A remote control system for a watercraft having a remotely positioned control device and a plurality of control device for operating the engine speed, transmission control and starter. The means for transmitting the signal from the control device to the controlled devices includes a computer that is programmed for moving the throttle of the engine to neutral when a shift is being made and for limiting the speed of the engine in reverse. In addition, and emergency deceleration device is provided for rapidly closing the throttle and shifting the transmission into the opposite direction for emergency deceleration. An improved starter arrangement is incorporated wherein the transmission is moved to neutral upon initiation of a starting sequence and the started is cranked for only a predetermined time interval to prevent overheating.

Remote control system for marine engine

A remote control device for an outboard motor including a remotely positioned controller device that operates control devices carried by the outboard motor through optical fiber transmitted signals. The optical fibers are detachably connected to the controllers so as to permit removal of the controller. In addition, the controller is detachably supported within the associated watercraft so that it may be conveniently removed.

Several embodiments of coupling devices for marine outboard drives for providing a coupling between an engine output shaft and the outboard drive, drive shaft. Each embodiment employs as the coupling a first portion that provides a relatively resilient driving connection for absorbing low speed torque vibrations and a second more rigid driving connection for providing a more positive power transmission at high speeds and high loads. In some embodiments, the more resilient connection is provided by a spring which may comprise either a torsional spring or a torsional coil spring. In other embodiments, elastomeric elements provide the driving connection.
