1. A method for controlling a marine engine system, the method comprising:
- receiving an operator demand to change an engine speed of the marine engine system;
detecting a panic shift command based on the operator demand;
determining a minimum speed demand value, wherein the minimum speed demand value is a minimum setpoint for the engine speed;
determining a hold period for the minimum speed demand value; and
setting a speed command to the marine engine system at or above the minimum speed demand value for at least the hold period following detection of the panic shift command.

Abstract
A method for controlling a marine engine system includes receiving an operator demand to change an engine speed of the marine engine system, and then detecting a panic shift command based on the operator demand. A minimum speed demand value and hold period are then determined. A speed command to the marine engine system is set at or above the minimum speed demand value for at the least the hold period following detection of the panic shift command.
