ABSTRACT:
An outboard motor includes a drive unit and a bracket assembly mounted on an associated watercraft. The bracket assembly includes a swivel bracket carrying the drive unit for pivotal movement about a steering axis and a clamping bracket supporting the swivel bracket for pivotal movement about a tilt axis. A hydraulically operated tilt unit tilts the drive unit with the swivel bracket relative to the clamping bracket. A fluid pump pressurizes a working fluid within the tilt unit. A relief valve relieves pressure that is applied to the working fluid when the pressure exceeds a preset magnitude, and an adjustment mechanism is provided to adjust the preset magnitude.
