Systems and methods for automatically draining marine drives at multiple trim angles

A method for automatically draining a marine drive at a plurality of preset trim angles less than a fully trimmed out angle, the method comprising:

• receiving via a controller a request to drain the marine drive;
• operating a trim actuator via the controller to change a trim angle of the marine drive to a first trim angle among the plurality of preset trim angles;
• waiting a first preset time after the marine drive is trimmed to the first trim angle;
• and
• operating the trim actuator to change the trim angle of the marine drive to a second trim angle among the plurality of preset trim angles that is different than the first trim angle, wherein the marine drive is configured to drain when trimmed at each of the first trim angle and the second trim angle, wherein changing the trim angle to the first trim angle, waiting the first preset time, and changing the trim angle to the second trim angle all responsive to receiving the request prevents operator error and provides consistency in automatically draining the marine drive, wherein the powerhead of the marine drive comprises an internal combustion engine, further comprising cranking the internal combustion engine for a preset crank time and controlling the marine drive to prevent the internal combustion engine from starting while cranking to assist in draining the marine drive.

A method for automatically draining a marine drive at a plurality of preset trim angles less than a fully trimmed out angle, the method comprising:

• receiving via a controller a request to drain the marine drive;
• operating a trim actuator via the controller to change a trim angle of the marine drive to a first trim angle among the plurality of preset trim angles;
• waiting a first preset time after the marine drive is trimmed to the first trim angle;
• operating the trim actuator to change the trim angle of the marine drive to a second trim angle among the plurality of preset trim angles that is different than the first trim angle, wherein the marine drive is configured to drain when trimmed at each of the first trim angle and the second trim angle, wherein changing the trim angle to the first trim angle, waiting the first preset time, and changing the trim angle to the second trim angle all responsive to receiving the request prevents operator error and provides consistency in automatically draining the marine drive;
• and
• detecting that the marine drive is not operating before changing the trim angle to the first trim angle, wherein the powerhead of the marine drive is determined to not be operating by detecting that a key is in an off-position.

A method for automatically draining a marine drive at a plurality of preset trim angles less than a fully trimmed out angle, the marine drive being coupled to a marine vessel, the method comprising:

• receiving via a controller a request to drain the marine drive;
• operating a trim actuator via the controller to change a trim angle of the marine drive to a first trim angle among the plurality of preset trim angles;
• waiting a first preset time after the marine drive is trimmed to the first trim angle;
• operating the trim actuator to change the trim angle of the marine drive to a second trim angle among the plurality of preset trim angles that is different than the first trim angle, wherein the marine drive is configured to drain when trimmed at each of the first trim angle and the second trim angle, wherein changing the trim angle to the first trim angle, waiting the first preset time, and changing the trim angle to the second trim angle all responsive to receiving the request prevents operator error and provides consistency in automatically draining the marine drive;
• and detecting via a sensor a vessel angle of the marine vessel and operating the trim actuator to adjust for the vessel angle when changing the trim angle of the marine drive.
