,,,wait just a minute Lance! I've got two blues on my trolling motor that so far are the best I've ever had! Now, they are only one year old but, so far have out preformed anything I've had before. {Interstates, 5 of them} I've never had an Interstate last for more than 18 months on my engine or trolling motor. I think I will need to replace my engine battery this year, another Interstate. If so I'm going to buy a yellow Optima. I was at Sears today and looked at their batteries. They were $189 / $239 on the big marine batteries for cranking or deep cycle!? We've all been on this battery thing before. The only thing else I would consider buying is the big Delco marine.
