Abstract: A marine drive is for propelling a marine vessel in a body of water. The marine drive comprises a motor housing defining a motor cavity; a motor disposed in the motor cavity; a propulsor shaft extending from the motor housing, wherein the motor is configured to cause rotation of the propulsor shaft; a propulsor which is rotated by the propulsor shaft to create a thrust force in the body of water; and a vent conduit having a first end connected to the motor cavity and a second end which vents the motor cavity to atmosphere.

Abstract: A stowable propulsion system for a marine vessel. A base is configured to be coupled to the marine vessel. A propulsion device is configured to propel the marine vessel in water. A shaft extends along a length axis and pivotably couples the propulsion device to the base. The propulsion device is pivotable into and between a stowed position and a deployed position, wherein pivoting the propulsion device causes the shaft to rotate about the length axis.

Abstract: A stowable propulsion device for a marine vessel. A base is configured to be coupled to the marine vessel. A propulsor is configured to propel the marine vessel in water. An arm pivotably couples the propulsor to the base such that the propulsor is movable into and between a stowed position and a deployed position, where the propulsor is closer to the base in the stowed position than in the deployed position. A first actuator pivots the arm so as to move the propulsor into and between the stowed position and the deployed position. A second actuator is manually actuatable to pivot the arm so as to move the propulsor towards the stowed position.

Abstract: A stowable propulsion device for a marine vessel having a deck. A base is configured to be coupled to the marine vessel below the deck. A propulsor is configured to propel the marine vessel in water. An arm couples the propulsor to the base such that moving the arm moves the propulsor into and between a stowed position located proximate to the marine vessel and a deployed position located relatively distal from the marine vessel as compared to the stowed position, and such that moving the arm rotates the propulsor about the arm. An actuator comprises a first link movably coupled to the base and a second link that movably couples the first link to the arm. An actuator moves the actuator linkage to thereby move the propulsor into and between the stowed position and the deployed position.

Abstract: A battery box includes a housing defining an interior of the battery box, a ledge projecting into the interior of the battery box, and a box electrical connector installed on the ledge. The interior of the battery box is configured to receive a battery therein. The battery has a projecting portion sized and shaped to abut the ledge when the battery is installed in the battery box. A battery electrical connector on the projecting portion of the battery mates with the box electrical connector upon installation of the battery in the battery box.

Abstract: A stowable propulsion system for a marine vessel. A base is configured to be coupled to the marine vessel. A shaft has a proximal end and a distal end with a length axis defined therebetween, where the shaft is pivotably coupled to the base and pivotable about a transverse axis between a stowed position and a deployed position, and where the distal end is closer to the marine vessel when in the stowed position than in the deployed position. A gearset is engaged between the shaft and the base, where the gearset rotates the shaft about the length axis when the shaft is pivoted between the stowed position and the deployed position. A propulsion device is coupled to the distal end of the shaft. The propulsion device is configured to propel the marine vessel in water when the shaft is in the deployed position.

Abstract: A marine propulsion device has an internal combustion engine, an exhaust manifold that conveys exhaust gas from the internal combustion engine, and a cooling water sprayer that is configured to spray a flow of cooling water radially outwardly toward an inner diameter of the exhaust manifold. The cooling water sprayer has a sprayer body that is configured to convey the flow of cooling water radially into the exhaust manifold and a nozzle configured to spray the flow of cooling water radially outwardly in a fan-shaped pattern toward the inner diameter of the exhaust manifold.

Abstract: A valve actuating system determines a shape of its jam nut surface as a function of a resultant force on a ball stud exerted by a rocker arm on the ball stud during operation of the valve train. The contact surface of the jam nut, which is pressed against an associated surface of the head of an engine, is a conical surface with an included angle that is generally twice the magnitude of an angle between a resultant force on the ball stud and a central axis of the ball stud and its associated jam nut. Certain accommodations can be made in order to reduce the cost of the system that would occur if perfect mathematical preciseness with a most preferred embodiment of the present invention is employed.
