I would like to know if I should try this. I have had my 135 HO Etech for 1 year and now I want to upsize my prop. Currently running a mid range but want to go for the speed this year. What is the max peitch and boat speed (Aproximentally) for a 2015 Smopkercraft 172 XL Pro Angler boat?
These links will help you decide on a prop, remember that finding the best all around prop is trial and error

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
I'm running a Solas 14 3/4 x18 HR3 Titan at 5900 Rpms on a Mirro craft 1766 Dual Impact 52 to 53 mph. I think a 19 Pitch would be a little better for top speed as I'm on the upper end for rpms. It looks a we have very similar boats. You can buy 2 solas props for the price of one Evinrude prop.
