A battery mounting structure for a small watercraft is constructed and arranged
to improve turning performance of the craft and to provide waterproofing protection.
A vessel body 11 includes a hull 14, constituting a lower portion
of the vessel body, and a deck 15 for covering on top of the hull. An engine
20 is disposed in the vessel body 11, with a drive shaft 35 extending
rearward from the engine 20 for driving a propeller 30, and a drive
shaft supporting box 18 for supporting the drive shaft at the midsection
thereof. The inventive mounting structure is substantially centrally located, so
that the battery 53 can be disposed on the drive shaft supporting box 18.
