Battery Connection
ENGINE CONNECTIONS
IMPORTANT: Engine electrical system is negative (–) ground.
1. Connect engine positive (+) battery cable (usually RED) to positive (+) battery terminal.
2. Connect engine negative (–) battery cable (usually BLACK) to negative (–) battery terminal.
TRIM PUMP CONNECTIONS
In order to install MerCruiser’s Trim Pump in the manner recommended by the American Boat and
Yacht Council (ABYC), some installations will require the use of an accessory Cable Assembly.
In an effort to best support all boat builders, MerCruiser has developed three methods to facilitate
compliance with ABYC recommendations. These come in the form of one standard production
and two accessory kits:
1.
Installations with batteries (or battery banks) rated less than or equal to 800 cold
cranking amps (CCA) and without a battery switch:The trim pump may be installed using
the current standard production assemblies (per instructions) without the purchase of
additional kits or accessories. Either of the kits below may be installed and remain in
compliance with ABYC recommendations.
2.
Installations with batteries (or battery banks) rated more than 800 CCA or with a battery
switch: The red power supply wire (for the Trim Pump) must be connected to the switched
side of the battery switch and either:
a. provided with circuit protection within 7 inches of the point of connection with the power
source or
b. provided with circuit protection within 40 inches of the point of connection with the power
source and sheathed the entire length of wire from the point of connection at the power
source to the circuit protection device.
1. Connect power trim pump BLACK (–) battery cable to negative (–) battery terminal and
appropriate trim pump RED (+) battery cable to positive (+) battery terminal or battery switch.
2. Ensure that all battery terminal connections are tight. Then spray terminals with a battery
connection sealant to help delay corrosion.
1. The propeller torque stated is the minimum torque value.
