Prop size and performance

[andrewsailor]

Anyone out there with an Alumacraft Classic 165cs with a 75 4 stroke motor,I'm just curious as to your prop size and performance
I'm 38 mph @ 5700 with a 13 x 19 prop
Thanks

Re: Prop size and performance

From my limited reading I would say your right about there.
You might check the vertical height of the motor.Raise it to a point just before venting(cavitation) becomes a problem.Most end up with the antivent(cavitation)
plate about 1" above the bottom of the boat.
