Hmmm...I think you should state it price vs quality. I have bought some of the cheapest batteries out there, Fleet Farm. However if I have any real battery stress I doubt they will holdup. I think they cost me maybe $68 each. A cheap, higher quality battery should cost yiu maybe $115.
Well went from Group 27 Batteries to Group 31, The Carver Battery Boxes had Group 27 But the Group 31 fit NO Problems. I went and spent some dollars on Sears Top of the line Die Hards Sealed Blue tops for both I spent $460.00 I was not going too cheap on the Lake Michigan! did the install on July4th! and had a bunch of people out on the boat Most of Friday, Ran on Battery 1 ONLY for about 3 hours of floating around....No Issues!
Hey Jim, I think that was a good idea. I have 3 - group 27 batteries in my boat and they seem a little under powered...yes the el cheapo Fleet Farm batteries They are ok for my situation, sitting at the marina all the time and trolling the rest.
I would think for a boat your size the next group up is a great idea.
Yup, I went 3 each 31's myself. I installed new main engine battery boxes on mine.
I have to figure out where to put the box for the genny. I have a few choices. When my boat was stored for 10 years, they never removed the batteries. Eventually, the battery for the genny split open from freezing. The wood underneath is shot from the acid, and I see no way to install new wood unless I could find somebody the size of a five year old to get in there.
Thanks

Don't if you ever got in there to replace the wood but a good idea is to cover any Batt. box surfaces with a layer of fibreglass this will protect the wood and make it much easier to clean up any spills. Of course if you go for gel cells $$$ this is not so much of an issue but still a good idea non the less.
