What prop are you using now and what is you WOT rpm? Looks like your right at 41 knots.

I got lot's of different numbers based on tide direction and wind. It's so hard to find a clean place to run without variables that affect what your trying to find a baseline for. The lowest fuel burn at an average cruising speed is going to be the best indicator for propping. Top speed is a dragon everyone seems to chase but in reality the best mpg with an average loading is what needs to be nailed down.

Finally ran the boat after the 20hr service and raised the motor all the way on the transom. Hit 6K RPM's for the 1st time with the 18.5 prop. I was at 48 mph at 6K with 3 people and 1/2 a tank. My slippage is only 6% according to Mercury's calculator. Looks like I'm dialed as much I am going to get dialed! Put about 65 miles on her yesterday.

Jonas had a good time handling her for half the trip. Personal auto pilot!

That sounds great Danny.
She will loosen up with more hours.
6% is a strong number.

That is what makes us smile.

That and replacing tanks and hoses...
