A testing device for testing a drive train or components within a marine propulsion system is provided and includes a first disk with a plurality of first disk depressions that faces a second disk with a plurality of second disk depressions. The first disk and the second disk are secured relative to each other so that they define a space, and a seal at outer edges of the disks is in fluid communication with the space. One of the first disk and the second disk is secured to a driven shaft. Upon rotation of the driven shaft, a load is produced due to shearing of fluid between the disks, yet no thrust is produced.

An outboard motor support device includes a transom connection mechanism, a pivot joint, and a motor support. The transom connection mechanism engages directly with a transom bracket to maximize stability and is configured to provide a consistently correct angular orientation of the motor support relative to the motor during use. In particular, the pivot joint adjustably aligns to the motor is a desired orientation during assembly to ensure a firm and “nested” engagement with the lower unit of the motor in the motor support. The motor support can be designed to fit specific motors, allowing for maximum stability and maximum surface area contact when properly aligned and engaged with the motor. The present outboard motor support device is formed as a single unit that provides vertical support as well as horizontal stabilization to the motor during transit, thereby also preserving the transom brackets and tilt/trim mechanism of the motor.

A cover structure of an upper unit in which a power source of an outboard motor is provided, the cover structure includes a main body cover including a pair of divided covers connected to each other, the pair of the divided covers being configured to be divided into each other in a left-right direction with respect to a traveling direction of a boat, and an attachable and detachable cover that is attachable to and detachable from a part of an outer surface of at least one of the pair of the divided covers.

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.

Apparatus and methods for transporting a marine outboard engine include securing a marine outboard engine to an engine support cart having a pair of rear wheels and a pair of front wheels, wheeling the engine support cart into a cage assembly, and mounting a removable dolly assembly to the cage assembly. The dolly assembly includes a floor-engaging wheel. The marine outboard engine transportation apparatus with the marine outboard engine secured within is balanced on the pair of rear wheels and the floor-engaging wheel when the cage assembly is tilted backwards.

The instant invention describes an anti-biofouling structure for placement onto structures or surfaces that are exposed to aquatic environments. Embedded within the anti-biofouling structure are agents that can diffuse out of the structure and prevent the formation and/or accumulation of plant and animal species build-up that creates biofouling. The instant invention also describes a system for preventing biofouling of an object stored in an aquatic environment which includes the anti-biofouling structure, and a protective cover element constructed and arranged to fit various structures, such as boat propellers.
