A method of controlling a marine propulsion system is provided wherein the marine propulsion system includes at least one rear marine drive steerable to a range of steering positions. The method includes receiving a propulsion demand input. For each of the at least one rear marine drive, a propeller direction and a commanded steering position are determined based on the propulsion demand input, a steering actuator is controlled to steer the rear marine drive toward the commanded steering position, a delayed time to begin propeller engagement is determined to coordinate initiation of propeller rotation with the rear marine drive reaching the commanded steering position. The rear marine drive is then controlled to begin rotating the propeller in the propeller direction based on the delayed time to generate the surge movement, the sway movement, and/or the yaw movement commanded.

Marine propulsion system and control method

A marine propulsion system for a marine vessel includes one steerable rear marine drive positioned along the center line of the marine vessel and a lateral marine drive positioned at a bow region of the marine vessel. The rear marine drive is steerable about a vertical steering axis to a range of steering angles. The lateral marine drive is positioned at a fixed angle with respect to the marine vessel and configured to generate lateral thrust on the marine vessel. A user input device is operable by a user to provide a propulsion demand input commanding surge movement, sway movement, and yaw movement of the marine vessel, and the control system is configured to control steering and thrust of the rear marine drive and thrust of the lateral marine drive based on the propulsion demand input to generate the surge movement, sway movement, and/or the yaw movement commanded by the user.

Marine propulsion system and method with single rear drive and lateral marine drive

A method for controlling a marine propulsion device to have sufficient power available within a power system to meet demands, the marine propulsion device having an engine rotatably engaged with a transmission via a clutch. The method includes measuring the power available within the power system and measuring the demand for power on the power system. The method further includes determining a power difference between the demand and the power available within the power system, and comparing the power difference to a minimum threshold. The method further includes increasing a speed of the engine and increasing a slip of the clutch when the power difference is exceeds the minimum threshold.

Systems and methods for controlling power generation and transmission output speed for marine propulsion devices

A method for controlling a marine propulsion device having an engine rotatably engaged with a transmission via a clutch, and rotatably engaged with a charging device for charging a battery. The method includes measuring a voltage of the battery and comparing the voltage to a minimum threshold. The method further includes increasing a speed of the engine when the voltage is below the minimum threshold, and also increasing a slip of the clutch when the speed of the engine is increased in response to the voltage being below the minimum threshold.

A marine propulsion system for a marine vessel has a first marine propulsion device coupled to the marine vessel and a second marine propulsion device coupled to the marine vessel. The first marine propulsion device has a first engine controlled by a first electronic control module. The second marine propulsion device has a second engine controlled by a second electronic control module. In response to the first marine propulsion device being keyed ON, the second electronic control module of the second marine propulsion device is turned ON.

Marine propulsion system and method for preventing collision of marine propulsion devices

A marine engine has a crankshaft that rotates about a crankshaft axis; a crankcase supporting the crankshaft, the crankcase being made primarily of a first material; and a cover on the crankcase. The cover includes a heat exchanger having an inner plate facing an interior of the crankcase, and the inner plate is located such that rotation of the crankshaft causes lubricant in the crankcase to impinge upon the inner plate. The cover also includes a frame holding the heat exchanger and isolating the heat exchanger from direct contact with the crankcase. At least a portion of the frame is made of a second material that is more compliant than the first material.

A marine propulsion system for a marine vessel includes a first marine propulsion device rotatable with respect to the marine vessel about at least one of a first steering axis and a first tilt-trim axis and a second marine propulsion device rotatable with respect to the marine vessel about at least one of a second steering axis and a second tilt-trim axis. A first control module controls operation of the first marine propulsion device, and a second control module controls operation of the second marine propulsion device. In response to one of the first and second marine propulsion devices being commanded to rotate about at least one of its respective first or second steering axis and its respective first or second tilt-trim axis, the respective first or second control module of the other of the first and second marine propulsion devices is turned ON.

