I have a 115 outboard on a 20’ pontoon NOT tritoon. It seems no matter what i do with trim i cant get boat WOT past 22mph at 4700rpms. Everyone i talk to say it should go faster since no luggage and only 2 people but yet nobody can tell me what prop to switch to lol right now its a stainless 21 pitch
 
I have a 115 4 stroke on our 21' Bennington pontoon, 5900 rpm, 29 mph with a 13.5 X 15 pitch 4 blade aluminum propeller.
This is the prop I'm running. You would need a different hub kit for your suzy, since this one is for a Yamaha

Thank you. That’s almost pretty close to what another guy was telling me, but he said that doing it like that much makes it where it will redline and bottom out and stall alot unless stairing at the guage entire time. Thank you for the reply though I may try this out. The hub kit is no problem. I did it on my other boat and had no clue what I was doing lol but it worked.

My Yamaha is a 115 Vmax and the redline is 6300 rpm, I'm sure your Suzuki is probably similarly redlined. I'm happy with 5900 with two people, full fuel and typical light load. One thing I really like about this prop, it is fantastic at low speed maneuvering/docking, for a pontoon the boat responds well.
