A system link adapter can be used to connect SmartCraft link gauges without a System Gauge
(requires resetting tach signal to digital with CDS or DDT) fuel tank and trim gauge setting will be
defaulted. There is no provision with link gauge to calibrate these gauges.

CAN P (CAN 1) CONNECTIONS
CAN P (CAN 1) connection with a terminator resistor in place:
• If a this is a dual engine and the SmartCraft instrumentation is used, the terminator resistor is
removed and a jumper harness connects the CAN P (CAN 1) lines together so that the engines
will share SmartCraft data.
• The resistors on the engines are the required terminator resistors for the SmartCraft‑equipped
dual engine applications.
• If the boat is dual engine and dual helm, the terminator resistor at the lower helm is removed
from the connector. The jumper harness is installed at the upper station.

CAN V (CAN 3) CONNECTION
CAN V (CAN 3) connection is not currently used by MerCruiser. Leave protective cap in place.
GENERAL REPOWER INFORMATION
