摘要： A shaft coupling for an outboard motor includes an improved construction that can be held under a good lubricative condition. The outboard motor includes an engine. An engine body defines a first aperture through which a crankshaft extends and is journaled. A recessed portion of the crankshaft defines inner spline grooves. A support member that supports the engine body has a second aperture. A driveshaft extends through the second aperture toward the recessed portion. The driveshaft has a tip portion defining outer spline grooves that are coupled with the inner spline grooves. A first seal member is disposed between an outer surface of the output shaft and an inner surface of the first aperture. A second seal member is disposed between an outer surface of the driveshaft and an inner surface the second aperture. The engine body, the support member, the output shaft, the driveshaft and the first and second seal members together define a lubricant chamber to enclose lubricant.

摘要： An exhaust system for an outboard motor includes an internal combustion engine. An intermediate member supports the engine. A housing unit depends from the intermediate member. An exhaust system guides exhaust gases from the engine. The exhaust system includes a main exhaust passage and an idle exhaust passage. The main exhaust passage discharges the exhaust gases that are produced above idle to the body of water through the housing unit. The idle exhaust passage discharges the exhaust gases that are produced during idle to the atmosphere. The intermediate member defines a portion of the main exhaust passage and a portion of the idle exhaust passage. The intermediate member forms a recessed area in the main exhaust passage portion. The idle exhaust passage communicates with the main exhaust passage portion at the recessed area.

摘要： An outboard motor has an exhaust pipe assembly extending through a driveshaft housing. The exhaust pipe is separated into an upstream exhaust pipe and a downstream exhaust pipe which are formed separately from each other. The upstream exhaust pipe depends into the driveshaft housing and has a lower end connected to a pipe support member. An upper end of the downstream exhaust pipe connects to the pipe support member in a manner to communicate with the upstream exhaust pipe. The downstream pipe depends through an opening in a bottom wall of the driveshaft housing, and a mount at the lower end of the pipe is connected to the driveshaft housing in order to secure the pipe in place. The upper end of the downstream exhaust pipe is fit into the pipe support member without the use of fasteners. In this configuration, the downstream exhaust pipe can be removed independently of the upstream exhaust pipe, and can be drawn downwardly through the opening during removal. This enables the downstream exhaust pipe to be easily and quickly replaced.

摘要： A cooling system for an outboard motor includes an improved construction that can inhibit a housing unit of the outboard motor from absorbing heat that causes discoloring of the unit. The outboard motor includes a power head that has an engine. The housing unit depends from the power head. An exhaust conduit is arranged to discharge exhaust gases from the engine. At least a portion of the exhaust conduit extends through the housing unit. A cooling system is arranged to cool at least the portion of the exhaust conduit by coolant. The cooling system includes an inner coolant pool surrounding the portion of the exhaust conduit and an outer coolant pool surrounding the inner coolant pool. The cooling system supplies the coolant to the inner and outer pools. The coolant supplied to the outer pool is cooler than the coolant supplied to the inner pool.

摘要： When an idle period is started, a voltage of the control signal is changed from a value H to a value L. As a result, the analog amplifiers provided in the signal line driver circuit are switched from the normal state to the low-driving power state. At this time, the data signal lines are set to have a constant potential. A gate voltage is changed from Vgh to Vgl at the same time as when the control signal was changed from the value H to the value L. As a result, the gate of each TFT returns to the OFF state from the ON state. The control signal remains at the value L until the idle period is over. In other words, when the next driving period is started, the voltage of the control signal is changed from the value L to the value H. As a result, the analog amplifiers in the signal line driver circuit are switched back to the normal state from the low-driving power state.

The system can have an exhaust passage that is formed in the casing and through which exhaust gas from the internal combustion engine is inducted from the upper part of the casing toward the lower part, a portion of the exhaust passage between an upstream-side passage and a downstream-side passage being configured as an expansion chamber. Also provided is a cooling water passage extending along the exhaust passage and a drain port that permits water to be discharged into the downstream-side passage after passing through the cooling water passage.

摘要： A casing of an outboard motor can be formed with an upper casing, a lower casing, and an extension casing interposed between the upper casing and the lower casing. Water guiding passages, which can be formed with jacket sections or the like, can extend along both inner side surfaces of the extension casing. The water guiding passages can communicate with a space. Water that leaks from a cooling water pump in the space is allowed to flow through the water guiding passages so as to be used as cooling water. A cooling water inlet of each jacket section can be made at a bottom end of a partition, while the cooling water outlet of each jacket section can be made at a top end of a partition. A bottom of each jacket section can be formed with a bottom closure member.

摘要： An outboard motor includes a housing unit that forms an outer wall exposed outside. An engine is disposed above the housing unit. The engine defines a water jacket. A water transfer system is arranged to introduce water from outside of the housing unit to deliver the water to the water jacket and to discharge the water to a location out of the housing unit. The water transfer system includes first and second water passages defined within the housing unit. The first water passage communicates with the water jacket. The second water passage does not communicate with the water jacket. The water transfer system delivers a portion of the water to the second water passage upstream of the water jacket. The second water passage extends next to the outer wall. The first water passage is spaced apart from the outer wall by the second water passage.

摘要： A retainer (A) aligns and retains ends (E) of branch wires (W1) and wires (W2) to be connected with the branch wires (W1) through the use of a wire retaining portion (U). The wire retaining portion (U) is formed with cavities (42) which have a specified depth and into which the wires (W1, W2) are individually inserted, and contact members (60) for coming into contact with the wires (W1, W2) inserted into the cavities (42). The contact members (60) prevent the wires (W1, W2) from coming out of the cavities (42). The contact members (60) also move away from the wires (W1, W2) when necessary. The ends (E) of the branch wires (W1) and the wires (W2) to be connected with the branch wires (W1) can be aligned and retained during a wire arranging operation. After forming a bundle of wires, the wires (W1, W2) can be released from the retainer (A) with their ends (E) aligned. The aligned ends (E) can be easily processed at one time. The number of the wires (W1, W2) to be retained can be easily confirmed.
