47
PROPER ATTENTION TO AND MAINTENANCE OF
YOUR ENGINE WILL ASSURE YOU MANY HOURS
OF PLEASURABLE, SAFE BOATING, AND WILL
PREVENT UNNECESSARY ENGINE PROBLEMS.
YOU MUST, THEREFORE, BECOME
THOROUGHLY FAMILIAR WITH ALL ASPECTS OF
THE ENGINES PROPER OPERATION OUTLINED
IN THE MANUFACTURERS OPERATOR’S
MANUALS.
OPERATIONAL HAZARD
Take proper care when washing down or
cleaning your engine to ensure water does
not enter the air in-takes. Water in the air
intakes may travel directly to the cylinders,
resulting in rust and possible internal engine
damage.
Follow the fuel and lubrication requirements in the
manufacturer’s engine manual. Check oil levels prior
to starting, and use lubricants as recommended.
Always check fuel lines and connections for possible
leaks, which may create a dangerous situation.
ENGINES ARE NOT WARRANTIED BY THE
HUNTER CORPORATION; ENGINE WARRANTIES
ARE WRITTEN BY THE ENGINE
MANUFACTURERS
.
EXPLOSION/FIRE HAZARD
Fuel system connections that are too loose
or too tight can leak, resulting in possible
fuel loss, environmental pollution, explosion
or fire hazard.
If you use your outboard in salt water, wash down the
exposed drive unit after every use to limit corrosion.
Also, it is recommended to completely flush out the
raw water cooling system as described in the
manufacturer’s owner’s manual. Regularly check the
propeller and drive unit for any damage or other signs
of serious wear. Propeller damage will reduce
performance as well as contribute to other potential
engine problems.
GENERAL INSPECTION RULES
1.
Conduct Periodic Inspections for Your Safety -
The functions of engine components will
degenerate and engine performance will drop
based on engine use. If countermeasures are not
taken, you may encounter unexpected troubles
while cruising at sea. Consumption of fuel or
lubricating oil may become excessive and exhaust
gas and engine noise may increase. These all
shorten the life of the engine. Periodic inspection
and service increase your safety at sea.
2.
Inspect Before Starting - Make it a daily rule to
inspect before starting.
3.
Periodic Inspections at Fixed Intervals -
Periodic inspections must be made after every
manufacturer’s recommended hours of use.
Conduct periodic inspections according to the
procedures described in your outboard engine
manufacturer’s manual. Routine inspection and
maintenance is necessary to prolong outboard
life.
Outboards used in rental, commercial, or
other high hour applications require more
frequent inspections and maintenance. Adjust
schedule for operating and environmental
conditions.
4.
Servicing Tools - Have servicing tools available
onboard to be ready for inspecting and servicing
the engine and other equipment.
5.
Tightening Torque of Bolts & Nuts - Over-
tightening of bolts and nuts causes them to come
off or their threads to be damaged. Insufficient
tightening causes oil leakage from the installation
face or issues due to the loosening of bolts. Bolts
and nuts
must be tightened to the appropriate
torque specs. Critical parts must be tightened with
a torque wrench to the correct tightening torque
and in the right order.
