Haven't opened it up yet, but thought that she would be a bit faster at this RPM. Is this speed about right for 4000 RPM based on how she's powered? She also has a T-top with a glass top.
So far I like the way she rides just need a bit more time to get out and run her, put her through the paces. Appreciate any comments.

If you keep the boat light you might be able to swing a 19 pitch. My 23' with an F250 runs 30 mph at 4000 RPM, burning 9 or less GPH, turning a merc revolution 4 blade. I rebuilt my boat light and rarely have more than 55 gallon on board, so she is fast. But with two full tanks, 3 guys, gear, and 100+ lbs of ice and fish the fuel burn goes up only a little.
I would try a 19 4 blade if i were you, you might even be able to raise the motor a notch
