Chapter Three
Operation, Lubrication, Maintenance
and Tune-up
A diesel engine must have clean air, fuel, and oil. Regu-
lar preventive maintenance and proper lubrication will
pay dividends in longer engine and transmission life, as
well as safer boat operation.
The lubrication and maintenance intervals provided in
Table 1 are those recommended for normal operation. If
the boat is used under continuous heavy duty or other se-
vere operating conditions, including infrequent use, per-
form maintenance and lubrication more frequently.
Keep the engine and accessory units clean and free of
dirt, grime and grease buildup. It is much easier and safer
to perform service on a clean engine. It is also much easier
to pinpoint any leaks.
Tables 1-6 are located at the end of this chapter.
NOTE
Except where specified, F and D series en-
gines are included when a basic model num-
ber is specified. For example,
3GM
is called out in a procedure, the procedure
also applies to 3GMD and
FUEL REQUIREMENTS
The recommended fuel is number 2 (2-D) diesel fuel.
Be sure the fuel is clean and free of water.
NOTE
Poor fuel is one of the leading causes of
rough engine operation orfailure to start.
Dirty fuel or water in the fuel can cause expensive dam-
age to the fuel injection pump and fuel injectors. Refer to
Chapter Seven.
PREOPERATIONAL CHECKS
Before starting the engine for the first time each day,
perform the following checks:
1. Remove the engine compartment cover or hatch and
check for the presence of fuel fumes. If the boat is
equipped with a bilge blower,
turn it on for a few minutes.
If the smell of strong fumes is present, determine the
source and correct the problem before proceeding.
WARNING
Always have a Coast Guard-approved fire
extinguisher close when working around the
engine.
2. Check the engine oil level as described in this chapter.
Add oil if the level is low.
3. Check the electrolyte level in each battery cell as de-
scribed in this chapter. Add distilled water if necessary.
