83 harris/kayot

[bbdropshot]

I have a 1983 20' or 21' harris/kayot classic with a 305 mercuriser, it will run 41mph on gps at 4250rpm with a 19 pitch ss prop, just wondering what the max rpm is on that motor, and if i should go down in pitch for more top speed and rpm. It planes of good.

Usually there is a label on the motor.
