it's propped to run 150 MPH + and accellerates like a BEAST with these (size) props!!!!!! It has much, much more left in it. I believe we calculated 165 MPH (with stock motors). I know several folks have "turned-up" the rev limiters to 6800 or so, giving them substancial more speed (which someone who purchases this boat could easily have done if they chose).
We threw away the smaller "rough water" props and are solely running the larger. Throttle-up made this set to gradually increase in pitch as the blade moves farther from the hub and closer to the tip... 39's at the hub and 41's on the outer edge (16 1/2" diameter). This gives great holeshot to plane and HUGE accelleration to stay on top, pulling like crazy all the way North of the 150 MPH mark, with no "lag" to attain the last 5 or so MPH's, as do so many props of this pitch.
The boat is dialed in and ready for a turn-key owner ---- Now we're ready to begin the next one.
PS: selling a pair of 16 3/4 x 36's --- if anyone's interested, email me for pricing (pandakjoe@gmail.com).
