Abstract: A stern drive system having an outdrive rotatable about a generally horizontal axis to impart a desired trim or tilt to the drive system is provided. The system includes a gimbal ring that defines an inner region. The gimbal ring is configured to pivotally receive a first anchor pin. A tilt-trim assembly is affixed to the outdrive, and the tilt-trim assembly has one respective end thereof configured to pivotally receive a second anchor pin supported by the outdrive. The assembly includes a single cylinder through the inner region of the gimbal ring and has one end thereof connected to the first anchor pin so that when the cylinder is actuated the outdrive is rotated about the generally horizontal axis.
