Abstract
A control unit for an engine of the type having a shift means for shifting between forward, neutral, and reverse and a throttle means for controlling engine speeds between idle and high speed includes a housing and a control handle rotatably supported at one end by the housing. Shift and throttle cables extend between the engine and the housing, and respond to rotation of the handle to control the engine shifting and throttle during portions of the period of rotation of the handle. A lock rod extends through the handle and is adapted at one end to alternately engage and disengage with the housing; and when engaged with the housing, prevents rotation of the handle from a position corresponding to neutral and idle throttle. A trigger at the outer end of the handle is connected to axially rotate the lock rod to radially disengage the other end of the lock rod and permit rotation of the handle out of the neutral and idle conditions. The lock rod engages a lock ring which is coupled to the housing by a pair of pins, the housing being provided with a circular set of holes permitting the neutral position of the handle to be rotated with respect to the housing.
