Looking for some advice on impeller selection for the stock pump.
If anyone remembers my build thread from 2years ago I built an fx1 for my son. The hull was in the process of a 144 swap when I got it, but against my better judgment I decided to put the stock pump back in it since I didn’t want to buy another sj pump setup and I had everything for the stock one and it was less work. At the time he was 9 and like 55lbs. We got busy, had another kid and were racing moto and hadn’t ridden for over a year and a half.
Fast forward to now and we have been riding again, he didn’t miss a beat and now that he’s a little bigger and stronger he’s ripping pretty hard. I put him on my ski which he didn’t like before and he was riding it way better than his just because of the extra horsepower and hookup.
His ski isn’t terrible once it’s going but it cavitates pretty bad in the whitewater and it just doesn’t have that instant hookup to unweight the ski when you need to. I can ride it fairly well but you are pretty limited on what you can do without the hookup.
Current setup is: 62t/62t, stock pipe, r&d intake grate and a solas 17/23 cutback 2mm
@Sparkplug is nice enough to hook me up with a protec pipe that I can make work for it so that will help a little with the power department.
I know not allot of people run the stock pump but for those that have does anyone think I can see an improvement with a different impeller? My stock pump fx1 experience is riding the one I had back in the day once before stealing the motor and bpipe out of it and giving away the hull. I will eventually do a kawi pump swap most likely but if I can get it working better with an impeller I will try that in the mean time.
Thanks for help.
