i HAVE AN 13 3/4 x 19 s/s PROP ON BOAT ABOUT RIGHT wanting to get spare prop and like the hustler prop line just wondering seems that 19 s/s is just about right for me thinking of 17' hustler for spare and have more bottom end for skiing but not sure if the hustler is like reg aluimium props and harder to turn than s/s.... been told that with reg aluimium prop need to drop 2" to turn same rpm as s/s if this is so then wouldn't want another prop of exact same character as one I have......any ideas.....
