a higher pitch to keep the revs from going to high
