A marine drive has a powerhead and a cowling enclosing the powerhead. The cowling comprises a first cowl portion and a second cowl portion coupled to the first cowl portion and being movable with respect to the first cowl portion into and between a closed cowl position in which the powerhead is enclosed by the cowling and an open cowl position in which the powerhead is accessible. A recoil starter is for starting the marine drive. The recoil starter extends through the second cowl portion and comprises a pull-start handle coupled to the marine drive via a recoil cable. Manually pulling the pull-start handle out of a recoiled position with respect to the marine drive causes the marine drive to start. The pull-start handle is also movable into an offset position, in which the second cowl portion is freely movable into and out of the open and closed cowl positions.

A marine engine has an intake camshaft, an exhaust camshaft, and a crankshaft. Combustion in the marine engine causes rotation of the crankshaft which in turn causes rotation of the intake camshaft and exhaust camshaft. Rotation of the intake camshaft operates intake valves for controlling inflow of air to the marine engine. Rotation of the exhaust camshaft operates exhaust valves for controlling outflow of exhaust gas from the marine engine. A cam phaser is located at least partially inside at least one of the intake camshaft and the exhaust camshaft and is configured to vary a timing of operation of at least one of the intake valves and exhaust valves.

A marine outboard motor for a marine vessel. The marine outboard motor includes: a housing comprising a chamber and at least one inlet arranged to be submerged, in use, into a body of water in which the marine outboard motor is operated, in order to draw water into the chamber; an engine assembly comprising an internal combustion engine; a drive shaft positioned in the housing, wherein the drive shaft is coupled to the internal combustion engine to drive a propulsion arrangement; a cooling system for cooling the internal combustion engine, the cooling system configured convey drawn water along a coolant flow path through the housing to deliver the drawn water to the internal combustion engine; and a sleeve by which the drive shaft is sealed from drawn water within the housing, the sleeve having first and second ends, wherein at least a part of the drive shaft is encased within the sleeve.

An outboard motor includes a first cooling water passage through which first cooling water including water from outside an outboard motor body passes to cool a first cooling target including at least one of an electrical component other than an engine and fuel in a fuel tank, and a first pump that is an electric pump that pumps the first cooling water from outside of the outboard motor body and flows the first cooling water into the first cooling water passage.

A personal watercraft includes: a watercraft body including a hull and a deck covering an upper portion of the hull; a light emitter supported by the watercraft body; and a protection cover covering the light emitter and permeable to light emitted by the light emitter, wherein the watercraft body includes a flow-regulating structure, and the flow-regulating structure includes: a fluid inlet through which an external fluid enters the watercraft body; and an upper flow-regulating wall and a lower flow-regulating wall that are opposed to each other in an up-down direction, the upper and lower flow-regulating walls being located between the fluid inlet and the protection cover to regulate flow of the fluid entering the watercraft body through the fluid inlet and moving toward the protection cover.

A marine outboard motor having an internal combustion engine is provided. The internal combustion engine includes an engine block having at least one cylinder and a valve train comprising a cam, a valve assembly including a valve spring, a roller finger follower, and a pivot post. The pivot post extends from a fixed body of the engine block and defines a contact surface about which the roller finger follower pivots when deflected by the cam during use. The pivot post is moveable relative to the fixed body in a first longitudinal direction (A) against the action of the valve spring. A removable shim is disposed between the fixed body and a portion (182) of the pivot post to space the pivot post from the fixed body in the first longitudinal direction (A) and thereby reduce an amount of lash between the cam and the roller finger follower. The removable shim is dimensioned to fit at least partly around a shaft portion of the pivot post.

An ignition timing controller includes a storage and a processor configured or programmed to function as an ignition timing control section and a knocking determining section. The storage stores at least one of a first ignition timing map associated with a first fuel or a second ignition timing map associated with a second fuel more likely to cause knocking of an internal combustion engine than the first fuel. The ignition timing control section controls the ignition timing based on the first ignition timing map by executing a timing retardation based on the first ignition timing map when it is determined that knocking of the internal combustion engine has occurred. The ignition timing control section controls the ignition timing of the internal combustion engine based on the second ignition timing map by executing a timing advancement correction based on the second ignition timing map when it is determined that the knocking of the internal combustion engine has not occurred.

An outboard motor includes an engine to rotate a propeller and an engine cover that houses the engine. The engine cover includes two divided covers disposed above the engine and that directly face the engine. The two divided covers include two connections that are connected together and that overlap the engine in a plan view.

This oil case of an outboard motor is provided below an engine and stores lubricating oil of the engine. In this method for manufacturing the oil case, the oil case is manufactured so as to comprise: an oil chamber; an introduction path that guides upward cooling supply water drawn in from outside the outboard motor; a delivery path that guides downward cooling discharge water that has cooled the engine; a main exhaust path that guides exhaust gas of the engine downward; and a sub exhaust path that guides exhaust gas during low-speed rotation of the engine. The oil chamber, the introduction path, the delivery path, the main exhaust path and the sub exhaust path form an integral structure.

An outboard motor is provided with: an engine cover in which a first outside air inlet port, an exhaust port, and second outside air inlet ports are formed; and a lower housing that is disposed below the engine cover. The engine cover is provided with a front guide and a rear guide that guide outside air, introduced respectively from the first outside air inlet port and the second outside air inlet ports into the engine cover, downward in the gravity direction.
