Prop recommends?

[shane23ss]

My brother just had a brand new 115hp Mercury with the "Command Thrust" lower unit, 2.38:1 gear, put on his late 90's 17.5' Nitro last week. Anyone familiar with anything around this combo for prop recommendations? He's being told pitches all over the place by the dealer and Mercury. He's Needing a starting point. Thanks

I have a 15 Z6 with 115 CT, I am running a 25 pitch fury. Running approximately 5900 RPMs at 53 mph. I have hit 55 a couple times in the cooler weather, not sure what the RPMs were though.

Thank you, that's exactly the type of info we're needing

I had no idea a 115 could turn a 25 pitch.
