I use a regular group 24 marine starting battery. When I go to Tomahawk, it lasts for an entire week of boating. I ‘ve got to the point that I now leave my battery charger at home. The down side to this is the extra weight of a full size battery, but with the battery placed near the transom, I doubt you could notice any decrease in speed vs. using something smaller. I just like having the reserve cranking power in case of trouble. Having said that, there are many different 12 volt batteries out there that will work. I have one in my John Deere 318 that’s in between a lawn and garden battery and say, a smaller car battery. I forget what model # that battery is, but it cranks an 18 hp Onan with no worries.
Be sure that whatever you choose is mounted securely in the boat, and inside a marine battery box for short protection. A loose battery falling over in an aluminum boat is a bad thing!
