POWERTECH, plus 5 degrees trim, DAY1 5340 38
POWERTECH, plus 6 degrees trim, DAY1 5380 38.5
HIGH FIVE, plus 5 degrees trim, DAY1 5630 40.7
HIGH FIVE, plus 6 degrees trim, DAY1 5680 40.2
CYCLONE, plus 5 degrees trim, DAY2 5280 40.8
CYCLONE, plus 6 degrees trim, DAY2 5330 40.8
My old Merc 3B Black Diamond 14.5"x17P was looking pretty good until it cavitated real bad during a hot hole shot. My dealer provided Cyclone was pretty efficient & performed well, but still short on WOT RPM (it worked perfectly for Bushwacker). Note: At beyond 6 degrees trim all were virtually unsteerable.

Well the Enertia Eco has been hailed as the magic prop...
Interesting. Were all of those props of same patch and diameter?
I believe Bushwackers PT Prop is an ELE4 model, very different shape with more cup than the MQS making it more difficult to spin.
The MQS4 is a SS 4-blade, comparable to the Black Max but designed with towing sports in mind. I think they nicknamed it SkiMax or something like that. I think your required trim angle puts a lot of undue pressure on the prop and combined with the extra force of a wake boarder maybe lending some effect to the cavitation you've experienced. Sounds like you'll need an easy to turn wheel and a favorable rake. You engineers are gonna have to figure that one out
Good luck with the Enertia.
