Will a SS prop from a 1991 force 150 hp 13 1/4 X 19 pitch # on hub p695 ,15 spline fit on a 1999 force 120 hp?And does a SS prop make much of a difference as compared to an aluminum one?
without my prop book here I can't tell you on the prop fit, but I believe it will fit, but if you dropped from the Fab-5 to a 120hp, it's likely too much pitch.
Does SS make a difference over alum??? Heck yea...if ya set it up right.
