Abstract
An outboard motor mounting apparatus for outboard motors that control the outboard motor propeller thrust line angle of attack through a larger range than is currently available in practice today, including afterplanes (hydrodynamic lifting surfaces) in order to create boat stern lift. The afterplanes move to provide lift with a trimmable hinged portion in combination with movement of the outboard motor propeller thrust line.
Claims9
An outboard motor mounting apparatus configured to provide increased outboard motor trim adjustment on a boat having a transom and an outboard motor, the outboard motor mounting apparatus comprising:
- a first mounting plate configured for attachment to the transom and having a first body with a first edge and a second edge opposing the first edge, at least two legs extending adjacent the first edge of the first body and at least one arm extending adjacent the opposing second edge of the first body, the at least one arm having a first elongate opening;
- a second mounting plate configured for attachment to the outboard motor and having a second body with a first edge and a second edge opposing the first edge, at least two legs extending adjacent the first edge of the second body and at least one arm extending adjacent the opposing second edge of the second body, the at least one arm having a second elongate opening;
- an axle configured to extend through the at least two legs of the first mounting plate and the at least two legs of the second mounting plate to enable pivotal movement of the second mounting plate relative to the first mounting plate;
- and
- a coupling configured to extend through the elongate openings in the at least one arm of the first and second mounting plates and configured to cooperate with the first and second elongate openings to enable the second edge of the second mounting plate to move toward and away from the second edge of the first mounting plate and thereby alter the trim of the outboard motor relative to the transom of the boat.

A vessel, comprising:
- a transom;
- and
- an outboard motor mounting apparatus to attach to the transom of the vessel, the outboard motor mounting apparatus comprising:
- a first mounting plate to attach to the transom and having a first body with a first edge and a second edge that opposes the first edge, at least two legs extending adjacent the first edge of the first body and at least one arm extending adjacent the opposing second edge of the first body, the at least one arm having a first elongate opening;
- a second mounting plate to attach to the outboard motor and having a second body with a first edge and a second edge that opposes the first edge, at least two legs extending adjacent the first edge of the second body and at least one arm extending adjacent the opposing second edge of the second body, the at least one arm having a second elongate opening;
- an axle extending through the at least two legs of the first mounting plate and the at least two legs of the second mounting plate to enable pivotal movement of the second mounting plate relative to the first mounting plate;
- and
- a coupling configured to extend through the first and second elongate openings in the arms of the first and second mounting plates and configured to cooperate with the first and second elongate openings to enable the second edge of the second mounting plate to move toward and away from the second edge of the first mounting plate and thereby alter the trim of the outboard motor relative to the transom of the boat.
