Pitch & Diameter for Prop
 

I have a 1996 Mariner 50hp 4 stroke motor. The prop has the following
numbers 48 827312A10 10.5P I believe the last set of numbers (10.5) is
the pitch. Is there anyway to tell what the diameter is with these
numbers?

Thanks

These are the props listed for a 1996 Mariner 50 hp 4 stroke.

DIA P

10-3/4 x 12
10-1/2 x 13
10-3/8 x 14
10-1/8 x 15

Just guessing, but it might not be an original. :)

Measure the diameter it probably the second best way to determine the
diameter.

The best is to just call a dealer and ask.

My guess.... the 10.5P is definitely the pitch. And the 10 after the A
represents the diameter, although it could mean anything from 10.0 to
10.99 (i.e. 10.25 or 10.50 or 10 5/8).

And I agree with Shorwave, the two best ways to find the diameter are
"measure it" (if odd # blades, measure radius then double it) or ask a
dealer (although I disagree on the order of "bestness) ;-)

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.

I would put Google in first order of 'bestness' and you will find :
http://www.marineengine.com/parts/pr...mber_prop.html search for
48-827312A10 on that page and then click check price for that entry to get
the size. It is a Mercury 12X10.5

CORRECTION 2 other sites found on the same Google results list show that the
prop size is listed as 11 5/8 x 10.5, thae all agree that it is a
Mercury part # so I would try a mercury link or dealer listing.

To each his own I suppose. -shrug- Personally, I'd still trust a
tape measuire over a dealer OR a website.
