Systems and methods for raising and lowering a marine device on a marine vessel

A system for a marine vessel operating in a body of water, the system comprising:

• a trimmable marine device coupled to and movable with respect to the marine vessel;
• an actuator configured to raise and lower the marine device relative to a surface of the body of water;
• a control module in signal communication with the actuator;
• a global positioning system (GPS) receiver that determines at least one of a current and a predicted global position of the vessel;
• a processor that accesses a memory storing bathymetry data and retrieves a water depth corresponding to the at least one of the current and the predicted global position;
• and
• a sensor associated with the actuator that provides information related to a current position of the marine device to the control module;
• wherein the control module compares the water depth to a depth of the marine device based on the current position of the marine device;
• and
• wherein the actuator raises the marine device in response to a determination by the control module that the water depth is not enough to accommodate the depth of the marine device at the current position without potential collision between the marine device and a bottom of the body of water.
