4 BLADE VS 3 BLADE PROP

[CKJR]

i am running a 4 blade 14 1/2 x 19 blade on my 175 johnson 5300 rpms, if i was to change to a 3 blade, would the diameter be the same-any rpm changes?

Re: 4 BLADE VS 3 BLADE PROP

Depends on the brand of prop you have now and the brand you will get.<br /><br />Other than being a bit shy on rpm, why do you want to change? What brand prop is it? What year is the motor?
