ENGINE MAINTENANCE - 11
WARNING
Hydrogen gases that escape from the battery when
charging are highly explosive. Do not use jumper
cables and a booster battery to start the engine. Do
not recharge a weak battery in the boat. Remove
the battery from the boat and recharge in a well
ventilated area away from fuel vapors, sparks and
open ames.
Follow maintenance instructions and warnings as
supplied by the battery manufacturer. If this information
is not available, follow these guidelines for the proper
battery care.
• Do not operate the engine with an open in the
battery circuit, as this may cause damage to the
alternator. Make sure that all connections are
clean and secure.
• When removing the battery cables, always
remove the negative (-) cable rst, and then
remove the positive (+) cable. When installing
battery cables, install the positive (+) cable rst,
then install the negative (-) cable.
• Periodically check the battery for signs of
corrosion, frayed battery leads or cracked case.
Repair or replace as necessary.
• Periodically check the electrolyte level. Add
distilled water to bring up to the proper levels.
IMPORTANT: Your engine is designed to work with
the standard electronics installed in your boat. If you
add other electrical components or accessories, you
could change the way the fuel injection controls your
engine or the overall electrical system functions. Before
adding electrical equipment, consult your Certied
Dealer. If you don’t, your engine may not perform
properly.
CAUTION
Add-on equipment may adversely aect the
alternator output or overload the electrical system.
Any damage caused as a result will not be covered
by, and may void, your warranty.
FRESH-WATER COOLING SYSTEM
SACRIFICIAL ZINC ANODES
Located in the raw water side of the heat exchanger,
exhaust corners and the VDrive transmission are zinc
anodes which are marked by a decal. To check, remove
the plug and visually check the condition of the zinc rod.
The length of the zinc rod when new is approximately
1.5 inches. If more than one half of the zinc is gone,
replace with a new zinc anode.
Dierent geographic locations and water make-up can
result in either high or low sacricial requirements. A
high rate of zinc anode consumption should also alert
the owner to a possibility of an improperly wired boat
accessory, which would require complete checking by
qualied service personnel.
