摘要： An exhaust pipe has an upstream-side exhaust pipe extending downward from an engine to house a catalyst for exhaust gas purification, and a downstream-side exhaust pipe located downstream of the upstream-side exhaust pipe, and extending upward from the catalyst and then bending downward. Under a configuration in which an exhaust pipe is disposed below an engine, with a simple configuration, a catalyst is hardly exposed to water.

摘要： An outboard motor is provided with an upper separator disposed on the lower side of an oil case for storing a lubricating oil of an engine, and an extension case which is separably connected on the lower side of the upper separator. The upper separator has a central exhaust passage through which exhaust gas flows, and a cooling water flow part through which cooling water flows on the outside of the central exhaust passage, the central exhaust passage and the cooling water flow part forming an integrated structure. The exhaust gas and the cooling water are caused to mix in the extension case.

摘要： Exhaust systems are for outboard marine engines that are configured to propel a marine vessel in a body of water. An intermediate exhaust conduit is configured to receive the exhaust gas from the primary exhaust conduit. A primary muffler receives the exhaust gas from a intermediate exhaust conduit. A secondary muffler receives the exhaust gas from the primary muffler. An idle relief outlet discharges the exhaust gas from the secondary muffler to atmosphere. A bypass valve is positionable into an open position wherein the exhaust gas is permitted to bypass the secondary muffler and flow from the primary muffler to the idle relief outlet and into a closed position wherein the exhaust gas is not permitted to bypass the secondary muffler and instead flows from the primary muffler to the idle relief outlet via the secondary muffler.

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： THIS invention relates to a propeller and more particularly, but not exclusively, to a propeller for use with inboard and outboard boat engines. The propeller includes a hollow hub and a plurality of primary blades extending substantially radially outwardly from the hub, with each primary blade including a blade face, a blade back and a root section. The propeller is characterized in that a set of secondary blades are provided inside the hub, and that an inner volume of the hub is in flow communication with a volume radially outwardly of the propeller hub.

摘要： An elongated exhaust conduit comprises a first end receiving hot exhaust gas from a marine engine and a second end discharging the exhaust gas. An elongated cooling water jacket extends adjacent to the exhaust conduit. The cooling water jacket conveys the raw cooling water adjacent to the exhaust conduit to thereby cool the exhaust conduit and warm the raw cooling water therein and discharges the warmed cooling water to cool the marine engine. The cooling water jacket comprises first and second channels that are separate from each other. The cooling water is oriented in a helical flow around the exhaust conduit.

摘要： An outboard motor includes a drive shaft extending vertically from an engine and is rotated by the engine. An upper case covers the drive shaft. A propeller shaft extends perpendicularly or substantially perpendicularly to the drive shaft. A lower case covers the propeller shaft. A front handle is disposed forward of the drive shaft and below an engine cover. A rear handle is disposed rearward of the drive shaft and below the engine cover. The rear handle is disposed in a position lower than a position of the front handle.

摘要： An outboard motor comprises an engine having an exhaust gas discharge opening, a midsection housing coupled below and supporting the engine, and an exhaust pipe having an exhaust inlet in fluid communication with the exhaust gas discharge opening. The exhaust pipe extends downwardly to a primary exhaust outlet. An idle relief port in the exhaust pipe is located in a fluid path between the exhaust inlet and the primary exhaust outlet. A sound-attenuating plenum chamber has an interior that is in fluid communication with an interior of the exhaust pipe by way of the idle relief port. The plenum chamber is a separate component that is exterior to the midsection housing, and exhaust gas flows from the interior of the exhaust pipe to the interior of the plenum chamber without first flowing through the midsection housing.

摘要： Marine engine includes a cylinder block having first and second banks of cylinders that are disposed along a longitudinal axis and extend transversely with respect to each other in a V-shape so as to define a valley therebetween. A catalyst receptacle is disposed at least partially in the valley and contains at least one catalyst that treats exhaust gas from the marine engine. A conduit conveys the exhaust gas from the marine engine to the catalyst receptacle. The conduit receives the exhaust gas from the first and second banks of cylinders and conveys the exhaust gas to the catalyst receptacle. The conduit reverses direction only once with respect to the longitudinal axis.
