I changed standard 23" prop out for High 5 21" ..... this gave far better acceleration without too much losing top end (as it's a cupped blade)

This runs at 4500 WOT and makes 46mph .... would probably go a few mph higher if I had flat water and could trim out (those figures are fully trimmed in)

The biggest issues was that although it had holeshot, it had awful bow rise ... I fitted SMART TABS, and that cured the problem with slight improvement in acceleration,m and definite improvement in straight line tracking, esp against a beam sea.

This old thread still kickin' around! I'll trade you my carb for your MPI. I'm still pulling grown men up with a aluminum 23' prop and three adults in the boat and I have never taken my carbed 4.3 over 4000rpm. Guess I need to break out the video cam. Nail that throttle man!

not sure about your reply - my post mentioned mine is a carb engine ...
It could NOT pull me up on a mono ski deep water start on standard 23" ally prop.
needed High Five 21" to do that.
