Suzuki df140a prop question

[Ali Bobba]

Today was the first time I ran/got numbers from my new prop recommended by Powertech. I had also consulted Ken with Prop Gods. 14x18 3 Blade SS LNR3. @5500 rpm I got 32mph, @6100-6200 I got 36mph with a full 60gal of gas and just myself. It probably touched around 6300 a couple times when fooling with the tabs/trim (limiter hits at 6500 for 2017 model). It was really windy so I'm guessing maybe with perfect conditions and a half tank I'd hit around 40mph? Now I'm questioning whether I stick to it for thats all she's got, or try the same prop in a 19 or 20P? With a half tank I feel I'll be exceeding 6200 easily? My boat is a 20 with a 2' bracket that also has one hole remaining I can go upon the motor... Any advise or opinions would be appreciated!
