I've removed the hydrofoil and went back out yesterday to re-test and get max RPM numbers. Boat performed largely the same without the hydrofoil, slightly more inclined to porpoise. Here is what I found:

-With three onboard, couldn't plane the boat even with throttle wide open and one passenger moving up to the very bow - I could get it to plane (but very slowly) with two all the way at the bow.
-With two people and throttle wide open, it will plane (again, very slowly) with one passenger moved to the very bow.

Ran wide open and trimmed out until the prop began to slip and then two taps back down on the trim. Reached 5200 RPM, max on this motor is 5500 RPM.

Your recommendations on where to go from here are greatly appreciated! I'd like to regain the ability to plane without a lot of load shifting and maintain the slow speed control at the dock that I'm getting now with this propeller. Thank you all in advance!
