ABSTRACT:
A tilt/trim device for an outboard engine mounted on a transom of a marine vessel includes a stern bracket adapted to be fixedly mounted on the transom, a swivel bracket pivotally supported on the stern bracket, the outboard engine being adapted to be mounted on the swivel bracket, a hydraulic cylinder/piston unit for vertically swinging the swivel bracket with respect to the stern bracket, the hydraulic cylinder/piston unit having one end pivotally coupled to the stern bracket and an opposite end pivotally coupled to the swivel bracket, and a hydraulic circuit hydraulically connected to the hydraulic cylinder/piston unit, for extending and contracting the hydraulic cylinder/piston unit. The hydraulic circuit comprises a main oil tank for storing working oil therein, an auxiliary oil tank for storing working oil therein, the auxiliary oil tank being disposed in a position higher than the main oil tank, and a communication oil passage through which an upper portion of the main oil tank and a lower portion of the auxiliary oil tank communicate with each other, the communication oil passage being inclined upwardly from the main oil tank toward the auxiliary oil tank.
