I'm thinking about a tohatsu 20hp for my 1648 grizzly. It's got a trolling motor, 2 batteries and gas tank, nothing else weight wise. Mostly me and sometimes another person. Y'all think with the right prop it would plane? I'm not looking to go fast, 20 mph tops. The trolling mtr has a quick disconnect mount so if I use it duck hunting that weight plus the battery weight would come out.
