13.11 Engine
The engine manuals of your yacht cover the maintenance of your engine and should be read
carefully.
IMPORTANT NOTE: Once the engine is started, it may take several minutes in cold water until
it reaches full operating temperature (175°~190°) and should not be put under load to prevent
corrosion.
Before changing the oil, operate the engine until it reaches operating temperature (175 -190 ).
Shut down engine and remove the oil from the crank case by means of a crank case pump
which is supplied.
Frequently check all fuel lines for tightness. Your nose is your best guide; if you smell diesel
fuel, there is probably a leak somewhere in the system. A gentle tightening of each connection
in the fuel lines will often solve the problem.
If you do smell any fumes in the boat, extreme caution must be used to prevent an explosion.
The fresh water cooling system is filled at the plant with a mixture of 50% fresh water and 50%
antifreeze. Special attention of owners is drawn to item 13 on page 13 of the Westerbeke
Technical Manual
13.12 Drive Train
Details of shaft alignment and removal of propeller and stuffing box maintenance are discussed
in Section 7.
13.13 Electrical System Maintenance
Electrical wiring system usually requires little or no maintenance Only exposed terminals and
connections should be checked twice a season and more frequently in a sea air environment for
tightness and any signs of corrosion.
Exposed electric and electronic terminals can be protected with a light coating of vaseline,
silicone resin coat or more recently the teflon grease lubricants available at electronic parts
dealers. Both 12V and 110V sockets and plugs should always be clean and free of moisture. A
smear of light grease on the threads of the sealing caps will assist in making a good seal.
The batteries should be periodically checked with a hydrometer. After this test add distilled
water as needed. The level should be approximately 3/8 inch above the plates. Keep the
vent-plug holes unobstructed and ensure the terminal posts and clamps are kept clean and
tight. Frequent cleaning washes away sea water, acid and dirt that has accumulated and set up
tiny circuits that drain off amperage
Before cleaning a battery, take it to an area that will not bedamaged by acid washed off the
battery. Tighten vent caps and scrub terminals including the top of the battery with a brush
