Aluminum boat?  There is no way I'd allow a wet lead acid battery on my aluminum boat.
never had a problem in any boat or other rigs,but I do take care of my stuff...

Then the Duracell SLI24MDC is a good, cheap, wet acid,  marine deep cycle.  Itís a group 24, 75ah.  They are about 45lbs and run around $110 each.  I believe Walmart carries them.  They should last you 4 or 5 years if you treat them right.  I have a set in my RV and they have served me well.

Next step up, I also own a set of SLI31AGM Ė Group 31, 100ah.  They weight about 65lbs and go for about $250.  Very good batteries and being AGM, you donít have the acid spillage issue to worry about or contain. 

The very best lead acid deep cycle Iíve ever owned is the GC2-XHD-UTL.  I run my cabin on a pair of them, they are 7 years old and are just now starting to show their age.  232ah and they weigh a ton.  I think they were somewhere around $200/each.  But they are 6V so you would need 4 of them.  Weight and volume probably make them impractical for a small boat.

Whatever you pick, you are going to get stuck with core charges unless you have a trade in.  I think they run about $40 per battery.

two 27s in parallel. This 12v last all day. They sit in a milk crate at the foot of pass through. Being yours is 24V might lead towards 31s in series.

You meant to say in series not parallel.

I just have two Walmart brand 29 series deep cycles installed in battery boxes. They seem to work well for about 3 years and cost around 70$ each. Havenít had any of them leak yet but thatís what the battery boxes are for. Most importantly install an inboard two bank battery charger/maintainer and keep them plugged in. For maximum battery life and convenience. Minnkota sells a good plug. They can be found on Amazon or whatever. And the quick disconnect plate is nice.
