Hi, I'm new to the site and really enjoy all I've read so far. I live in Kansas and have 19' grumman. It has a little top rail damage from getting swept downstream in a flood one time. Anyway I'm wanting to put a motor on it, probably something in the 8hp range. one of the forums mentioned that the grummans twist and over time will develop cracks. Should I beef mine up? Anyone done that and have pictures of what they've done? Thanks.
