20 foot tri toon w/115... is it enough?

#1 Post by mikeb33 » Sun Sep 23, 2018 6:50 am

I currently have a 2008 Sweetwater 2386 rfe with Yamaha F115. It has (2) 25.5" tubes, lifting strakes and under skinning. Empty I have hit 28 mph, more like 24 with a bunch of people.
Looking for a new pontoon with a few changes. I'd like a different layout, no carpet, an easier to put on mooring cover, and more performance for tubing and such. Yesterday I saw a 2018 Bennington 20SSRCX triple tube that would get a 115 hp. It's a little smaller but I think it's big enough for my group. I wonder about the performance of it? Originally I figured my next pontoon would have a 150-200 hp, but this one being smaller and a triple would it move pretty good? Thanks.

Honestly, it sounds like you have the numbers and the experience to make the decision of what is good for you. If your main criteria is more "more performance", I would be thinking more horsepower because your boat scoots along pretty good already. "More performance" is pretty broad.

My neighbor here at the lake wasn't happy with his 33 MPH, pontoon so he upgraded - by buying a smaller boat with more HP.
Now he's not happy with 44 MPH, so he is looking his third third boat with an even bigger motor.

I realize that people have different needs, so MY opinion of "good enough performance" may be radically different than yours.

My Durango has 350 HP and my son's Civic has 174 hp and accelerates faster and turns sharper. I just thought a smaller triple with the same power should be noticeably more "sporty"? Sporty enough? How do you know? I'm sure it's big enough anyway. It says max 11 people. I've had 13 on mine, but often it's just me and the wife or another couple. At those times a 23 footer seems ridiculous.

Look at the capacity plate and see what the max HP it's rated for. If it's 115 and you like the layout, go for it. If the max rating is higher, always get the most powerful motor you can. Even if you aren't interested in top end, a boat with a bigger motor can typically run more efficiently at lower speeds than the same boat with a smaller boater.


Horsepower is like a TV. I never hear anyone say they wish they had a smaller motor or a smaller TV! :biggrin2

I am a 24' Bennington owner. Do yourself a favor and go a 22' or longer boat with a 150 hp motor. They are much more seaworthy, and the 150 hp motors are substantially stronger than 115 hp even on a shorter boat. The 22' may not be that much more $ than a 20' boat, but you'd find it much more comfortable of a ride.

I test drove a new 22 tri toon with a 150.
If you want better than 25-28 mph and want to pull tubes, I do not think the 115 is going to do it for you.
115 would be great on a 20 for easy cruzin and relaxing, but your not going to get "performance".
I am the guy at the boat ramp that gives you dirty looks when you are a complete idiot and too stupid to know it.

all the 150's of any make are much bigger displacement than the 115's and much faster all through the rpm range.

Its the best 2 to 3 grand or so you can spend on a motor. 5 to 7 mph faster easily.

I have a 22 with a 150 it does 43. My dad has a 2 tube same brand with a 90. It does 26.

I have a twenty foot tri toon with a 2016 Yamaha 115 on it. While it is no speed demon, it certainly is more than adequate for pulling skiers and tubes and gets out pretty decently. It's also very sea worthy as I often take it 10 miles or more out in the Gulf of Mexico. Sure, a 150 would be nice, but my boat tops out between 28-38 mph depending on the load and water conditions. The fuel economy is great and the boat sits pretty even in the water with the 115. A 150's additional weight is going to drop the rear a fair bit when placing the bigger motors additional weight on a 20 foot boat. I wouldn't want anything bigger than a 20 footer, I couldn't imagine dealing with a 24ft or bigger pontoon boat. 20 foot is plenty for me and the family/friends space wise.
