摘要： A marine engine comprises a powerhead having an engine block, a cylinder head and a crankcase containing a crankshaft. Operation of the marine engine causes rotation of the crankshaft. A crankcase cover encloses the crankshaft in the crankcase. A supercharger is on the crankcase cover, the supercharger being configured to provide charge air for combustion in the powerhead. The supercharger comprises a charge air outlet for conveying charge air from the supercharger for combustion in the powerhead, the charge air outlet being oriented so as to discharge the charge air towards the powerhead.

摘要： A trim control system for controlling a relative position of a trimmable marine device with respect to a marine vessel hull includes a trim actuator coupled to the trimmable marine device about a horizontal trim axis. The trim control system further includes a trim control module executable on a processor and configured to identify a target trim position for the trimmable marine device, determine a desired trim rate of change to rotate the trimmable marine device about the horizontal axis from a current trim position toward a target trim position, and operate the trim actuator to rotate the trimmable marine device at the desired trim rate of change toward the target trim position.

摘要： A method of controlling two or more propulsion devices on a marine vessel includes receiving a vessel speed, determining that the vessel speed is below a first vessel speed threshold, receiving an operator thrust demand, and determining that the operator thrust demand is below a first demand threshold. At least one of the two or more propulsion devices is then turned off, and a thrust output of at least one remaining propulsion device is adjusted based on the operator thrust demand.

摘要： A cooling system is for cooling a marine engine having an engine block and a cylinder head, and a supercharger configured to provide charge air for combustion in the marine engine. The cooling system has a charge air cooler configured to cool the charge air prior to combustion in the marine engine. The cooling system is configured to circulate cooling water from a body of water in which the marine engine is operating to the marine engine and then back to the body of water. The cooling system is further configured to convey the cooling water in parallel to the marine engine and the charge air cooler. A sprayer is configured to spray the cooling water into exhaust gas discharged from the marine engine. The cooling system is configured to convey the cooling water in series to the charge air cooler and then to the sprayer.

摘要： A marine propulsion device includes an internal combustion engine driving a driveshaft into rotation and a starter-generator motor in a torque transmitting relationship with the driveshaft. The starter-generator motor is alternately operable in a positive torque mode where it is powered by a battery to exert a positive torque on the driveshaft, and in a negative torque mode where it exerts a negative torque on the driveshaft and generates a charge to the battery. A control module is configured to receive an engine RPM, determine an engine RPM drop rate, and determine that the engine RPM drop rate exceeds a threshold drop rate. The starter-generator motor is then operated in a positive torque mode based on the engine RPM drop rate when the engine RPM drop rate exceeds the threshold drop rate.

摘要： A lash adjustment device is for a valve train in a marine engine. The lash adjustment device comprises an external hollow body and a ball shaft that is telescopically movable in the hollow body. The ball shaft has a through-bore for receiving oil and having an annular lower end surface and an upper end surface. Oil flow into the hollow body pushes on the lower end surface and forces the ball shaft to telescope outwardly with respect to the hollow body. An absence of oil flow in the hollow body allows the ball shaft to telescope inwardly with respect to the hollow body until the annular lower end surface engages with an internal stop surface formed in the hollow body.
