Best I can tell based on what Lord Skools found out from the number it is a 15 x 17 aluminum. I agree the gps was reading a steady 38-39 mph as soon as I was able to lift the bow a little. It really took off and got to 5600 rpm quick, I was impressed. Unexpected for the 1999 115 hp. That was two adults and 3/4 full tank. When I got into enough chop I had to back down cause the prop would ventilate on the uplift. So that is job one this winter. Drop that motor two inches so I can trim up a little more. Right now I can trim up just barely past straight up and down and the bow stays pretty level flat. So the prop is not pushing at an efficient angle to the hull. As soon as I got that bow up a couple of inches it flew and I could tell it had more if I got it a little higher.
