NOTE: Dual engines are treated as two singles in the same boat and are not connected together.
NOTE: The lanyard stop switch on MerCruiser control (purple and purple/white wires) breaks power to the ECM or ignition to
stop the engine. The switch is normally
closed until activated. Therefore the purple and purple/white wires must be connected
together if lanyard stop switch is not used, or if the E‑stop switch is used.
NOTE: Outboard control E‑stop switch (black and black/yellow wires) connects ground to ECM to stop engine. The switch is
normally open ; the circuit closes when the switch is activated. Wires must be separate unless connected through E‑stop
switch.
Up to 15 amps total accessory power can be provided; on purple wire (switched) and the red wire (continuous power).
An accessory relay kit can be used for loads up to 40 amps. Refer to the MerCruiser Parts and Accessory Guide or
MerCruiser Rigging Guide.
