Abstract
A remote control manually movable handle for a gear selection and throttle selection device is provided with asymmetry in order to improve the mechanical advantage available to the operator when moving the selection handle from neutral gear position to forward or reverse gear position. The total neutral zone is increased in order to provide this improved mechanical advantage while maintaining the generally similar range of travel of the forward gear zone in comparison to known prior art systems. By changing the relative gear teeth arrangements of the remote control system, this asymmetry and resulting mechanical advantage is achieved. A handle shape is provided that results in a general perpendicularity between the handle and a reference line in order to improve the feel of the handle when used by the operator of the marine vessel.
