[QUOTE="CedarRiverScooter, post: 440052, member: 15465"] My 1st try had the intake grate pretty much flush with flat bottom - you can easily guess how much that cavitated. The next winter I cut it back apart & lowered the intake are about 1.5 inches. I fabricated a tapered panel, kind of like a vee, to make the transition. It worked great. Another change I made was to remount pump angle to fix porposing. If I recall correctly, you have a mod V hull, so that should push air to the side well. Theat polaris 750 should push it to mid 30 mph. Edit: I tried the 'top loader 'grate, if that is what you are referring to. It helped with cavitation but allowed big rocks in, bad for the impeller. I still have but have no use for it - it's yours for the shipping if you want it. [/QUOTE]
