If the battery is weak... replace it. No reason to get stuck out in the middle of the lake.
With that said.... just some thoughts on Batteries...
1) CCA is generally a calculated bit of data... so take it with a grain of salt
2) A regular load tester (that a shop may have) isn't a good way of checking things. Some engines need more POOP that others. We see it all the time, where a guy will say... "Well, I just had my battery tested, and the guy at the auto parts store said it's fine." WHEN... in reality, the battery is basically dead. Also... a shop CAN NOT tell you the reserve CCA unless they put the battery in a freezer, and do a real cold test on it.
3) A great "Home" test is to simply put a meter across the battery, and have someone start the engine. If it sags down below 11v... it's getting to be time for a new battery. a very healthy battery can stay at 12v. Some EFI system will refuse to start, if the voltage goes too low... but the engine may sound like it's cranking fine. (The 240 engine has that prob)
So... it's up to you. But for $100... you can have the peace of mind, that your boat will start, while on the water.

Not worth the plastic it's made from.
Sorry if that's harsh... but we've see SO MANY of the wal-Mart batteries that were either dead out of the box, or gave up a few weeks later... that they truly are CR@P !!! (Interstate batteries aren't much better) Who cares if they have a warranty, if they leave you stranded.
personally... I buy Die-Hard. They are a good price... and time after time, they have been proven to be better than some other "High-End" batteries. Plus... this time of the year... you can catch them on sale.
