INSPECTION AND MAINTENANCE
■ Battery
1 Disconnect the battery cords.
2 Clean the exterior of the battery with
fresh water or compressed air. Wipe
off any chemical deposits, dirt and
grease from the battery.
3 A p p l y g r e a s e t o t h e b a t t e r y
terminals.
4 Charge the battery completely
before storing it for the winter.
5 Recharge the battery once a month
to prevent it from discharging and
the electrolyte from deteriorating.
6 Store the battery in a dry place with
its cover attached.
!
● Do not allow the battery to discharge,
since it can be damaged by freezing.
● When storing your outboard for
the winter, open up all the water
drain holes in the gear case to
permit any remaining water to drain
out. If a speedometer is installed,
disconnect the pickup tube and
allow it to drain, then reconnect it
after draining. Trapped water may
crack the gear case or water pump
9
case as a result of expansion when
frozen. Check and replenish the
gear case with case specified Gear
Oil before storing the motor, to
avoid water leakage into the gear
case due to a loose lubricant vent
plug or grease fill plug. Inspect the
gaskets under the lubricant vent
and grease plugs, replace them if
necessary, and reinstall the plugs.
■ Electric Starter Motor
Coat the pinion gears and the shaft of
the electric starter motor with grease.

4. Pre-season check

Have your dealer check the engine
before the season starts, or if your
prefer, be sure to check the following
items yourself:
1 Check the electrolyte level, and
measure the voltage and specific
gravity of the battery.
Specific Terminal
Gravity at 20 °C Voltage (V)
1.120 10.5
1.160 11.1
1.210 11.7
1.250 12.0
1.280 13.2

and the battery cables are properly
installed.

the oil tank to the oil pump.

function properly.
(Be sure to turn the propeller shaft
