'14, 20' Xpress Catfish, 1261lbs. with Yammy 115....with a little chop, turning 5800-6000 RPMS running out at 45mph with about 450lbs of man meat in the seats...sound right? I know I have a lot to learn about trimming right but couldnt get it dial in very well with the chop but seemed like a lot of RPMs...here is the only marking on my prop.

WOT range is 5000 to 6000 RPM for your motor. Looks like you have a 13.50'diameter, 18 pitch, right hand rotation Power Tech prop. P/N is PTR3. You could back the RPM down a little with the same prop in a 19 pitch.

Its a ptr 3 blade right hand rotation 17P ym90 hub which is the yamaha. The top number is the serial number they use for tracking and warranty. For the load you are carrying the rpm's are just right. Youll have to back off the throttle a little when you are loaded a little lighter than you posted. If your tach is right then you are getting an excellent slip number out of that prop. I wouldnt change a thing. Keep it rev'ed up to keep the carbon cleaned out and she should live a long long time.

Thanks for the feedback, appreciate it!
