Do not worry too much about the dia.
The newer BRP props are 14 and not 13 3/4 as the old ones, but they fit.
Blade geometry however is slightly different and as a total a bit 'heavier' than the old ones.
Responds better to trim, but less stern lift.
If not replacing a prop with the exact same type and shape as the old one, always do a test run before final buy.
Any DECENT prop dealer will assist you with that.
