Here's what I now have:
- Old two log 24' pontoon boat with outboard
- Use it mostly for family outings on a medium size lake (tubing at WOT, cruising a mid-throttle)
- Engine is 2015 Mercury 115HP 4-stroke with Command Thrust gear box
- Current prop is 4-blade aluminum 14.8" diameter with 15" pitch
- Max rated RPM is 6000
- WOT with just me yields 24 MPH (GPS) at 5300 RPM
- Slip calculator says that is 27% slip
- WOT with 1,000 pounds of people and gear is 20 MPH at 5000 RPM
- Slip calculator says that is 33% slip
- When looking to gain RPM and decrease slip, which if either is more important, pitch or diameter?
- Between the 14x14 and the 14x16, which would you recommend to meet my goal and why?
- Are there other reasonably priced propellers you'd recoommend over the two I mentioned.
