ABSTRACT:
A marine propulsion mechanism is provided with a variable height mechanism for varying the height of the propeller relative to a boat. The variable height mechanism includes an input gear connected to the engine drive shaft and an output gear connected to an output shaft which is adapted to drive the propeller. An idler gear is disposed between the input and output gears, and is movable about the input gear. A link is provided between the idler gear and the output gear for fixing the center-to-center relation of the idler and output gears, so that rotation of the idler gear about the input gear is translated into upward and downward movement of a movable housing portion to which the output gear is connected, and thereby the height of the propeller.
