Thanks for the prop calculator, and keeping me honest.
I miss spoke on my early post. I meant 5500 rpm.
I know the number still don't match, but I remember my GPS hitting 47 Kts (I always keep my GPS set to knots). Of course, that was 6 years ago, and I'm doing this from memory .
My boat was very light, I was still putting in back together, no windshield, no bench seat, and very little fuel.
With that 20P Powertech Prop, it was slow to get on plane, and at WOT, I had the motor trimmed way up. I only stayed at that speed for about 5 secs because the squirliness I felt made me uneasy. I made another run at WOT, and had the same result. I definitely remember thinking that this hull was not meant to go that fast
I traded the 20P for a 19P the next day, still didn't like the hole shot, and ended up with the 18P I run now.
That's my story, amd I'm sticking to it
