A system and method control a trim device that positions a trimmable marine apparatus with respect to a marine vessel. A trim system is operated in an automatic mode, in which a controller sends signals to actuate the trim device automatically as a function of vessel or engine speed, or a manual mode, in which the controller sends signals to actuate the trim device in response to commands from an operator input device. An operating speed of the propulsion system is determined. When the operating speed has crossed a given operating speed threshold, the trim system is subsequently operated in the automatic or manual mode depending on whether the operating speed increased or decreased as it crossed the operating speed threshold and whether the trim system was operating in the automatic or manual mode as the operating speed crossed the operating speed threshold.

1. A method for controlling a trim device that positions a trimmable marine apparatus with respect to a marine vessel having a propulsion system powered by an engine, the method comprising: operating a trim system in one of an automatic mode, in which a controller sends signals to actuate the trim device automatically as a function of one of a speed of the vessel and a speed of the engine, and a manual mode, in which the controller sends signals to actuate the trim device in response to commands from an operator input device;determining an operating speed of the propulsion system; andin response to a determination by the controller that the operating speed has crossed a given operating speed threshold, subsequently operating the trim system in one of the automatic and manual modes depending on: whether the operating speed increased or decreased as it crossed the operating speed threshold; andwhether the trim system was operating in the automatic or manual mode as the operating speed crossed the operating speed threshold. 2. The method of claim 1, wherein the operating speed comprises one of the vessel speed and the engine speed, and wherein the operating speed threshold comprises one of a vessel speed threshold and an engine speed threshold. 3. The method of claim 2, further comprising determining with the controller if the operating speed crosses one of two given operating speed thresholds, and if so, subsequently operating the trim system in one of the automatic and manual modes depending on: whether the operating speed increased or decreased as it crossed the one of the two operating speed thresholds;whether the trim system was operating in the automatic or manual mode as the operating speed crossed the one of the two operating speed thresholds; andwhich one of the two operating speed thresholds the operating speed crossed. 4. The method of claim 3, further comprising defining at least four operating zones of the propulsion system based on at least two engine speed thresholds and at least two vessel speed thresholds. 5. The method of claim 4, further comprising: defining a near-idle operating zone that ranges from a first engine speed threshold to a second engine speed threshold;defining a normal operating zone that ranges from the second engine speed threshold to a third engine speed threshold;defining a near wide-open-throttle operating zone that ranges from the third engine speed threshold to a fourth engine speed threshold; anddefining an overspeed operating zone that ranges from a first vessel speed threshold to a second vessel speed threshold. 6. The method of claim 5, wherein: the first engine speed threshold is an engine idle speed;the second engine speed threshold is a calibrated engine speed;the third engine speed threshold is a given percentage of a maximum rated engine speed;the fourth engine speed threshold is the maximum rated engine speed;the first vessel speed threshold is a calibrated maximum control speed of the vessel; andthe second vessel speed threshold is a maximum achievable vessel speed. 7. The method of claim 5, further comprising restricting the trim system to operation solely in the manual mode in response to a determination by the controller that the propulsion system is operating in the overspeed operating zone. 8. The method of claim 5, wherein when the propulsion system is operating in the near wide-open-throttle operating zone, the method further includes one of the following: operating the trim system in the automatic mode in response to an on/resume command input via the operator input device; andoperating the trim system in the manual mode in response to an override command input via the operator input device. 9. The method of claim 5, further comprising operating the trim system in the automatic mode in response to one of the following: the propulsion system transitioning from the overspeed operating zone to the near wide-open-throttle operating zone; andthe propulsion system transitioning from the near wide-open-throttle operating zone to the normal operating zone. 10. The method of claim 5, wherein a boundary between the near-idle operating zone and the normal operating zone is further defined by a third vessel speed threshold, such that both the second engine speed threshold and the third vessel speed threshold must be exceeded in order to transition from the near-idle operating zone to the normal operating zone. 11. The method of claim 10, wherein when the propulsion system is operating in the normal operating zone, the method further comprises operating the trim system in the automatic mode in response to one of: an on/resume command input via the operator input device; andthe engine speed decreasing below the second engine speed threshold and subsequently increasing above the second engine speed threshold and the vessel speed decreasing below the third vessel speed threshold and subsequently increasing above the third vessel speed threshold. 12. The method of claim 1, further comprising determining with the controller if a current trim position of the trim device exceeds a given trim position, and if so, at least temporarily disabling the automatic mode and maintaining the current trim position of the trim device. 13. A trim system for positioning a trimmable marine apparatus with respect to a marine vessel having a propulsion system powered by an engine, the trim system comprising: a trim device having a first end coupled to the vessel and a second, opposite end coupled to the trimmable marine apparatus, the trim device being moveable to adjust a position of the trimmable marine apparatus with respect to the vessel;a controller selectively controlling the trim system in an automatic mode, in which the controller sends signals to actuate the trim device automatically as a function of one of a speed of the vessel and a speed of the engine;an operator input device selectively controlling the trim system in a manual mode, in which the controller sends signals to actuate the trim device in response to commands from the operator input device; andan operating speed sensor sensing an operating speed of the propulsion system;wherein, in response to a determination by the controller that the operating speed has crossed a given operating speed threshold, the controller subsequently operates the trim system in one of the automatic and manual modes depending on: whether the operating speed increased or decreased as it crossed the operating speed threshold; andwhether the trim system was operating in the automatic or manual mode as the operating speed crossed the operating speed threshold. 14. The trim system of claim 13, wherein the operating speed comprises one of the vessel speed and the engine speed, and wherein the operating speed threshold comprises one of a vessel speed threshold and an engine speed threshold. 15.
