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.

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.

A connecting member of a universal connector includes a first insertion hole and a second insertion hole formed on from a first end surface toward a second end surface of the connecting member, and a third insertion hole and a fourth insertion hole formed on the second end surface toward the first end surface of the connecting member, whereby the insertion holes will not be affected by and damage other structures of the connecting member in the mechanical process, so as to achieve the enhancement of the convenience of processing.

A floating joint includes a driving side coupling portion and a driven side coupling portion serving as first and second connections. A pressure adjusting structure in the floating joint is provided between the bottom surface exposed region of the spherical portion for contact and the bottom surface facing region of a fixing ring without a gap, and has elasticity. Therefore, the floating joint relatively firmly maintains the one-side spherical contact relationship, in which the top region of the spherical portion for contact contacts a part of the bottom surface portion of the frame body by the elastic force of the pressure adjusting structure.
