A marine control system, the control system comprising:

• a controller;
• one or more connections for one or more control inputs;
• and
• one or more connections for an engine;
• wherein the controller is configured to:
• determine an idle condition of a boat based, at least in part on at least one of the one or more control inputs;
• deactivate the engine based, at least in part, on the idle condition;
• determine a demand for the mechanical output power for the boat based, at least in part, on at least one of the one or more control inputs;
• and
• activate the engine using at least one of the one or more connections for the engine based, at least in part, on the demand.

A method comprising:

• providing, by an engine, mechanical output power for a boat;
• determining an idle condition of the boat;
• disabling the engine based, at least in part, on the idle condition;
• determining a demand for the mechanical output power for the boat;
• and
• enabling, using an auxiliary power source, the engine based, at least in part, on the demand.
