A marine drive unit with a bi-directional integrated oil channel

A drive unit for a marine vessel,

• the drive unit comprising an elongated drive unit body arranged to support a propeller shaft at a lower end and a motor interface at an upper end of the drive unit body, where the propeller shaft extends in a center plane of the drive unit,
• where a drive shaft is arranged extending from the motor interface through the drive unit body to a bevel gear arrangement arranged to rotatably connect the drive shaft to the propeller shaft,
• the bevel gear arrangement comprising a first bevel gear arranged on the drive shaft and a second bevel gear arranged on the propeller shaft to cooperate with the first bevel gear,
• the drive unit further comprising an oil channel arranged to allow a flow of oil to flow away from the propeller shaft through the drive unit body in direction of the motor interface,
• the oil channel having an input aperture comprising a first aperture part and a second aperture part arranged separated by the center plane and facing the second bevel gear,
• where when the second bevel gear rotates, the second bevel gear pushes oil up into one of the first aperture part and second aperture part,
• where the input aperture is arranged in connection to the second bevel gear such that an upwards flow of oil is generated through the first aperture part if the propeller shaft is rotated in a clockwise direction, and an upwards flow of oil is generated through the second aperture part if the propeller shaft is rotated in a counter-clockwise direction.
