I agree with the battery discharge factor - but you'd surprised how much trickle you can get from a solar charger - definately enough to keep the cells happy. A lot of these mains "battery savers" only kick out a couple hundred mA, whereas the solar ones will make 150-200mA easy.
Venting is needed on a Lead Acid one at all times, really - plus there is the splashing issue on a boat - inside a box or not.
You might want to look at something based around a split charger circuit, so the one battery won't drop below "death" levels. I've seen something for car batteries when the car is left laid up for a long time - will self disconnect when down to a preset level (something like one last start) - google for "battery brain" - basic unit is from about £20-odd.
How much current does this motor draw? Seen some cracking little devices based on the old fag lighter socket, but only allow 10A..
