dear friends, I have a problem, I have a motor the 115 Johnsons slp of four cylinders of year 1998 mounted in a Triton tr17 of he himself year desire to know as it is the measurement of the support then if he is 13*1/2*20 or 13*1/4*20, I do not hope podais to help to a greeting from Spain thanks
Buenos' Dias Ismael,
A 13 1/2" diameter propeller will be a 4 blade renegade style, a 14 1/4" will be a 3 blade Raker style propeller. The Renegade will be an odd size pitch 17, 19 21, inch pitch, The Raker will be an even size 20",22,24". To try and answer your question, a 3 blade will give you more "top end" and a 4 blade will give you better "hole shot". You want to keep your motor in the upper end of the RPM range, so don't get a pitch too large to keep your motor from "lugging". I would try a 14 1/4 X 20" Raker or a 13 1/2" X 21" renegade. Set the motor height so the center line of the nose cone on the lower unit is 3 1/2" below the pad of the boat.
dear friend thank you very much by your aid from Spain but my problem it is that propeller has cleared me and not that diameter is if is 13 1/2 or is 13 1/4, the motor is johnosn 115 (J115TSLECM) of year 1998, the axis or internal arrow has 13 grooves but if he is 1/2 or 1/4 I am not expected you can help thanks and Merry Christmas
I guess I lost something the the translation of the question. Are you talking about spline count of the prop shaft or the actual diameter of the prop? An aftermarket propller will offer a prop hub kit to fit a OMC/BRP product. Any OMC/BRP prop will fit your motor only thing you will need to do is change the thrust washer between a Raker and a Renegade, dpending on your model year.
