With the weather breaking some, Im finally getting to check out all of the things on my new (to me) 1986 Sylvan Deluxe 24' pontoon. This boat has the gas tanks and batteries that sit behind the rear wall on a small platforms, with the motor in the middle. The previous owner built locking storage boxes for theft protection. After I paint them, the will look pretty good. My question is this....He has a gas tank and battery in each one. One box has the engine starting battery with gas tank, and the other one has the deep cycle battery for accessories and the spare gas tank. Is this safe, or should I move them to wear the batteries and tanks are stored in the same compartment.
