I have a 2009 rxt-is. My impeller is starting to get damaged a bit. I want to put a performance 1. I believe solus is good right? Which size shall i use. I want it to have more speed off the line. Someone mentioned here that i can install a wedge pump also so the trim is like higher. I know my ski is a heavy 3 seater, but is there a way that when u give gas, it feels like a 2 seater. I like how the 2 seater, the trim is higher so it launches high when u accelerate. Any feedbacks would be great. I am new to this. What does it mean when it says Solas 15/22R? What is the diff?
