Re: Looking at a new pontoon tomorow need a speed question answered thanks
I have a 2012 18' party barge. I opted the biggest engine the transom would allow, a 75hp 4 stroke. I can run 24 mph with a 13 pitch prop at wide open. I agree with Jeepman, go for the biggest motor you can get, you can always throttle back. The 18 to 20 mph you will get with that 60 hp won't give much of a thrilling tube ride.
Good Luck!
