A service door for a cowl for a marine propulsion device. A door panel is positionable in open and closed positions. A first hinge rotatably couples the door panel to the cowl. A coil spring biases the door panel towards the open position and a damper resists rotation of the door panel towards the open position. The first hinge rotates about a first axis and has a first hinge base, a first hinge axle, and a first hinge axle opening that receives the first hinge axle. The first hinge axle has base and distal ends. The base end is coupled to the first hinge base and the distal end has a spring slot. The coil spring has fixed and rotating ends. The rotating end imparts a spring force on the door panel with the fixed end in the spring slot.

Service doors for cowls on outboard marine propulsion devices

A service door for a cowl for an outboard marine propulsion device that includes a door panel that is positionable in an open position and in a closed position. A first hinge rotatably couples the door panel to the cowl. A biasing device operates in conjunction with the first hinge and biases the door panel towards the open position. A second hinge rotatably couples the door panel to the cowl and at least one of the first hinge and the second hinge provides only one shear of rotation between the door panel and the cowl. A damper operates in conjunction with the second hinge and resists rotation of the door panel towards the open position. The inside of the cowl is accessible when the door panel is in the open position and inaccessible when the door panel is in the closed position.

Service door for cowls on outboard marine propulsion devices

A cowling for an outboard motor has port and starboard intake ports that direct flow of intake air into the cowling and extend downwardly along the aftward side of the cowling and face laterally outwardly. A duct system receives and conveys intake air intake ports to an intake conduit for the outboard motor. The duct system includes port and starboard intake troughs that extend alongside the intake ports and redirect the intake air from a generally lateral flow into the intake ports to a generally vertically downward flow and then to a generally forward flow towards the intake conduit. Port and starboard baffles that extend alongside the intake ports and direct flow of water into port and starboard channels located alongside the baffles, respectively. The channels drain the water by gravity depending on tilt and trim orientation of the outboard motor.
