I don't know Jim. If someone picks it up in the next few days, I'll let it go for sure. If not, then maybe I'll consider keeping it as a spare. My holeshot was terrible with this prop, and I'd like my WOT RPMs to be a little higher.
I don't know what the huge difference between out boats is besides the Permatrim and bottom paint. Could the Permatrim really make that much of a difference? How can it affect holeshot though?
Also, the replacement Powertech prop is giving me some very decent numbers. Similar to the Mirage Plus, but with a MUCH better holeshot. And the added stern lift is great.

Note: When I ran the Mirage Plus I had a little more fuel than when I ran the Powertech. Maybe another 25-30 gallons extra.
