ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates generally to marine propulsion devices, such as outboard motors. More particularly, the invention relates to electrical and other harness arrangements for such outboard motors, and to rigging of such arrangements.
In the past, typical outboard motor rigging was found at many locations on an outboard motor. Many times the connections were low on the power head and were difficult to access and susceptible to corrosion. Also in the past, wire routing was often left to the person rigging the outboard motor, with the result that the wires were often routed in a manner which interfered with other components or caused chafing of the wires against other components.
Attention is directed to the following U.S. Pat. Nos.

SUMMARY OF THE INVENTION
The invention provides an outboard motor comprising a propulsion unit including a power head including an internal combustion engine, a lower unit including a drive shaft housing fixed to the engine, and a propeller shaft journalled by the lower unit and having thereon a propeller, an outer cowling defining an enclosure containing the engine, and an electrical connection assembly mounted on the engine and within the engine enclosure and including at least two of a group of components including a fuse, a relay, a starter solenoid, a suppressor assembly, and an electrical plug-in connection adapted to be connected to a battery cable, and means connected to the propulsion unit and adapted to be mounted on a boat transom for permitting steering movement of the propulsion unit about a generally vertical axis relative to the boat and tilting movement of the propulsion unit about a generally horizontal axis relative to the boat.
The invention also provides an outboard motor comprising a propulsion unit including a power head including an internal combustion engine, a lower u nit including a drive shaft housing fixed to the engine, and a propeller shaft journalled by the lower unit and having thereon a propeller, an outer cowling extending to the drive shaft housing and defining an enclosure containing the engine, an electrical connection assembly mounted on the upper starboard side of the engine and within the engine enclosure and including a fuse, a relay, a starter solenoid, and an electrical plug-in connection, and an electrical power line entering through the opening into the engine enclosure and extending to the plug-in connection, and means connected to the propulsion unit and adapted to be mounted on a boat transom for permitting steering movement of the propulsion unit about a generally vertical axis relative to the boat and tilting movement of the propulsion unit about a generally horizontal axis relative to the boat.
The invention also provides an outboard motor comprising a propulsion unit including a power head including an internal combustion engine, a lower unit including a drive shaft A housing fixed to the engine, and a propeller shaft journalled by the lower unit and having thereon a propeller, an outer cowling extending to the drive shaft housing and defining an enclosure containing the engine, an opening located in the starboard side of one of the cowling and the drive shaft housing and communicating with the engine enclosure, an electrical connection assembly mounted on the upper starboard side of the engine and within the engine enclosure and including a fuse, a relay, a starter solenoid, and plug-in connections for all incoming electrical wiring, a fuel line entering through the opening into the engine enclosure, a shift cable entering through the opening into the engine enclosure, a throttle cable entering through the opening into the engine enclosure, and an electrical power line entering through the opening into the engine enclosure and extending to the electrical connection assembly, and means connected to the propulsion unit and adapted to be mounted on a boat transom for permitting steering movement of the propulsion unit about a generally vertical axis relative to the boat and tilting movement of the propulsion unit about a generally horizontal axis relative to the boat.
Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims and drawings.
