​Friend nicked a Yamaha SS 19P x 15 1/4 Dia prop. I have in my inventory a Yamaha SS 19P x 13 3/4 Dia. What will be the difference in performance??? This will be on a Yamaha 225 4 stroke.

Use the smaller one, watch the rpm's and send the SS prop in to be re-conditioned.

Yea you just have to see what top Rpms are. Engine rev limiter will kick in so it’s safe to use. What two props are they?

I’m guessing those two don’t have the same hub size. If they’re the same hub size and same blade design etc you’ll see 200-400 more rpms I would suspect

I am going to guess the saltwater is the 15 1/4 and the reliance is the 13 3/4
