    It makes it easier to install the pump for me. I got big hands and there is no way i could get the pump back on the ski bymyself without it. Most of my modding is done alone.

    I have no idea as i have not ran without one. I think some here say it can increase top speed or afect cavitation.

    Maybe some will chime in with knowledge.

    Jerry said a while back that it is good for about 1 MPH without it. I had an issue with the prop nose cone pushing the driveshaft foward and causing extreme cavitation and causing the carbon seal to leak and almost sinking my ski so I run without one.

    This was proven at the higher RPMS..Guy running stage one and even some stage 2 boats didnt see any gain..so dont let this misslead you.If your running a riva ECU or rotax were your gonna see 8500 or better then this will benifit you performance wise...

    I had an issue with the prop nose cone pushing the driveshaft foward and causing extreme cavitation and causing the carbon seal to leak and almost sinking my ski so I run without one.

    This is a good reason to not run it at your mod level...If the cone starts to walk it will cause cavitation...IF your gonna run with out it make sure you put generous amounts of anti seize on the threads..
