finding the right prop

[bumpdraft]

I had a 15x15 prop on two different Johnson engines(235 and 200hp) before getting a 225 Yamaha 2 stroke for my 23. I put on a 14"x 19" prop and it made it feel like a different boat. It was fine for flat seas, but I didn't like the ride when it got rough. I eventually got a 15 1/4x 17 Saltwater series and was very happy with the prop. I changed to a Yamaha 225 four stroke with that same prop and I was only able to get 5400 rpm. I have since changed to a Solas 14 1/2 x 15 four blade and can get 6100 rpm. I should probably have a 17 " pitch, but it will do for now. I'm saving my Saltwater series, hoping to get a 250 four stroke.
