Replenishing Battery Fluid
The fluid level should be kept between the upper and low-
er level marks.
To refill use only distilled water. Tap water contains miner-
als which are harmful to a battery.
Battery Connections
Battery terminals and connections should be kept free of
corrosion. If cleaning is necessary, remove the corrosion
with a stiff wire brush. Wash thoroughly with a solution
of baking soda and water (one tablespoon of baking soda
to one cup of water). Rinse well with tap water and dry
off with clean shop cloths. Coat the terminals and termi-
nal bolts with Nyogeltgrease.
Battery Charging
CAUTION:
The battery must be removed from the watercraft for
maintenance and charging. Battery electrolyte may spill
and damage the watercraft.
Always disconnect the black (negative) cable first. Electrolyte or fuel vapors may be present in the engine compart-
ment and a spark could ignite them which could cause personal injury. When re-installing battery connect black (nega-
tive) cable last.
WARNING
Keep the battery away from sparks and open flames during charging because the battery gives off gases which
are explosive. If you smell fuel do not attempt to charge the battery. When using a battery charger connect the
battery to the charger before turning on the charger. This reduces the possibility of sparks at the terminals which
could ignite the battery gases. Do not connect charger cables to the battery unless the charger is unplugged.
1. Remove caps from cells. Add distilled water if necessary to bring electrolyte up to proper level.
2. Connect battery to a charger . Set charging rate at 1.9 amps (maximum) and charge battery for ten hours.
CAUTION:
During charging, if the electrolyte temperature rises above 115°F(45°C) or if battery feels hot when touched, re-
duce the charging rate to lower the temperature and increase the charging time.
3. After battery is charged, check fluid level. If it has dropped add distilled water to bring electrolyte up to proper
level.
4. Check results of charging. The specific gravity of each cell must be 1.270 at room temperature. The voltage
should be 14.5 - 15.5 V during charging; 12.2 - 12.8 V after charging.
