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.
Mark
My Freedom 36 with 3GM30 engine has a fixed 2 blade prop with diameter of 17 inches and pitch of 11
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.
