Mercury Prop question

[andy j]

I am looking to find a spare prop for my 95 mariner 90 horse motor. If a find a mercury with the same pitch (13X19) will they all work, Do older ones work? What do I need to know? thanks AJ

I was told that with the mercurys that if the pitch is 19 then the diameter will always be 13 is this true I have seen some 14 1/2 diameter 19 pitch mercuiser. will these work to. Thanks

No Sir, diameter and pitch are 2 different things and can be of any brand or make.

14.5" might be too big for your lower unit, it will hit bottom of cavitation plate.

The OEM number for the 13x19 is 48-77346A4.
The nearest Michigan Wheel match is 031043.

Andy, along with looking for proper pitch and dia you'll need to match the hub.
The OEM number is Merc's part number for your current prop which is a aluminum 13x19 for a 1995 90 hp. Use that number to order an OEM prop or use it to cross reference an aftermarket prop such as Michigan Wheel.

Maybe I'm not understanding your question.
"If a find a mercury with the same pitch (13X19) will they all work," I'd say yes as long as the hub is the right size. Say your at a rummage sale and you see a prop with the dia and pitch your looking for. Depending on what brand prop there will be their part number or a hub code stamped on the hub. Unless you can cross reference all hub codes and prop numbers on the spot you can't be sure of what your buying. What will help you is to know how many splines your prop shaft or hub has.
