Abstract

An apparatus for adjusting positions of an outboard propulsion unit of a marine vessel comprises a jack plate having a jack plate actuator capable of moving the propulsion unit between raised and lowered positions and a swivel bracket having a swivel bracket actuator capable of pivoting the propulsion unit between raised and lowered trim positions. There is a control system operatively connected to the jack plate actuator and the swivel bracket actuator. The control system includes a first manual control which incrementally moves the jack plate an incremental amount each time the first manual control is actuated and a second manual control which incrementally pivots the swivel bracket an incremental amount each time the second manual control is actuated. Movement of the propulsion unit within a tilt range may be detected and the jack plate may be moved to a preset position.

First claim

What is claimed is:

1. An apparatus for adjusting a position of an outboard propulsion unit of a marine vessel, the apparatus comprising:
a jack plate having a mount for the outboard propulsion unit, the jack plate being mountable on a transom of the marine vessel, the jack plate having a jack plate actuator capable of raising the propulsion unit to a raised position and lowering the propulsion unit to a lowered position; and
a control system operatively connected to the jack plate actuator for controlling movement between the raised position and the lowered position, the control system including a first manual control which incrementally moves the jack plate an incremental amount each time the first manual control is actuated, the control system including a memory which stores the number of times the first manual control has been actuated and moves the jack plate a plurality of incremental amounts equivalent to the number of times the first manual control has been actuated.

2. The apparatus as claimed in claim 1 , wherein the apparatus comprises a plurality of jack plates, each said jack plate having a mount for a corresponding one of a plurality of outboard propulsion units, and wherein the first manual control causes the jack plates to move upwardly or downwardly synchronously, whereby a plurality of said propulsion units move the same amount when the first manual control is actuated.

3. The apparatus as claimed in claim 1 , further including a swivel bracket having a mount for the outboard propulsion unit, the swivel bracket being connected to the jack plate, the swivel bracket having a swivel bracket actuator capable of pivoting the propulsion unit upwardly to a raised trim position and pivoting the propulsion unit downwardly to a lowered trim position.

4. The apparatus as claimed in claim 3 , wherein the control system includes a second manual control which incrementally pivots the swivel bracket an incremental amount each time the second manual control is actuated and wherein the memory of the control system stores the number of times the second manual control has been actuated and pivots the swivel bracket a plurality of incremental amounts equivalent to the number of times the second manual control has been actuated.

5. The apparatus as claimed in claim 4 , wherein the apparatus comprises a plurality of swivel brackets, each said swivel bracket having a mount for a corresponding one of a plurality of outboard propulsion units, and wherein the second manual control causes the swivel brackets to move upwardly or downwardly synchronously, whereby a plurality of said propulsion units pivot the same amount when the second manual control is actuated.
