Pitch & Diameter for Prop
 

Thanks for all your replies. I measured it and it's very close to 12".
And yes it is for a pontoon boat.

the pitch. Is there anyway to tell what the diameter is with these
numbers?
Thanks


As this is the OEM Mercury Black Max part number, it was originally a
10-1/2" pitch x 11-5/8" diameter. It may have been modified since then
if you are not familiar with it's history.

Oh, & I hope this is on a pontoon or barge - it's a pretty low pitch for
a 50hp MercMariner.

That's a good point.
