Hi All,

I got a spare 3 blade prop with my 2nd hand 1993 Mariner 4cyl 40HP.

Its got these markings on it which I would like to know what they mean

On the body, between the blades
48 816706 A40 14P

And on the end where the spline enters, on opposing sides

one side an "A" and the other "25"

Any ideas out there [smiley=confused.gif] ??? ???

The one on the motor now has all the same except 12P on the end, I'm guessing its pitch.

cheers

you are correct the 12p is the pitch and if all other No's are the same you could assume the diameter is the same and therefore will get better holeshot and probabley about 500 rpm at WOT
