I Brought a 2016 Yamaha FX Cruiser HO new. I like to slalom and barefoot ski. My goal is a better hole shot with less cavitation while staying off the rev limiter. A top loader intake grate is the only performance enhancement at sea level. It pulls hard right up to the rev limiter upon take off until skier is up. If the RPM’s went higher would it pull harder or do you think I’m dealing more with cavitation? Either way, I’m considering a dual impeller system and need help with options and what to expect. I believe this unmodified 1.8 liter engine has enough power to do the job and think it should pull to end of its power band without “spinning out” when pulling a skier up. I’m looking for low end torque pump efficiency with top end speed not to drop below 60 mph. In the meantime, can the within tolerance stock impeller be bent a little without actually being removed from the shaft to get me by?
