6LY3 Operation Manual
PRECAUTIONS
The Importance of Periodic
Maintenance
Engine deterioration and wear occurs in
proportion to length of time the engine has
been in service and the conditions the
engine is subject to during operation.
Periodic maintenance prevents
unexpected downtime, reduces the
number of accidents due to poor machine
performance and helps extend the life of
the engine.
CAUTION
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.
