I was on the lake Saturday and at one point, the battery felt like it was dead when I tried to start. The battery was a little old but I had charged it the night before. I bought a new interstate battery on the water and it helped. At first, it still turned over really slow, like with a dead battery. Then after a while, it just started fine. The next day, after again being on the charger, it would sometimes do the same thing. Act like the battery is dead and then all the sudden turn over fine. Sometimes it would do this during the same key turn. It would barely turn over like 6-8 times and the spin freely.

So my question is whats going on. Is it the starter going bad? Something in the electrical system not giving the starter enough power? Is it something worse?

Thanks for the help
