2018 Suzuki 115A on a 24 ft Lexington Pontoon...what prop size

[Old Yeller Boater]

I have a 2018 Lexington with a 115 suzuki. I want so switch to a stainless prop. I'd like to gain a little top speed, but mostly just for longevity and a good bite in the water. I pull a tube sometimes but speed nor maneuvering with that is a critical factor. With my wife and I on the pontoon it maxes at 25 mph (GPS, not speedo) at about 4800 rpm.

the motor currently has a 14x18 aluminum which was on it when I bought it. I'm having trouble finding a 14x18 stainless. should I keep looking for the 14/18 or is there a better size?

TIA...

Hi all....still looking for some help on this one. I've seen a lot of used 14.25 x 18's and wondering if that size would work and what effects it might have on my performance. Not looking for speed, just that it work well. Thanks!

there's a propping sticky on here that you should look at first.
3 blade, 4 blade?...it all makes a difference...
What is the recommended rpm operating range of your 115 suzuki?
I'm willing to bet that 4800 rpm is not recommended at full throttle....your lugging your motor.....
