Patent ID: 7594834

Claim:
A marine propulsion apparatus adapted to be mounted on a stem of a hull for propelling the hull, the apparatus comprising: a casing for supporting a propeller that propels the hull; a cover extending upwardly from an upper end of the casing and surrounding an engine that drives the propeller; an anti-cavitation plate extending transversely outwardly from the casing for reducing a cavitation phenomenon generated in association with rotation of the propeller; a stay disposed above the anti-cavitation plate, said stay being attached to the casing and extending rearwardly from the casing; and a lift generation plate supported by the stay at a position rearward of the casing and above the anti-cavitation plate and extending in a width direction of the hull for generating lift during the propulsion, wherein when said hull is stopped, said stay is entirely submerged below a water level.
