Depends on what size boat you looking to get! I have a 1436 with at 25 hp on it. Fished out of this boat for years and love the little boat. I have minn kota 40lb thrust and it has all the power you need. Now as for the battery dont over think it but dont get a car battery either it will not hold up the the charging and discharging. Best bet is to go to walmart and get the biggest deep cycle marine battery they have. usually a group 27 or so! Being a small boat I dont see you having the need to have a on board charger so any multi setting charger will work just fine can probly find it at wally world to! With my boat I can go 6 or so hours pulling cranks and thats a constant on the battery!
