  • Patent number: 10494967
    Abstract: A system for determining an oil amount in a marine drive includes an oil level sensor that senses an oil level in the sump and temperature sensor sensing an engine temperature. A control module for the system is configured to determine that the engine temperature is greater than a temperature threshold, and that an engine speed exceeds a speed threshold for at least a predetermined time period or that a throttle position exceeds a throttle position threshold. If both such conditions are met, and a threshold drop in engine speed to an idle threshold is detected or a threshold change in throttle position to an idle position is detected, then an oil level in the sump is sampled with an oil level sensor. An oil amount is then determined based on the sampled oil level in the sump.

  • Publication number: 20190361446
    Abstract: A system controls movement of a marine vessel near an object. The system includes a control module in signal communication with a marine propulsion system, a manually operable input device providing a signal representing a requested translation of the marine vessel, and a sensor providing a first distance between the vessel and a first point on the object and a second distance between the vessel and a second point on the object. The control module determines an actual angle between the vessel and the object based on the first distance and the second distance. In response to the signal representing the requested translation, the control module stores the actual angle between the vessel and the object as an initial angle and controls the marine propulsion system to produce thrust that will carry out the requested translation and that will maintain the initial angle.

  • Publication number: 20190248462
    Abstract: A system for maintaining a marine vessel in a body of water at a selected position and orientation includes a global positioning system that determines a global position and heading of the vessel and a proximity sensor that determines a relative position and bearing of the vessel with respect to an object near the vessel. A controller operable in a station keeping mode is in signal communication with the GPS and the proximity sensor. The controller chooses between using global position and heading data from the GPS and relative position and bearing data from the proximity sensor to determine if the vessel has moved from the selected position and orientation. The controller calculates thrust commands required to return the vessel to the selected position and orientation and outputs the thrust commands to a marine propulsion system, which uses the thrust commands to reposition the vessel.
