Prop size help ?

[basstracker1970]

Could somebody please tell me what size this prop is ? It's off a 1983 Mercury 80hp inline and the prop is aluminum. On the side of prop I found these numbers.

48-77342-H10-15P

I figure it's a 15 Pitch prop but what dia is it???? Thanks a million in advance for any help.

Re: Prop size help ?

Is it possible that your Prop # is 48-77342A45?

That would be the Mercury part# for a 3-blade aluminum prop 13 3/4" X 15P to fit your motor.

Often times it can be difficult to read a part number after the props has been run for a period of time.

You could measure from the center to the tip of a blade and double the result.
Generally the diameter is a secondary consideration.If the prop is intended for your application
the diameter will follow.Also typically as pitch goes up diameter goes down, pitch goes down diameter goes up.
