I have a Pontoon rebuild project that I'm about to start and I'm toying with the idea of adding a center pontoon. Has anyone done this before? If so, was it worthing it.... performace, any gas savings??? Did you modify your trailer??? I found a place that will sell a 10' center log with motor mount that will extend 18" from the back of the boat. This would set the motor back from its current position about 15". The company stated it will add 650lbs extra floatation to the rear of the boat. They also sell a 15' center log, would that be better? My current boat is a 20' bass buggy DL Looking for anyone's input on this.
