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.

I have same boat (2000 model) and have 2000 30 HP Mercury 2 stroke and it will run about 30 with just me and my gear. I always have "just in case" items with me, so my gear may weigh a little more than most. Fun little boat that is applicable for most lakes/rivers in TN, albeit underpowered for my liking on the big river (MS River).

I've got a 1548 with a 25hp. I did change the prop, but it will do 31 with daughter and I.
It don't have a pad, so I don't think it actually "planes out", but it gets up on top of the water just fine.

If a boat is rated for a 40 put a 40 on it. If it's rated for a 400 put a 400 on it. I've never heard anyone regret maxing out the HP but I've heard many many people complain that they went cheap and underpowered their boat. I hunted with a buddy this past weekend that has a 1648 that's rated for a 40 and when he bought it he put a 25 on it. He regrets it every time he gets in the boat.
