Method for controlling the tilt position of a marine propulsion device
First Claim
1. A method for operating a trim system for a marine propulsion device, comprising the steps of:
- providing a sensor which is configured to transmit a first signal which is representative of a position of said marine propulsion device;
causing said marine propulsion device to move to a desired uppermost trim position, said causing step comprising the step of responding to a manually caused actuation of a switch by energizing a hydraulic cylinder to cause said marine propulsion device to tilt upwardly relative to a marine vessel, said switch being disposed on said marine propulsion device;
receiving a second signal which is indicative of a change in a monitored condition; and
storing a magnitude of said first signal when said change in said monitored condition occurs.

Abstract
The calibration procedure allows an upward maximum limit of tilt to be automatically determined and stored as an operator rotates a marine propulsion device relative to a marine vessel with a particular indication present. That indication can be a grounded circuit point which informs a microprocessor that at calibration procedure is occurring in relation to an upward trim limit. When the ground wire is removed or disconnected from the circuit point, the microprocessor knows that the calibration process is complete. During the rotation of the outboard motor or marine propulsion device in an upward direction, both the angular position of the outboard motor and the direction of change of a signal from a trim sensor are stored.
