A tilt-lock mechanism for a vertically tiltable outboard stern drive on a marine vessel preferably includes a hydraulic cylinder device dampingly connecting the drive unit and the vessel. The mechanism preferably includes apparatus allowing the operator to selectively prevent or allow the drive unit to freely tilt under various operating conditions.

In a marine vessel having a hull and an outboard drive unit carrying propelling means for propelling said vessel through the water pivotably attached thereto for movement about a generally horizontally extending tilt axis from a normal position wherein the propelling means is positioned beneath the water and a tilted up position wherein said propelling means is out of the water, a mechanism for damping the relative pivotal movement between said drive unit and said vessel about said tilt axis, said mechanism defining at least two fluid chambers and having restricted communication means for restrictively passing fluid between said chambers for damping the relative pivotal movement of said drive unit and said vessel, the improvement comprising fluid bypass means for selectively overriding said restricted communication means, thereby allowing free relative pivotal movement of said drive unit and said vessel about said tilt axis.
