I installed the Mercury black max, 15 pitch, 10.125" diameter (part number 48-73140A4).

Very noticeable improvement of maneuverability at the dock, the boat is now much more predictable and responsive vs the old 4 blade propeller.

With two people onboard, the boat would not get out of the hole unless I moved one passenger forward of the console and even that was slow. The old 4 blade 12 pitch would plane more easily, even with 4 people onboard. Once on plane, I did see nearly 28mph on the GPS. Had to keep 15-16mph to stay on plane. Cruised comfortably right around 20-21mph. Stable, no proposing but seemed more inclined to ventilate at higher trim.

The new propeller has solved my slow speed handling which is a big win but wondering if another option would allow me to plane more easily? By the way, I am still running the hydrofoil, would removing that assist with any of the conditions I mentioned? Thank you!
