摘要： A vessel propulsion apparatus includes an engine and a propulsion unit to be driven by the engine. The engine includes a cylinder head including a combustion chamber and a pair of intake openings to communicate with the combustion chamber. The engine further includes a pair of intake ports respectively including a pair of downstream portions respectively connected to the pair of intake openings. A distance between the pair of downstream portions decreases toward the pair of intake openings.

摘要： An outboard motor includes an engine, a generator to generate power by driving of the engine, a driving force transmitter to transmit a driving force from the engine, a propeller shaft to rotate by being switched from a neutral state in which a clutch is disconnected from the driving force transmitter of the engine at idle to a non-neutral state in which the clutch is connected to the driving force transmitter, and a controller configured or programmed to perform a control to reduce a rotation speed of the engine by regeneration of the generator based on a user's switching operation on a shift operator to switch the outboard motor from the neutral state to the non-neutral state, and then connect the clutch to the driving force transmitter while rotating the engine.

摘要： A cowling has first and second cowl portions that enclose a powerhead on a marine drive. A latching assembly is for latching the first and second cowl portions together. The latching assembly has a retainer portion fixed to the first cowl portion and a latching portion fixed to the second cowl portion. The latching portion comprises a latch arm and a bell crank, the latch arm and bell crank being rotatable into and between a latched position in which the latch arm is latched to the retainer portion and an unlatched position in which the latch arm is unlatched from the retainer portion. A novel detent mechanism mechanically retains the latch arm and bell crank in the latched position and alternately in the unlatched position. A pair of bolted connections that fix the first and second cowling portions together and are located on opposite sides of the cowling.

摘要： A V8 engine, each bank of which is configured such that four crank pins connected to four piston pins via a connecting rod are positioned at 90° intervals when viewed from one end of a crankshaft. The four crank pins on the bank side are offset by 60° relative to the four crank pins on the bank side when viewed from the one end.

摘要： 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.

摘要： To display a multidimensional code representing unique information of an outboard motor, a display device ensures switchably displaying the multidimensional code representing identical information by a plurality of display patterns where ease of reading is mutually different. A multidimensional code creating unit converts the unique information of the outboard motor into the multidimensional code and creates the multidimensional codes by two patterns. That is, a first multidimensional code creating unit creates a multidimensional code for a display pattern that represents the unique information of the outboard motor by the predetermined count of N (one or plural) multidimensional codes. A second multidimensional code creating unit creates a multidimensional code for a display pattern that represents the unique information of the outboard motor by the multidimensional code by reducing an information volume represented by one multidimensional code and increasing the count of multidimensional codes more than the predetermined count N.

摘要： An engine includes a V-shaped cylinder body, first and second exhaust manifolds inside a V-shaped line, and an exhaust pipe. The exhaust pipe includes a first upstream end portion into which exhaust gases discharged from first cylinders to the first exhaust manifold flow, and a second upstream end portion into which exhaust gases discharged from second cylinders to the second exhaust manifold flow. A spiral wound gasket seals a gap between the first exhaust manifold and the first upstream end portion.

摘要： An assembly is for aligning and stabilizing first and second cowl portions on a marine engine. The assembly comprises an engagement member configured to be fixed to the first cowl portion and a retainer apparatus configured to be fixed to the second cowl portion. The retainer apparatus is configured to receive the engagement member when one of the first cowl portion and second cowl portion is moved towards the other of the first cowl portion and the second cowl portion. The retainer apparatus comprises a retainer body and opposing guide members that are pivotable with respect to the retainer body. As the retainer apparatus receives the engagement member, the engagement member engages and causes the guide members to pivot with respect to the retainer body such that the engagement member becomes sandwiched between the guide members, thus aligning and stabilizing the first and second cowl portions.
