Thanks Jared for the info that really helps know what to expect of the 150 4s. I have tried all kinds of props for the 115. The 115 has limited props compared to the larger gear case 150. I have even tried the lower ratio gear lower unit of the 75hp opti.It has a maxxum 80 trolling motor that i may change out to a 12volt 55 for less weight and lose a battery. I love the layout and the quality of the boat but the hull is not very forgiving of weight. I guess im use to a multiple step boat that carries weight better.John
