摘要： PURPOSE: To enable a boat of running reversely in the shallows by providing the first and second check valves which change over the tansferred state of working oil between two chambers of a swivel bracket turning cylinder and making the check valves changeable in their motions as that one is opened while the other is closed, or both are closed.
CONSTITUTION: The first chamber 23 and the second chamber 24B inside a cylinder 20 which turns a swivel bracket are capable of being communicated to each other by a bypass passage 32 bypassing a main piston 22. The bypass passage 32 has the first and second check valves 33 and 34 which are arranged reversely to each other in the series relation. At the reverse locking time of a propelling unit which is opened and closed via a cam 36 by the action of a sift lever 35, the unit closes the valve 33 and opens the valve 34. At the tilt-up time of the propelling unit, or at the time of forward run of a boat in the shallows, the unit opens the valve 33 and closes the valve 34. For the forward and rearward run of the propelling unit in the shallows, the unit closes both the valves 33 and 34 to perform their checking functions.

摘要： PURPOSE:To ignite an engine at optimum timing in both starting and warming it by igniting it at prescribed start ignition timing at the time of the starting where a start switch is closed, and changing ignition timing in responce to engine temperature at the time of the engine warming. CONSTITUTION:A start switch for enabling an engine to start, a temperature detector 35 for detecting engine temperature, an ignition timing setting device 30 for setting engine ignition timing, and a crank angle detector for detecting a crank angular position are provided. Further, an ignition signal generator 31 is provided for generating an ignition signal when a crank angle is positioned on the optimum ignition timing based on the detected result of the crank angle detector and the ignition timing setting device 30. At the time of engine starting where the start switch is closed, the engine is ignited in prescribed start ignition timing. At the time of engine warming where engine temperature is less than a prescribed value, it is ignited by the ignition timing setting device 30 at each ignition timing for warming predetermined in responce to the transition of the engine temperature.
摘要翻译：目的：通过在启动开关闭合时的规定的启动点火正时通过点火启动和升温来点燃发动机，并且在启动开始时将点火正时改变为发动机温度发动机变暖。构成：提供一种启动发动机启动的启动开关，用于检测发动机温度的温度检测器35，用于设定发动机点火正时的点火正时设定装置30以及用于检测曲柄角位置的曲柄角检测器。此外，提供点火信号发生器31，用于根据曲柄角检测器和点火正时设定装置30的检测结果，在曲柄角位于最佳点火正时时产生点火信号。在发动机起动时，启动开关关闭，发动机在规定的起动点火正时点火。在发动机温度低于规定值的发动机升温时，由点火正时设定装置30在与发动机温度的转变相对应的加热预定的各点火正时点燃。

摘要： PURPOSE:To effectively prevent engine knocking by keeping, for a prescribed period of time, ignition timing delayed by the knocking, in a method wherein the ignition timing is fed back for control in responce to knocking intensity. CONSTITUTION:A knocking detector 30 for detecting any knocking produced in an engine, a ignition timing setting device 25 for setting engine ignition timing, and a crank angle detector for detecting a crank angle position are provided. Further, an ignition signal generator 26 is provided for generating an ignition signal when the crank angle is positioned to optimun ignition timing based on the detected result of the ignition timing setting device 25 and the crank angle detector. The ignition timing setting device 25 sets stepwise the ignition timing allowing it to be delayed by knocking detection by the knocking detector 30, while keeping each delayed angle setting state of each stage for each prescribed period of time. Hereby, engine knocking is effectively prevented.

摘要： PURPOSE:To surely restrain engine overheat while reducing its speed without any shock by successively forcing plural cylinders excepting a part thereof to misfire in a prescribed time interval when engine temperature is over a prescribed value. CONSTITUTION:An ignition timing setting device (CPU) 25 forces plural cylinders excepting one part thereof among entire cylinders to successively misfire at a prescribed time interval when engine temperature, throttle opening, and the number of revolutions are over prescribed values. This is effected by a fact that an ignition timing setting signal is not transmitted to an ignition signal generator 26. For example, the sixth cylinder, fifth cylinder, third cylinder, and second cylinder are forced to misfire in order at a certain space in time, and an engine operation is continued only by two cylinders of the first and fourth ones. Hereby, when engine temperature is abnormally raised, the number of revolutions is stepwise reduced, preventing any overheat without any shock.
摘要翻译：目的：当发动机温度超过规定值时，在规定的时间间隔内，通过连续地强制多个气缸（其中一部分）不正常地停止发动机，可以在不产生冲击的同时降低发动机的转速来确保发动机过热。构成：当发动机温度，节气门开度和转速超过规定值时，点火正时设定装置（CPU）25迫使整个气缸中的除了其一部分之外的多个气缸以规定的时间间隔连续失火。这是通过点火正时设定信号不发送到点火信号发生器26的事实来实现的。例如，第六气缸，第五气缸，第三气缸和第二气缸被迫在某个时间上依次失火并且发动机操作仅由第一和第四的两个气缸继续。因此，当发动机温度异常升高时，转数逐步降低，防止任何过热而没有任何冲击。
