摘要： An outboard motor includes an electric motor, a motor control board to control the electric motor and having one end higher than another end, a case between the electric motor and the motor control board and including a cooling chamber, a supply flow path connected to the cooling chamber of the case to supply refrigerant to the cooling chamber, and a discharge flow path connected to the cooling chamber to discharge the refrigerant from the cooling chamber. A discharge port of the discharge flow path is located at the one end of the motor control board, a supply port of the supply flow path is located at the another end of the motor control board, a lower end of the discharge port is higher than a lower end of the supply port, and a first wall surface of the cooling chamber extends along the motor control board.

摘要： A V-type engine, an outboard motor, and a ship capable of restricting exposure of a catalyst to water. Cylinders where pistons operate are arranged in a V-shape, a crankshaft driven by driving of the pistons is disposed vertically, and exhaust pipes communicating with exhaust openings in the respective banks of a cylinder head and a catalyst holder that holds a catalyst in a merge portion where the exhaust pipes are merged in a site located on an upper side of the banks are included.

摘要： An outboard motor cooling induction system. A pickup assembly is attached to a boat's transom proximate the keel. An uptake hose from this pickup assembly carries cooling intake water to one or more inlets on the outboard motor's lower unit. An intake plane is provided on the pickup assembly. This intake plane is preferably positioned so that the intake flow is optimized.

摘要： An outboard motor includes an engine, a supercharger that compresses air to be supplied to an air intake of the engine, and a cooler that cools the air compressed by the supercharger. The compressed air is cooled by spraying water obtained by condensing water vapor produced by combustion in the engine to the cooler.

摘要： A method of controlling engine RPM in a marine propulsion device having an engine that effectuates rotation of a propulsor through a gear system that shifts amongst a forward gear position, a reverse gear position, and a neutral position, includes determining that a coolant temperature is below a temperature threshold or that a battery voltage is below a voltage threshold, and then increasing an engine RPM setpoint by a compensation RPM amount while the engines remains in an idle state in order to increase the coolant temperature or the battery voltage. When a shift instruction is detected to transition the gear system from the reverse gear position to the neutral position or from the forward gear position to the neutral position, the engine RPM setpoint is reduced by a shift RPM reduction amount during transition of the gear system, and the engine is controlled according to the engine RPM setpoint.

摘要： An outboard-motor vibration-isolating cooler system apparatus providing a retrofit substitute for the midsection and the lower unit of a standard outboard motor, having a substitute closed-loop cooling system with an exterior heat exchanger, a substitute oil reservoir, a substitute exhaust system, and a substitute propulsion system with an isolating power-take-off shaft, allowing an existing standard outboard-motor powerhead to be used in conditions not conducive to standard open-loop water cooling, such as shallow-water, muddy-water, obstructed-water, seawater, or corrosive-water conditions.

摘要： An exhaust manifold is for an internal combustion engine on an outboard marine engine that is configured to power a propulsor to provide a thrust in a longitudinal direction. The exhaust manifold comprises an exhaust runner that transversely and longitudinally rearwardly conveys the exhaust gas from the internal combustion engine, an exhaust log that vertically upwardly conveys the exhaust gas from the exhaust runner, and an exhaust elbow that conveys the exhaust gas from the exhaust log vertically upwardly, longitudinally forwardly, and then vertically downwardly.
