32 mph is what the 10x13 SS calculates to at WOT at 6000 rpm and 7% slip.

I have that prop also, and got 29 mph at 5700 with 2-200 lb adults aboard. That calcs at 11% slip. But I have not yet adjusted motor height. It is running with AV plate in the water, so I expect an increase after I raise it. I have not clocked it running solo as of yet.

The 10x10 4-blade is a Solas Titan HR 4. With only 10" pitch, I thought it was doing well at 25 mph.
