A tilt mechanism for a marine outboard drive includes a hydraulic cylinder assembly disposed transversely offset from the center axis of the tilt mechanism. The tilt mechanism includes a swivel bracket carrying a drive unit for pivotal movement about a generally vertically extending steering axis and a clamping bracket supporting the swivel bracket for pivotal movement about a generally horizontally extending tilt axis. The swivel bracket has wall portions transversely extending from the steering axis. One of the wall portions positioned nearer to the hydraulic cylinder assembly is reinforced greater than the other wall portion. Also, the clamping bracket comprises a pair of spaced members. One of the spaced members positioned nearer to the hydraulic cylinder assembly is reinforced greater than the other spaced member.
A tilt mechanism for a marine outboard drive comprising a swivel bracket carrying a drive unit for pivotal movement about a generally vertically extending steering axis, said swivel bracket having wall portions extending generally transversely at both sides of said steering axis, a clamping bracket supporting said swivel bracket for pivotal movement about a generally horizontally extending tilt axis, said clamping bracket having a pair of transversely spaced members adapted to be affixed to the transom of an associated watercraft, said wall portions of said swivel bracket at least partially being capable to be fitted between said transversely spaced members, a hydraulic cylinder assembly being capable to expand and contract along its longitudinal axis, said hydraulic cylinder assembly having a pair of end portions, one of said end portions being pivotally connected to said swivel bracket and the other one of said end portions being pivotally connected to said clamping bracket, said hydraulic cylinder assembly being biased to one of said transversely spaced members, and at least one of said wall portions and said transversely spaced members positioned nearer to said hydraulic cylinder assembly being reinforced greater than the other one of said wall portions and said transversely spaced members.
