Abstract: A marine propulsion device comprising a lower unit including a rotatably mounted propeller, an internal combustion engine mounted on the lower unit and drivingly connected to the propeller, the engine including an engine block, a crankshaft and flywheel assembly including a crankshaft rotatably supported by the engine block and having an end extending from the engine block, and a flywheel mounted on the end of the crankshaft for rotation therewith, and a voltage generator including a magnet mounted on one of the assembly and the engine block, and a coil mounted on the other of the assembly and the engine block, the coil being radially spaced from the magnet, and an annular power takeoff pulley mounted on the flywheel and surrounding the voltage generator in adjacent relation thereto axially of the crankshaft.

Abstract: An outboard engine has a power unit, an extension case extending vertically and having its upper end coupled to the power unit, and a propeller mounted on the lower end of the extension case and driven by the power unit. The power unit comprises an internal combustion engine having a vertically extending crank shaft and a cylinder having its axis extending horizontally, and a cover assembly covering the internal combustion engine. The axis of the cylinder is inclined to one side with respect to the axis of the propeller when viewed in plan. The outboard engine can be handled with utmost ease since it can be laid down during storage or shipment without being drained of engine oil.

Abstract: A marine propulsion device comprising a propulsion unit adapted to be mounted on the transom of a boat for pivotal movement relative to the transom about a steering axis, the propulsion unit including a rotatably mounted propeller, and an engine drivingly connected to the propeller and including a water jacket, a water pump connected to the water jacket for forcing cooling water through the water jacket to cool the engine, a fluid pump driven by the engine, a conduit communicating between the water jacket and the atmosphere, and a fluid cooler communicating with the conduit to receive cooling water from the water jacket and communicating with the fluid pump for cooling the fluid pumped thereby.

Abstract: A lubricant tank arrangement for an outboard motor wherein the lubricant tank is contained within the protective cowling of the power head but its closure cap is accessible directly through the protective cowling. The closure cap is recessed and a sleeve is slidably supported in the neck and is movable between a retracted position and an extended position so as to facilitate filling. An improved sealing arrangement is also incorporated between the cowling and the filler neck so as to prevent the ingress of foreign materials into the interior or the protective cowling through the opening which affords access to the filler neck.

Abstract: Two embodiments of outboard motors including improved protective cowling arrangements for sealingly enclosing a liquid level tank. In each embodiment, a filler neck of the tank extends through an opening in a plate that is affixed relative to the starter handle and which is sealingly engaged with an opening in the protective cowling.

Abstract: A water-cooled diesel engine suitable for use as a marine outboard engine, which has a cylinder head and a cylinder block formed as an integral unit from aluminum or an aluminum-base light-weight alloy. A cooling water jacket, intake ports and exhaust ports are formed in the cylinder head and the cylinder block.

Abstract: A governor for an internal combustion engine, in which a floating lever rotatably supported by a shaft abuts with its one end against the forward end of the governor spindle, the other end of the floating lever being connected through a link member to a control rod for controlling the fuel injection of the engine, and in which a regulator handle is provided, which is operatively connected to the shaft of a grip of a steering handle.

Abstract: An improved lubricating system for a two-cycle outboard motor having a vertically extending crankshaft. The lubricating system employs a crankshaft driven pump and circulating system that permits pressure lubricating without necessitating elongation of the crankshaft or engine. The engine is enclosed within a cowling and an oil sump is conveniently located within the cowling and is accessible through a cover door of the cowling for replenishment of the oil supply without removal of the cowling.

Abstract: A water cooled, four-cycle internal combustion engine particularly adapted for use in an outboard motor. A supporting plate arrangement is used with the supporting plate extending across the driveshaft housing at its upper end. The engine is supported on the upper side of the supporting plate and an oil pan is supported on the underside of the supporting plate and depends into the driveshaft housing. The construction is such that the engine may be removed from the supporting plate without necessitating removal of the oil pan from the supporting plate so as to facilitate servicing. In addition, an oil drain is provided through the supporting plate at such a location so as to insure against leakage of the lubricant from the oil sump back into the engine regardless of whether the engine is in its normal running condition or its tilted up condition.

Abstract: An intake duct for an outboard engine. A cowling atop the engine forms, with a top cover plate, a recess which opens rearwardly. Intake parts are formed at the right and left sides of this recess, near the upper elevation thereof, in the vicinity of the cover plate. This provides for air flow in such a way as tends to remove, in the recess, water which is entrained in the air stream, before the air flows out of the intake ports to the engine.

Abstract: A cowl for the power head (11) of an outboard motor (10) includes two bottom cowl members (14, 15) attached together by screws which also mount a latch bracket (26) and a hinge member (25). The latch bracket (26) supports a latch mechanism which, with the hinge member (25) serves to hold a top cowl member (13) in place.

Abstract: An attachment by which a hydraulic pump is to be driven by an outboard motor has a coupling by which the pump shaft is or can be connected to the support established by the fly wheel of the motor or the fly wheel and the upper end of the crankshaft with the weight of the attached pump transmitted to the support. The attachment also includes torque opposing and pump stabilizing means by which the pump is or may be attached to the motor laterally of the fly wheel. In one embodiment of the invention, misalignment forces are accommodated solely by the torque opposing means and in another embodiment the coupling is flexible.

Abstract: A drive shaft housing for an outboard power leg adapted for attachment to a boat. Inside the housing there are cavities for a cooling water pump and its drive shaft as well as a cavity for a gear with a drive shaft between the gear and the propeller shaft. The housing is die cast in one single piece in which the drive shaft cavity opens upwards and passes into the downwards opening cavity for the cooling water pump.

Abstract: An outboard motor cowl includes separate starboard and port cowl members which are each individually, removably hinged to the rear of the engine by a pair of spaced hinge units which allow separate attachment and removal of the cowl halves. The forward ends of the cowl members are releasably connected to separate and independent mounts. The uppermost aft hinge unit is visible from the front of the motor. Each hinge unit includes a receptacle secured to a mounting plate and a hinge pin secured to the inside of the cowl member in slightly spaced relation to the aft edge. The receptacle is spaced from a back edge sealing bracket and includes a guide member to receive and guide the cowl member. The top hinge pin is longer than the lowermost pin and serves to pilot the lower pin into the proper position. The hinge receptacle and pin support include interfering members which hold the cowl downward in the normal closed position, and require slight pivotal movement of the cowl to release the hold-down members.
