Number of Splines Alpha One 140hp?

[Jacalore]

I was given two props, both in great condition, for use as a get-home prop. in case of damage to primary prop, to keep onboard. Both are smaller than my prop, which is okay, but the number of splines is 13. Does anyone know the number of splines on a standard 14x19 prop for Mercruiser Alpha One 140hp sterndrive? For some reason, and I can't verify it online, I think my drive takes a 15 spline prop. Anyone know?
Thanks.

Too small, 'n the ventilation will be Bad, 'n the boat won't go,...

I believe All the standard Mercs are 15 spline,... even the outboard props that are Too small for an Alpha,...

my A1 is 15.. I too have seen props for sale with 13 tooth spline.. OMC sterndrive 1970's-80's,, and Asian Outboard motors mostly can be 13, not A1....based on what I've read about... if your A1 it's 15 teeth...

Can't find it on line? It's right here in the prop section.

You left out Johnson/Evinrude outboard motors(not V-6). They use 13 spline props.
