Top-down serviceable outboard motors

An outboard motor comprising:

• a cowl and a service lid on the cowl, the service lid being movable into a closed position enclosing a powerhead compartment and an open position providing access to the powerhead compartment from above the outboard motor,
• an engine in the powerhead compartment, and
• an air intake plenum that is accessible from above the outboard motor when the service lid is in the open position, the air intake plenum being press-fit coupled to the engine such that the air intake plenum is manually removable from the powerhead compartment by lifting the air intake plenum from above the outboard motor,
• the air intake plenum being mounted to the engine via a tool-less press-fit coupling, the air intake plenum also being fixedly coupled to the engine via a fastener requiring a tool to unfasten, the fastener being manually accessible from above the outboard motor.

• an air intake plenum that is accessible from above the outboard motor when the service lid is in the open position, the air intake plenum being press-fit coupled to the engine such that the air intake plenum is manually removable from the powerhead compartment by lifting the air intake plenum from above the outboard motor, and
• an alternator and a flywheel for the engine, the air intake plenum being located above the flywheel.

An outboard motor comprising:

• a cowl and a service lid on the cowl, the service lid being movable into a closed position enclosing a powerhead compartment and an open position providing access to the powerhead compartment from above the outboard motor,
• an engine in the powerhead compartment, a peripheral gap being defined between the engine and the cowl, the peripheral gap being wide enough to permit vibration of the engine without impacting the cowl,
• an air intake plenum accessible from above the outboard motor when the service lid is in the open position, the air intake plenum comprising a recessed wall portion providing an enlarged gap portion of the peripheral gap, and
• at least one serviceable device of the outboard motor located in the enlarged gap portion and being accessible from above the outboard motor.
