How do I read Mercury prop numbers

[jkering66]

Hello,

I would like to replace my propeller on my 1988 Mercury 175.

Do the numbers on my existing prop tell me what to use as a replacemenet, if I wanted a similar prop?

Do theses numbers tell me size/pitch, etc, I assume the 15p is for pitch:

My prop:

On Back: 48-78116-15 (Or possibly 48-78|16-15)

On side: 48 78116 A40L 15P

Thanks

That is a 15? (dia) X 15 (pitch) prop.

It's a 15.25" x 15" 15P aluminum 3blade prop.
