Will ther be any significant difference in performance between a 13 1/4 x 19 aluminum prop and a 13 1/2 x 19 stainless prop both being oem props?

Forgot to mention that both of these props are for a 70 hp 2 stroke Yamaha on a 15 foot Striper.

Yes....SS is way stiffer than alum and will give a better top end and holeshot but probably drop your rpms about 100 or more. OEM Yamaha should be a 13x19 SS.

This is an OEM prop and it is 13 1/2 x 19 - K from a 90 hp Yamaha.
