Abstract
An outboard motor is for propelling a marine vessel in water and can be trimmed about a trim axis into and between a raised position in which the outboard motor is fully trimmed up out of the water and a lowered position in which the outboard motor is fully trimmed down into the water. The outboard motor has a hydraulic steering actuator for steering the outboard motor about steering axis and a reservoir mounted on the outboard motor and containing hydraulic fluid for the hydraulic steering actuator. A vent opening vents the reservoir to atmosphere and is located on top of the reservoir and closer to the back of the outboard motor than the front of the outboard motor so that the vent opening does not become covered by the hydraulic fluid when the outboard motor is trimmed into and out of the raised and lowered positions.
