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

Dont know...measure the diameter of the prop with a tape......

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.