A transmission for an outboard motor, the transmission having an input shaft with an input gear. A countershaft has a countershaft driven gear and a reverse driving gear, where the countershaft driven gear meshes with the input gear. An output shaft has first and second driven gears. First and second driving gears mesh with the first and second driven gears. A reverse idler gear meshes with the reverse driving gear and also with a reverse driven gear. A plurality of clutches includes first, second, third, and reverse clutches. The first and second clutches selectively rotate the first and second driving gears with the countershaft in first and second modes in forward rotation, respectively. The third clutch selectively rotates the second driving gear with the input shaft in a third mode in forward rotation. The reverse clutch selectively rotates the output shaft with the reverse driven gear in reverse rotation.

Multi-speed transmissions for marine propulsion devices

An electromechanical lockout device for a remote control on a marine vessel includes an electric actuator and a locking pin having an engagement end and a second end. The locking pin is arranged with respect to a control lever such that the locking pin is positionable in a locked position, where the engagement end of the locking pin prevents rotation of the control lever into a reverse position, and in a retracted position, where the engagement end of the locking pin allows rotation of the control lever into the reverse position. A method of controlling lockout for a remote control includes sensing a position of a control lever, calculating a rate of change of the position, and engaging a lockout to prevent a gear system from shifting into reverse gear if the rate of change exceeds a threshold rate of change.

Lockout for remote controls on marine vessels

An outboard marine engine comprises a vertically aligned bank of piston-cylinders; an intake camshaft that operates a plurality of intake valves for controlling inflow of air to the bank of piston-cylinders; an exhaust camshaft that operates a plurality of exhaust valves for controlling outflow of exhaust as from the bank of piston-cylinders; and a cam-to-cam connector that connects the intake camshaft to the exhaust camshaft such that rotation of one of the intake and exhaust camshafts causes rotation of the other of the intake and exhaust camshafts. The cam-to-cam connector is located vertically above a lowermost intake valve in the plurality of intake valves, vertically above a lowermost exhaust valve in the plurality of exhaust valves, vertically below an uppermost intake valve in the plurality of intake valves and vertically below an uppermost exhaust valve in the plurality of exhaust valves.

Arrangements for outboard marine engines having reduced width

An outboard marine engine comprises a vertically aligned bank of piston-cylinders; a camshaft that operates a plurality of valves for controlling flow of air with respect to the vertically aligned bank of piston-cylinders, the camshaft vertically extending between a lower camshaft end and an upper camshaft end; and a cam lobe at the upper camshaft end. Rotation of the camshaft causes the cam lobe to cam open an uppermost valve in the plurality of valves. A lubricant circuit extends through the camshaft and has a lubricant outlet located at the upper camshaft end. The lubricant outlet is configured to disperse lubricant onto the uppermost valve, which is located above an uppermost cam bearing bulkhead for the upper camshaft end.

Arrangements for lubricating outboard marine engines

An outboard motor has an internal combustion engine and a sump with an interior for holding oil for the internal combustion engine. The interior is defined by a top, a bottom, and sidewalls that extend from the top to the bottom. At least a portion of the sidewalls tapers radially inwardly towards the bottom. An oil pickup conduit extends into the interior and is configured to convey oil from the sump to the internal combustion engine. A bumper is disposed on the oil pickup conduit and separates the oil pickup conduit from the sidewall.

Outboard motors and oil pickup devices for outboard motors

An internal combustion engine for an outboard motor comprises a cylinder block having first and second banks of cylinders that extend transversely with respect to each other in a V-shape so as to define a valley there between. An exhaust manifold conveys exhaust gas from the internal combustion engine and is at least partially disposed in the valley. A supporting mechanism supports the exhaust conduit with respect to the internal combustion engine. The supporting mechanism is configured to allow the exhaust conduit to move with respect to the internal combustion engine in 360 degrees in a plane defined by the lateral and transverse axes, and laterally towards and away from the internal combustion engine, thereby facilitating assembly of the exhaust manifold and the internal combustion engine despite positional tolerance differences there between.
