SS Prop for Johnson 115 - 4 Stroke - Year 2004

[MNUser]

I know some are already running this motor with a SS prop, so I have a couple of questions.

The boat is a 2004 Explorer SS 1700. Dual console, not that it matters.

Here is what is on the motor:

13 1/4" - 19

Here is the SS prop I have been looking at:

13 1/4" - 19

Rapture XHS

Stainless Steel Propeller for Johnson, Evinrude 115 HP

(4-Stroke 15 tooth spline)

$184.99

With the prop that is already on the motor, the boat runs 6000 WOT and runs about 40 MPH. It performs well. The hole shot is good. Kinda slow with three in the boat but acceptable.

Can a person switch out with SS and have the same overall RPMs? What else should I know? I would purchase on-line so it would be a pain to exchange. I have heard all about the try before you buy idea. I have searched and found other posts regarding the same motor but have yet to find one that brings the discussing to some sort of conclusion.

Thanks for helping.

you can expect the ss prop to help with cornering and speed but I would suspect you will lose about 200 or so RPM by going stainless in the same pitch and diameter. This is due to less flex in the blade. What you may find (and this is a good thing) is that with the steel prop, you can probably raise your motor up a hole...probably two holes which will help gain those RPM's back. Going higher with the motor will make the boat more efficient too, which increases fuel economy, and may help hole shot (this sometimes can do the opposite too with different set-ups) Overall, you would be getting more motor and boat out of the water.

I'd go for it with the Rapture, test it out to see how things work, then start raising the motor up to get the rpm's back. Could end up being a good 45-46mph boat when you are all done.
