ABSTRACT:
A trolling valve safety device that locks or limits actuation of a boat engine throttle from its idle position during use of a trolling valve, and vice versa, preferably includes a rotating control plate having mounts for throttle cables so that throttle actuation requires plate rotation. This rotation can be limited by a cam slider which slides under force of trolling valve control cables and provides a cam member that inserts in control slots of the control plate. The cam member is positioned in a locking radial slot when the trolling valve is engaged and thereby locks or limits engine throttling. The cam member is positioned in a releasing arcuate position when the trolling valve is disengaged and thereby permits rotation of the plate and associated engine throttling. A stop pin can also extend from the plate to selectively permit or limit rotation of the plate by alignment or disalignment with a groove in the cam slider and can be adjustable to permit slight throttling during trolling valve use. A series of switches can also be provided to coordinate various engine safety devices and controls with the condition of the trolling valve and the throttle of the engine.
