ABSTRACT:
A hydraulic trim-tilt system 15 for an outboard motor 10 includes a hydraulic trim-tilt piston-cylinder unit 16 pivotally connected to both the transom bracket 11 and the swivel bracket 12. Hydraulic trim piston-cylinder units 22 are mounted in the transom bracket 11. A pilot operated check valve 43 mounted in the piston 38 of one of the trim piston-cylinder units 22 serves to limit the maximum pressure in the system when the trim piston-cylinder units 22 have reached the end of their stroke.
