Alpha prop size

Anyone know if a 15 1/4" prop will fit on an Alpha?

Yes it will, my buddy has a 21ft 1987 Scarab 1 with a 260hp 350 with a alpha and a 21p mirage plus on it.

Maximum prop diameter on an alpha is 15".

A Mirage plus is a 14-3/8" to 15" dia prop.

I am running a 27P x 15 Hydromotive on my Alpha. It looks like a 15 1/4 would fit, but would not leave you much room for error!!

Mercury recommends a max of 15" for the Alpha. If you run something larger and the blades should happen to flex forward, from the thrust imparted on them under load, things may get ugly.
