No matter what brand of battery you buy, the ultimate object of your selection should not be price, it should be the amount of reserve cranking you have in your battery. Although marine batteries are rated slightly different, (CCA vs MCA) the result is the same. It's a scale to let you know how much power your battery has.
In all cases DO NOT......EVER!!!.... use a regular car battery in a marine application. Automotive batteries are not made to withstand the deep drain/recharge cycles that the typical marine battery encounters. You can completely ruin a brand new automotive battery in as little as 30 outings on a boat.

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.
(Leave the rest to God) 
Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
