    摘要: An outboard motor having a multi-cylinder four-cycle, internal combustion engine as a power plant. The engine is provided with an oil reservoir in the upper portion of the drive shaft housing and lower unit. Oil is drained back to this oil reservoir by separate drain passages formed in the cylinder head and in the crankcase. In addition, an improved crankcase ventilating system is provided wherein the crankcase ventilating gases follow a circuitous path through the crankcase chamber, camshaft chambers and then to the intake system so as to reduce the emissions of hydrocarbons.

    摘要: An outboard motor cooling system wherein the coolant is circulated through the various cooling jackets so that it first flows into proximity with at least a portion of the exhaust system cooling jacket and then into the cooling jackets of the main engine body that cool the cylinder bore and combustion chamber. Sacrificial anodes are positioned both in the main engine body cooling jacket and in the exhaust system cooling jacket. In addition, a temperature sensor is positioned in a low portion of the cooling jacket and where the water has passed through the exhaust cooling jacket and before it enters the main engine body cooling jacket so as to provide accurate temperature indication while protecting the temperature sensor from excess temperature conditions particularly after engine shut off.

    摘要: A cowling for an outboard motor of the type having a water propulsion device powered by an internal combustion engine positioned within an engine compartment defined by the cowling, is disclosed. The cowling has at least one intake vent positioned therein and includes an engine cover which defines an isolated intake air path from the vent across a top end of the engine to an engine air intake. The cover also defines a chamber in which a flywheel rotated by the crankshaft at the top end of the engine is positioned. The chamber has an inlet in communication with the engine compartment, and an outlet leading to an exhaust passage. The exhaust passage leads to an exhaust vent in the cowling.

    摘要: In accordance with the present invention there is provided an outboard motor for use in powering a watercraft of the type having an operator station positioned along a starboard side of the watercraft. The motor has a water propulsion device powered by an engine having an exhaust system generally positioned along a right side thereof. A cooling system is provided for cooling the engine and the exhaust system. Preferably, the motor includes a cooling water tell-tale acting as a visual identifier to the operator of the craft that the cooling system for the engine is operating. The tell-tale is created by diverting coolant from a portion of the cooling system for cooling the exhaust system to a pilot port in the side of the cowling corresponding to the starboard side of the watercraft. In addition, the motor preferably includes a throttle control and shift control which extend along the right side of the engine through the cowling to the operator station in the watercraft. The throttle control is connected via a linkage extending to the opposite side of the engine to an intake throttle, while the shift control is connected via a linkage to a transmission control.

    摘要: An outboard motor for a watercraft includes a simply structured fuel supply system of a smaller size and a longer life than prior fuel supply systems. The fuel supply system includes a delivery fuel tank carried by the outboard motor. Fuel is pumped from an external fuel supply tank carried by the watercraft to the delivery fuel tank by a low-pressure fuel pump located within the outboard motor. A control system controls the low-pressure fuel pump so that a predetermined level of fuel is maintained in the delivery fuel tank. The control system includes a fluid level detection sensor that detects the level of fuel within the delivery fuel tank and produces a corresponding signal indicative of the fuel level. A control unit circuit receives the fluid level signal and determines if the fluid level in the tank is higher or lower than a predetermined maximum fuel level. If the fluid level is determined to be higher than a maximum fuel level, the control unit circuit deactivates the low-pressure fuel pump. If the fluid level is determined to be lower than the maximum fuel level, the control unit circuit activates the low-pressure fuel pump.
