NOTE: Dual engines are treated as two singles in the same boat and are not connected together.
NOTE: The lanyard stop switch (PPL and PPL/WHT wires) breaks power to the ECM or ignition
to stop the engine. The switch is normally
closed
until activated. Therefore the PPL and PPL/WHT
wires must be connected together if Lanyard Stop Switch is not used, or if the E Stop Switch is
used.
NOTE: E Stop Switch (BLK and BLK/YEL wires) connects ground to ECM to stop engine. The
switch is normally
open
; the circuit closes when 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
