A fishing buddy that knows a lot more than me about equipping a boat talked me into putting in a lithium trolling motor battery. According to him I will probably get close to 10 years out of lithium and even though the up front cost is high over a ten year period it comes out much cheaper that a common lead acid. Picked up the one below at a decent price and from the reviews I have read it should work out great for me.
Worked out great for me in the end, my dump trailer which uses a deep cycle battery was ready for a new one, so the old boat battery will go there and the old one out of the dump trailer will work great for my automatic clay pigeon thrower.
Now if it will quit storming around here I will get out on the water.
