So the new battery I bought is 2" longer than what was in the boat and doesn't fit the current battery tray. It appears that the one isn't stock because it looks excatly like the $6.95 versions on ebay. My father had a battery box laying in the barn so I snatched that. Two questions. 1) Any reason NOT to use the box vrs a tray? 2) It *looks* like the old tray is simply screwed to the bottom of the boat. To me this looks like a very BAD idea since I think the bottom of this is actually the hull. Better suggestions? See pic. Don't worry this will be nice and clean when I'm done with it.
