Our pontoon is set up with a single 225 Honda and will do 55 mph with the top down. What do you like to do with your boat ?
Sounds like a blast! Pontoons are really popular here. Great for fishing, beaching and pulling kids on a tube.
Top speed for me is about 38 to 40 depending on how much weight on board. But, cruising is really what the boat was for. Best thing I liked was pulling into a cove and rafting out with other freinds for the night under the stars...Fully self contained in AZ during the hot summer and cool winter seasons makes pretty much year around boating. An Expensive habit!
