摘要： A device and technique for reducing noise experienced by boat passengers from an outboard boat motor is discussed. The device may be implemented in the form of a cover that is adjacent to at least a portion of the boat motor. The cover includes one or more walls or surfaces that reflect or attenuate soundwaves. The cover may be attached to the boat motor and/or the boat. The cover may be integral with the boat motor and/or the boat. The cover may be attached to the boat via a hinge to permit the cover to be pivoted away from the boat motor. The materials used to construct the cover may be provided in layers that help to attenuate, absorb or reflect soundwaves.

摘要： A marine propulsion device is provided. The device includes an engine, a driveshaft that is caused to rotate by the engine, a cowling system, a gearcase that supports a propulsor for imparting a propulsive force in a body of water, and a cooling water circuit that conveys cooling water that exchanges heat with the engine. The cooling water circuit includes an engine dump hose that extends from a first end to a second end. The first end is coupled to a cooling water outlet of the engine. The cooling water circuit further includes an egress component configured to discharge the cooling water from the device along a discharge trajectory parallel to a plane that bisects the device into a port side and a starboard side. The egress component extends through one or more components of the cowling system and is coupled to the second end of the engine dump hose.

摘要： An outboard motor includes a drive source, a drive shaft, a propeller shaft, a first case, a second case, a third case, a bearing, and a bearing housing. The drive shaft extends downward from the drive source. The propeller shaft is connected to the drive shaft and extends in a front-rear direction of the outboard motor. The first case houses the drive source. The second case houses the propeller shaft. The third case is between the first case and the second case in a vertical direction of the outboard motor. The bearing rotatably supports the drive shaft. The bearing is between the first case and the second case in the vertical direction and outside the third case. The bearing housing supports the bearing. The bearing housing is between the first case and the second case in the vertical direction and outside the third case.

摘要： A marine propulsion system for a marine vessel has an outboard motor including a cowl covering an internal combustion engine that powers the outboard motor and an accelerometer mounted to the outboard motor. A control module is communicatively connected to the accelerometer. The control module receives information regarding an acceleration of the outboard motor from the accelerometer. The control module uses the information regarding the acceleration of the outboard motor to do at least one of the following: determine an angle of the outboard motor with respect to gravity; determine an amount of oil in an oil sump of the outboard motor; and determine if a reading of the amount of oil in the oil sump is accurate.

摘要： The invention relates to an arrangement for measuring salinity in water, which arrangement is part of an impressed current cathodic protection system having an electrical circuit comprising a source of electrical power (310); at least one first electrode (315) connected to a positive pole of the power source (310); at least one second electrode (317) connected to a negative pole of the power source (310); a voltage sensor (341); a current sensor (342); and a control unit (313). The control unit is arranged to initiate a measurement sequence at predetermined intervals, wherein the control unit is arranged to connect at least one first electrode (315) to the negative pole of the power source (310) to act as a cathode; connect at least one passive electrode (326) to the positive pole of the power source (310) to act as an active anode; register the output voltage; register the current; determine the circuit resistance using the output voltage and the current; and calculate the resistivity of the electrolyte based on the determined circuit resistance and at least one stored electrode property value, which resistivity is inversely proportional to the salinity. The invention further relates to a vessel provided with such a measuring arrangement and a method for its operation.
