摘要： A watercraft has an engine that is controlled to reduce the likelihood of engine damage when the watercraft engine speed is rapidly increased due to a lack of load on the propulsion unit. The engine is controlled by a method that detects engine speed and reduces the power output of the engine by varying degrees depending on the speed of the engine relative to plural predetermine speeds.

摘要： A method and system for defining a program to control the trim position of a propulsion unit mounted on a watercraft for a desired utility mode. Also, a method and system for controlling the trim position in a given utility mode by using the defined program. In defining the program, a first utility mode is defined and the watercraft is operated in the defined mode as in normal operation. Multiple trim positions are selected throughout the course of operation in the defined mode. For each selected trim position, an operational parameter of the watercraft is sensed. Multiple values of the same parameter may be sensed and measured for a single trim position. After the parameters have been sensed for each trim position, a correlated data set is created. A correlated data set is saved to a memory device for each selected trim position of the defined utility mode. In controlling the trim position, the watercraft is again operated in the first utility mode. A current operational parameter is then measured. Having measured the current operational parameter, the correlated data sets are recalled from memory so that the current operational parameter may be compared with the stored parameters in the data sets. The trim position is then selected and set based on the comparison of the current parameter with those stored in the data set.

摘要： The present invention is an ignition control system controlling ignition firing timing of an ignition element associated with an engine having an output shaft powering a water propulsion device, an intake system including a throttle valve, and a sensor providing an output signal corresponding to each revolution of the output shaft. The ignition control system calculates a base ignition firing timing from a time between successive previous output signals, determines if a condition of engine acceleration or deceleration exists from a rate of change in the throttle valve position and modifies the basic ignition firing timing based on a condition of engine acceleration or deceleration.

摘要： A mounting arrangement for a throttle position sensor associated with a throttle valve is disclosed. The throttle valve is positioned within an intake pipe of an intake system of an engine which is positioned in an engine compartment defined by a hull of a watercraft. An output shaft of the engine is arranged to drive a water propulsion device of the watercraft. The intake pipe extends from the engine and is arranged to route air to a combustion chamber of the engine. The throttle position sensor is mounted so as to be shielded by the intake pipe from a source of water within the engine compartment, such as an outlet of an intake duct leading through the hull of the watercraft.

摘要： A small planing watercraft including a hull, a propulsion unit mounted on the hull and a high RPM—high output engine for driving the propulsion unit, wherein the engine includes at least one intake valve and an intake valve timing control system for advancing the opening and closing of the intake valve when the watercraft is operating below a predetermined speed corresponding to a velocity at which the watercraft transitions from non-planing to planing motion. The engine may also include a long air intake passage for low-speed operation and a short air intake passage for high-speed operation, with an air intake control valve in the short air intake passage that is closed when the watercraft is operating below the predetermined speed. The engine may also include an exhaust control valve for constricting the exhaust passage, and a system for at least partially closing the exhaust control valve when the watercraft is operating below the predetermined speed. The invention increases the lower RPM output of a high RPM—high output engine to enable faster transition of the watercraft between non-planing and planing operations. Engine intake air flows over the intake valve timing control to provide a cooling effect.

摘要： An improved shift mechanism for a marine propulsion transmission is provided. The shift mechanism includes a guide that defines a slot that receives a member of a linkage that connects an operator unit with a shift rod. Movement of the shift mechanism is converted into substantially linear motion and a shift position sensor is located at a substantially right angle to that movement. Information from the sensor is transmitted to a control unit and is employed to prevent abrupt starts. The shift position sensor is located on the side of an engine for ease of assembly and maintenance. Movement of the shift mechanism may also cause pivotal movement of the guide and this pivotal movement may be employed to reduce the engine speed and assist shifting.

摘要： An apparatus for reducing vibration on a ship with at least two drive shafts by determining and utilizing an optimum angular offset which corresponds to a minimum vibration level. The apparatus comprises a servo-control circuit for servo-controlling the angular difference between the two shafts to a reference value. A calibration circuit determines the optimum angular offset between the shafts corresponding to the minimum vibration level. A control circuit responds to a control signal by actuating in succession the calibration circuit and then the servo-control circuit, wherein the optimum angular offset is set to the reference value.
