I/m pretty certain that anything bigger in diameter than a 14.5 inch is too
big for the alpha leg. Look at the clearance between your current prop and
the plate above it. On all the ones I've looked at a 14.5 is pretty close.
I think a 15 might fit but I'm not thinking a 16 will.

I don't know that I'd put much faith in web prop calculators. Most people
change based on what prop they have and what is wrong with it. In your case
you are overpropped and probably need to go down about 4 inches in pitch.

That's odd. The Mercruiser web site is the one that recommended the
16x14 prop after I plugged in all the specs. Are you sure it won't
fit?

I'll do some more research. I'm going to see if I can find anybody
local that can do a try before you buy toward a prop.
