8LV Series Operation Manual
NOTICE
If you have an installation with two or three engines,
and only one engine is operating, please note that if
the propeller shaft thru-hull (stuffing box) is
lubricated by engine water pressure and the
engines are interconnected, care must be taken
that water from the running engine does not enter
the exhaust of the non-running engine(s). This
water could cause seizure of the non-running
engine(s). Contact your authorized Yanmar Marine
dealer or distributor for a complete explanation of
this condition.
NOTICE
If you have an installation with two or three engines,
and only one engine is operating, the water pickup
(thru-hull) of the non-running engine(s) should be
closed. This will prevent water from being forced
past the seawater pump and eventually finding its
way into the engine. The result of water entering
the engine could cause seizure or other serious
problems.
NOTICE
If you have an installation with two or three engines,
and only one engine is operating, it is important to
limit the amount of throttle applied to the running
engine. If you observe black smoke or movement of
the throttle does not increase engine rpm, you are
overloading the engine that is running. Immediately
throttle back to approximately 2/3 throttle or to a
setting where the engine performs normally. Failure
to do so may cause the running engine to overheat
or cause excess carbon buildup which may shorten
the engine's life.
NOTICE
New Engine Break In: On the initial engine start-up,
check for proper engine oil pressure, diesel fuel
leaks, engine oil leaks, coolant leaks, and for
proper operation of the indicators and/or gauges.
During the first 50 hours of operation operate your
new engine under a substantial load at all times.
For best break-in results operate the engine at
various speeds. Operating the engine in NEUTRAL
must be avoided. During the first 50 hours, avoid
operation below 2000 min
-1
(rpm). During the
break-in period, carefully observe the engine oil
pressure and engine temperature. During the
break-in period, check the engine oil and coolant
levels frequently.
NOTICE
If any indicator illuminates during engine operation,
stop the engine immediately. Determine the cause
and repair the problem before you continue to
operate the engine. Contact your authorized
Yanmar Marine dealer or distributor for service
before operating the engine.
NOTICE
Observe the following environmental operating
conditions to maintain engine performance and
avoid premature engine wear:
• Avoid operating in extremely dusty conditions.
• Avoid operating in the presence of chemical
gases or fumes.
• Never run the engine if the ambient temperature
is above +40 °C (+104 °F) or below -16 °C
(+3 °F).
• If the ambient temperature e40 °C
(+104 °F), the engine may overheat and cause
the engine oil to break down.
• If the ambient temperature is below -16 °C
(+3 °F), rubber components such as gaskets and
seals will harden causing premature engine wear
and damage.
• Contact your authorized Yanmar Marine engine
dealer or distributor if the engine will be operated
outside of this standard temperature range.
NOTICE
Never engage the starter motor while the engine is
running. Damage to the starter motor pinion and/or
ring gear will result.
NOTICE
Any part which is found defective as a result of
inspection, or any part whose measured value does
not satisfy the standard or limit, must be replaced.
NOTICE
Modifications may impair the engine’s safety and
performance characteristics and shorten the
engine’s life. Any alterations to this engine may void
its warranty. Be sure to use Yanmar genuine
replacement parts.
