[QUOTE="CedarRiverScooter, post: 382174, member: 15465"] Well, it's good to know that there will always be some cavitation in heavy chop. I may have set my bar too high. I am on hull revision # 9 or ten, lost count. Here is my latest concept (just a prototype). [ATTACH type="full" alt="spork.jpg"]73754._xfImport[/ATTACH] More of a spork than a spoon. The foam is just glued on with silicone seal. Believe it or not, it has survived 1/2 hour of running at high speed. It works great in flat water, & pretty good in today's 2 inch chop. The worst of it is cavitation in hi speed port turns, but not so bad when turning starboard. Must have something to do with the rotation of the impeller. I am going to proceed with a permanent version; will be treated lumber core with epoxy fiberglass skin. Glue & screw mounting. The other functions are pretty well fixed. She is running 6300 WOT, got the carb problem fixed (it was my bad on a pop off spring placement). Thanks guys, for all of your help on this. [/QUOTE]
