1. A method for adjusting engine throttle in an electronic shift and throttle system, the method comprising the steps of:
- determining a position of a control lever which allows an operator to manually control throttle functions;
calculating a throttle command based on the position of the control lever and sending the throttle command to an engine controller;
adjusting the throttle command in response to a user input received from an input means and sending an adjusted throttle command to the engine controller;
wherein the position of the control lever remains constant as the throttle command is being adjusted.

Abstract
A method of adjusting engine throttle in an electronic shift and throttle system comprises determining a position of a control lever which allows an operator to manually control throttle functions. A throttle command is calculated based on the position of the control lever. The throttle command is adjusted in response to an input received from an input means. The position of the control lever remains constant as the throttle command is being adjusted.

10. A method for adjusting engine throttle in an electronic shift and throttle system, the method comprising the steps of:
-
determining if all running engines are in forward gear; determining a position of a control lever which allows an operator to manually control throttle functions; calculating a throttle command based on the position of the control lever and a throttle curve, and sending the throttle command to an engine controller of each of the running engines; adjusting the throttle command in response to a user input received from an input means and sending an adjusted throttle command to the engine controller; cancelling the adjusted throttle command when the control lever is moved; wherein the position of the control lever remains constant as the throttle command is being adjusted. - View Dependent Claims (11, 12, 13, 14)

15. An electronic shift and throttle system comprising:
-
a control head including a pivotable control lever for manually controlling throttle functions, the control lever being moveable through a range of positions; an engine including a throttle and a throttle actuator for moving the throttle between an idle position and a wide open throttle position; an engine control unit for providing a throttle command causing the throttle actuator move the throttle based on a position of the control lever; and a user input means for increasing the throttle command without moving the control lever; and a user input means for decreasing the throttle command without moving the control lever. - View Dependent Claims (16, 17, 18, 19)
