Maintenance and Care
If the battery has discharged it must be recharged. If the
boat has not been used for some time, charge the battery
and then trickle charge it (see manufacturer’s recommen-
dations). A poorly charged battery will be damaged and
may burst in cold weather.
Caution!
Follow the instructions supplied with the battery
charger carefully. To avoid electrolytic corrosion
when an external charger is connected, always
disconnect the battery leads before connecting
the charger. When charging, unscrew filler plugs
but leave them in their holes. Be sure there is
adequate ventilation if the batteries are being
charged in an enclosed area.
WARNING!
Always switch off the charging circuit before
removing the battery charger connectors. Never
mix up battery positive and negative terminals.
This may cause sparks and an explosion. Special
instructions apply when boost charging the
batteries. Follow the battery manufacturers
instructions for boost charging.
Engine Alignment
Engine alignment requires special tools and removal of
the drive unit. This should be done when the drive unit is
removed for lubrication during off-season storage
preparations. Because of the special tools required,
engine alignment must be performed by a Volvo Penta
dealer.
Caution!
Failure to check engine alignment could result in
premature failure of propeller shaft components
and connectors and may damage transmission.
