Thread: Prop ?

  1. #1

    Default Prop ?

    New to boating and need advise and help? I run a 22' Searunner with a 115 Yahmaha, The current prop is in OK condition but I was given a Brand new prop from a friend who had it on his Yahmaha 100 (his motor blew) any how my prop does not have a stamp on it but do have a pretty beat up spare that has a #s stamped on the inside 17K, Y-3, 6E5, the new one given to me is stamped 15K, Y-2, 6E5 with a 13 1/2 X 15K on the outside.

    My question is can I use this Prop, is it safe? Thanks for any and all inputs

    What is your current running rpm, mainly wot? The 15 pitch will run 500rpm higher than the 17p you re running. My target rpm is 55-5700rpm at wot on my F115.
    The emphasis is on accuracy, not power!
