Everstart is a private brand name for Wal-Mart and is not actually the name of the manufacturer. Some Everstart batteries are made by Exide and some by Delphi Automotive. Both good companies.
If you use the battery to run an electric trolling motor, you should use what they call a "deep cycle" marine battery and not an ordinary car battery. "Deep cycle" in this case means you frequently run the battery all the way down to a discharged state and then charge it all the way back up again. Ordinary automotive batteries have a pretty short life time if you treat them this way.
If you just use the battery for starting an outboard, running lights, etc. then you could get away with using a car battery with no problem.
As has already been mentioned, if you have 2 or 3 batteries connected in your boat, you should replace them as a group. Also, do not mix marine batteries in together with automotive batteries.
P.S. I am NOT connected with Wal-Mart in any way, heaven forbid.
