FYI, I run a 23p PM for a fishing prop on my 20XDC with a modified 260 hanging off the rear and a 26p PM for Summer Play.
After a Summer of both and running many times I've checked the prop slip which is positively Excellent on these props!
Runs were mostly made with just me, 1/2 tank of fuel, nothing in the well but all my fishin gear!
I'm totally impressed with these ProMax Props!!!
