Hello all,
I have a 1994 Freedom 35' with the Yanmar 3GM 27 HP engine and optional feathering "Max Prop" which is ready for a rebuild or replacement. Does anyone know what the diameter + pitch for the standard fixed 2- blade or the Max Prop 3- blade?
Thank you.

Re: F-35 Propellor Specifications
Not sure if this will be of much help, but here are some specs as noted on original Max Prop brochure. Someone delineated the numbers below:
Definitely have a three-blade Max Prop. 16" diameter was circled on original spec sheet/brochure as though that is my prop. Will ask SF Boat Works if they have documentation on blade settings. Prop was sent back to be refurbished.
Further notations were:
18" blade angle = 9.8 prop pitch (in inches)
14" blade angle = 7.6 prop pitch (in inches)
Right rotation (clockwise for forward operation)
18" x = E, y = H (11/99)
14" x = T, y = B (2/100)
The axis info refers to letters that surround two slotted hubs. Each is set to desired. Assume the numbers are a counting of the slots (or degrees?) in lieu of letters that might be worn or illegible?
Without better explanatory background info, it is all Greek to me.
What I do know is the boat powers along great and everyone that has been at the helm has remarked about the good 'traction' in reverse. Being a rookie, very glad to have the prop dig in and pull me out of mistakes steerage.
