Engine Maintenance
volts and the idle alternator on the other engine may
now start charging. This could cause a voltage “spike”
in the engine’s electrical system. In these cases, the
ECM could shut off. When the voltage returns to the
required range, the ECM will reset itself. The engine
should begin to run normally. However, this ECM shut
down occurs so rapidly that the engine just appears
to have an ignition miss. In multi-EFI power packages,
each engine must be connected to its own battery. This
provides the required voltage source for the ECM. In
these applications where battery switches are used,
it is important that each switch be positioned to allow
each engine to run off its own individual battery. DO
NOT run engines with the battery switches in “BOTH”
or “ALL” positions. This will allow the other engine’s
battery to be used in case of emergency to start the
engine with the dead battery.
Alternator Belt Tension
1.0/1.4L Engines: Serpentine belt system maintains
tension with a spring-loaded tensioner. Normally, no
maintenance is required.
Closed Cooling System
Surge Tank:
The surge tank replaces the radiator/
keel cooler filler neck and pressure cap and is pressure
capable. Maintain the appropriate level in the surge
tank at all times. If coolant is consistently low,
additional inspection for leaks in the cooling system
may be required.
Filling Closed Cooling System
IMPORTANT!
The closed cooling system must
remain filled year-round with the proper mixture of 50%
antifreeze/50% water to assure protection of
system during the lowest exposed temperatures.
Insure that all drain plugs are installed and tightened.
Fill system with 50/50 antifreeze/water mixture.
After initial fill, start engine and continue filling
surge tank. Engine must be purged of air by bleeding
system. Engines may be bled in a variety of ways;
however, the most efficient method requires a vacuum
fill apperatus.
Battery Cables
Multiple Engine
Battery Precautions - EFI
The alternator is designed to charge the battery that
supplies electrical power to the engine. When batteries
for two separate engines are connected, one alternator
will supply all the charging current for both batteries.
In normal instances, the other engine’s alternator will
not be required to supply any charging current. The
Electronic Control Module (ECM) requires a steady,
stable voltage source. In multiple engine operation,
an electrical onboard device may cause a sudden drain
of voltage at the engine’s battery. The voltage may go
below the ECM’s minimum required voltage of nine (9)

WARNING
CAUTION
Do not recharge a weak battery in a boat. Remove
and recharge in a ventilated area away from fuel
vapors, sparks or fames. Electrical systems in a
marine environment require periodic attention.
Continued use of a weak battery or dirty terminals
can cause solenoid or starter problems. Clean battery
and terminals every 100 hours. Note the condition
of your battery cables. When reconnecting battery
cables make sure that the RED cable is on the (+)
terminal and the BLACK cable is on the (-) terminal.
Black is ground.
Make sure ignition key is removed and engine is not
running before inspecting belts.
DANGER
WARNING
CAUTION
Do not remove pressure cap when engine is hot.
Coolant is under pressure and may be forced out
causing personal injury. After engine is cooled,
remove cap slowly to allow pressure to escape.
