They aren't sealed, but the water level looks fine ...
and did you get the hydrometer out and check it?
Buy the 36 month full replacements and just take them back every 35
Make sure you drop it on the ground nice and hard before you return it.

If you are using deep cycle batteries for both starting the engine(s) and your boat's 12 volt electrical system (stereos, mood lighting, & other accessories) you are shortening the life of you battery.
If you want to run the accessories all day and into the early evening then you should consider installing a 2 to 4 bank battery system. With dedicated Starting batteries and House batteries (Deep Cycle).
Or one could buy Dual Purpose Starting/Deep Cycle
I buy the batteries for my boat at West Marine so no matter where I'm at Lake Mead, Havasu, the River, or San Diego if a battery goes - I'm back on the water in a few hours drive time!
