An outboard motor has a top cowl and a service lid on the top cowl is movable into and between a closed position enclosing the powerhead compartment and an open position providing manual access to the powerhead compartment from above the outboard motor. An engine is in the powerhead compartment, wherein a peripheral gap is defined between the top cowl and the engine. A serviceable engine oil device is in the peripheral gap and is manually accessible from above the outboard motor when the service lid is in the open position. A serviceable transmission fluid device is in the peripheral gap and is manually accessible from above the outboard motor when the service lid is in the open position. A serviceable gearcase fluid device is in the peripheral gap and is manually accessible from above the outboard motor when the service lid is in the open position.

A tool for installing and removing a stretch fit belt on a marine engine pulley includes a body having first and second ends, an inner face located adjacent an outer surface of the pulley, and an outer face guiding the belt. A rib on the inner face contacts a pulley groove. A wedge protrudes from a lower portion of the outer face near the body's first end and slopes downwardly from a wedge upper corner to a wedge lower corner located between the body's first and second ends. An overhang protrudes from an upper portion of the outer face near the body's second end and has a curved portion located between the body's first and second ends and a tapered portion extending from the curved portion to the body's second end. The tool is dimensioned to accommodate a width or a thickness of the belt during installation or removal thereof.

A marine engine has a cylinder block with first and second banks of piston-cylinders that are vertically aligned and extend transversely with respect to each other in a V-shape so as to define a valley there between. A crankshaft is caused to rotate by the first and second banks of piston-cylinders. A flywheel is coupled to the upper end of the crankshaft such that rotation of the crankshaft causes rotation of the flywheel. An alternator is located above the cylinder block and coupled to the flywheel such that rotation of the flywheel operates the alternator.

Alternator configurations for outboard motors

An air intake system for an outboard motor provides parallel air flow paths between an opening formed in a cowl of the outboard motor and an air intake manifold of an engine under the cowl. A first air path flows in a relatively direct path between the opening in the cowl and the first inlet of a plenum chamber. A second air flow flows in a less direct path from the opening in the cowl to a second inlet of the plenum chamber. The second air flow is used to remove heat from a preselected component, such as an alternator, before it rejoins the first air flow within the cavity of the plenum chamber and is directed, in combination with the first air flow, through an intake air conduit connected to an outlet of the plenum chamber and to an air intake manifold of the engine.

An isolation mounting system is provided for the purpose of supporting a throttle body structure which is completely supported by an elastomeric support, but is held in non-contact association with an air intake manifold in order to effectively isolate the throttle body structure from vibration. This isolation protects potentially delicate components contained within a component housing that is rigidly attached to the throttle body structure.

An air supply system for a marine engine includes an air duct, or sound attenuator cavity, that receives air through a plurality of inlets and directs air to an outlet of the air duct disposed over a throttle body of an air intake manifold. An air filter assembly is shaped to be attached to a wall of the air duct with a filter medium portion extending into the cavity of the air duct and an outlet port or nipple, extending out of the air duct. A compressor is connected in fluid communication with the outlet port of the air filter assembly through the use of a flexible tube, such as a rubber hose, in order to provide filtered air to the compressor. The air filter assembly is easily removed for inspection and/or replacement and is located with its filter medium within the protective housing of the air duct.
