Electrical System

The engine's electrical system features cranking,
charging, ignition, and trim/tilt circuits. A battery and
all necessary wiring provide power.
CAUTION! If electrical connections are re-
versed, or wires are disconnected when the
key switch is ON or the engine is running,
sensitive electrical components may be im-
mediately damaged. Do not turn off the main
battery switch until the engine has stopped.

Battery Cables

The following are the minimum specifications for
multi-strand copper cables from the motor to the
battery for all models. The maximum length is 20 feet
regardless of cable diameter.
•
0 to 10 ft. (3.05 m) require a 1/0 AWG (80 MWG)
cable.
•
10 to 15 ft. (3.05 to 4.6 m) require a 2/0 AWG
(100 MWG) cable.
•
15 to 20 ft. (4.6 to 6.1 m) require a 3/0 AWG
(120 MWG) cable.
CAUTION! Do not use aluminum core battery
cables. Failure to use battery cables of rec-
ommended gauge and material could result
in poor starting and electrical component
damage.

Batteries and Connections

NOTE! Whenever you replace your battery, read
and understand the information supplied
with it before you begin installation.
Battery Requirements:
All EFI engines ................... 650 CCA non-deep cycle

12-volt, heavy duty marine battery, with adequate
amperage for the engine model installed on your
