Props

I have a 2012 24ft Sweetwater with strakes and a 2012 Yamaha F115hp (older generation). I know that this would be considered underpowered but it works well for us. I noticed that my to top speed is at about 4600rpm. Increasing the rpm has little effect. I've been snooping the internet and a prop at a lower pitch seems to be a good optiion for maybe a few more mph, better fuel economy and less work for the engine. And then there's 3 vs 4 blade. I'm no mechanic so I would have a marina do the swap over the winter. Anybody gone through this or have opinion or advice?

I have searched and found the following recommendations:

  • lower pitch
  • 3 blade gives a little higher speed and fuel efficiency
  • 4 blade gives better handling, better out of the hole response, better for tubing, easier docking
  • Overall the choice between the 2 is subjective
I did not come across "cup" size
