Stock prop 11x13 no jack plate hit 5800rpm & 36mph (Scary fast to me)
Stock Prop, TH Marine Jack Plate - Bad news. Blowing out in turns, rough chop, etc. I never had the opportunity to run WOT.
Turning Point Props 11 pitch, TH Marine Jack Plate, 32mph, Very Punchy hole shot

5750rpms but Cavitation plate was only ~4 above transom.
Turning Point Props 13 Pitch w/ Proprietary Cup, TH Marine Jack Plate, Sluggish hole shot, 5400rpm, Cavitation Plate ~5.5" above transom, top speed 33mph.
I'm going with a custom built stainless 3 blade prop with a proprietary cupping once I get the setup dialed in. It's only (HA!) $310 for the custom prop which is still a lot of money, but for a prop tuned for my application and that costs about the same as an off-the-shelf model. Ya, I'm sold!
