The Ozutsu Outboard is a downloadable Racing Truck in MotorStorm RC. It is modelled after a rescue dinghy, particularly the ones used by the RNLI/Coastguard. The side of the dinghy reads "Adventure Raft".
The Outboard is available to download from the PlayStation Store for free, but for one week only. From then on, it will be a paid-for item.
