Abstract

A method of controlling engine RPM in a marine propulsion device having an engine (3) that effectuates rotation of a propulsor (9) through a gear system (5) that shifts amongst a forward gear position, a reverse gear position, and a neutral position, includes determining that a coolant temperature is below a temperature threshold or that a battery voltage is below a voltage threshold, and then increasing an engine RPM setpoint by a compensation RPM amount while the engines (3) remains in an idle state in order to increase the coolant temperature or the battery voltage. When a shift instruction is detected to transition the gear system (5) from the reverse gear position to the neutral position or from the forward gear position to the neutral position, the engine RPM setpoint is reduced by a shift RPM reduction amount during transition of the gear system, and the engine (3) is controlled according to the engine RPM setpoint.
