Abstract
A method is provided for controlling a marine propulsion trim system under two distinct modes of operation. A first mode operates hydraulic cylinders at a slower speed when the associated marine vessel is being operated at a speed above a predetermined threshold. For example, when the marine propulsion device is under load, such as when the marine vessel is operating on plane, the first mode of operation is used and the trim/tilt cylinders are operated at a slower speed. A second mode of operation is used when the marine propulsion system is being operated below a predetermined threshold. In other words, if the marine vessel is operating at a slow speed, the faster mode of operation is used. Similarly, if the marine vessel is being prepared for transport on a trailer, the very slow or non-existent speed of operation of the engine is used as an indicator which causes the second mode of operation to be employed.
