More endless prop talk...lol

Ok here goes. 22 ft G3 Suncatcher, 2 logs, no strakes. Yamaha 115 FB with 13 1/4 x15 stainless 3 blade cupped prop by Powertech. Hole shot is great, top speed at 5800 WOT is 26 m.p.h. Via GPS. We run WOT maybe 10 percent of the time , mostly cruising around 14 18 m.p.h. The reason for my post here is that while killing time I did the prop slip calculations and discovered that I currently am running at a slip rate of almost 38%. This top speed is with 4 aboard and half tank of fuel. I know this is a high number and am curious if it's worth looking into a change of props for what may be negligible improvement over current state. If there's little to be gained , it makes no sense. However, if there's a sizable amount of speed and performance to be gained, it changes the conversation. It's not that I am unhappy so to speak but at those numbers of slip it makes me think I may be way off on what my set up is vs where it should be...
I have ZERO interest in endless changes and trial and error as well as throwing money after ghosts. There's nobody around the Tulsa Ok area that will loan props to try so that option is out other than mail order and that's a hassle.
So here I am...at a crossroads. Need your input, folks. Like I said, more endless prop talk...lol Help!

Your doing good right now.
I would bet any type of change and you will lose top speed.
My best #s have been with a 3 blade stainless and my slip #s are just as high as yours.

I agree that you probably won't find much more speed but you could get more all around performance from a Yamaha/Turbo 14x13 pontoon stainless. Big 14" diameter + Big cupped ears = less slip. 13 1/4 diameter props should never be used on V4 case outboards on pontoons IMO. Typical 2 loggers can usually achieve under 30% slip with the right prop. I currently have a Solas Amita 4 aluminum 4 blade that I'm trying on my DF140 and its providing a very surprising amount of grip on the water for a 120$ prop!
