I think my boat is a MAC 22, but I am not sure. I read or heard somewhere that the maximum capacity of outboard motor for these boats is 10HP. Can anyone confirm or refute that? I have a beefy motor mount that looks like it would hold a 10hp outboard w/o a problem. My concern is the motor I have is a 9.9hp Yamaha 4 stroke. Am I right to be concerned this motor might be too heavy? I am going to back up the mount with 1/2" plywood inside the transom and there seems to be plywood fiber-glassed in where the motor mount is located. I am looking for opinions...do you think I will be OK using this outboard or am I better off selling it and buying a smaller outboard. I do think the 9.9 is overkill on this boat but the trolling motor that came with it is underpowered.
