Here's what I was thinking. I wanted to transfer some weight around in my 15 ft jon boat so I was thinking about moving the starting battery to the front under the deck, then I thought just maybe I could use a smaller motorcycle battery for the engine and leave it in the back to save money on wiring since wire would cost about 2$ a foot to relocate. I have a 25 horse evenrude. I was thinking that a motorcycle battery would work, since it will turn over an 88 cubic inch high performance engine. Any thoughts?
