    I have a RXP 155. The best performance mod for the dollar looks like the Solas 11/19 impeller. Does anybody have experience with these and are they worth it?

    What's the stock pitch on the 155? If the 11/19 is a bigger prop its going to hurt you unless you get more power out of the motor.

    according to that website. I'm guessing the impeller I have is the same one as the GTX NA. This means my impeller would be 10/21. So how does the 10/21 differ from the 11/19?

    If you install the riva water box you dont need the riva rear exhaust kit. You only need the thru hull fitting and coupler.
