is easy to keep clean.  Several brands of bilge cleaners 
will dissolve dirt and grime, but will not harm the environ-
ment  when  pumped  overboard.    If  you  keep  the  bilge 
clean, it is much easier to identify leaks or other problems 
if they should develop.
Important:    The  Federal  Water  Pollution  Control  Act  prohibits 
the discharge of oil or oily waste into or upon navigable waters 
in the United States.  Violators are subject to a penalty.
14.3.5  Shower Sump
The shower drains into a sump pump which keeps hair, 
soap  scum,  and  bacteria  from  building  up  in  the  bilge 
and developing an odor.  Periodically clean out the pump  
filter to prevent clogging the pump.
14.4  Mechanical Systems and Components
Refer  to  the  manuals  supplied  by  the  boat  component 
manufacturers  for  their  recommended  periodic  mainte-
nance. The manuals may indicate maintenance require-
ment,  in  addition  to,  the  minimum  maintenance  tasks 
listed in the following charts.
Note:    In  case  of  conflicts  between  the  maintenance  informa-
tion in this manual and the manuals supplied by the equipment 
manufacturer, the equipment manuals take precedence.
14.4.1  Engine Oil
See engine operating manual for recommended oils and 
correct procedures for checking and replenishing oil.
Hot coolant under pressure may boil over and cause 
burns or other serious injury when cap is removed.  
Allow engine to cool.  Open pressure cap slowly to 
allow pressure to vent before removing cap. 
14.4.2  Engine Coolant
See engine operating manual for recommended coolants 
and correct procedures for checking and adding coolant.
14.4.3  Engine Exhaust
Visually inspect  the  engine  and  generator  exhaust  sys-
tems (hoses, joints, manifolds, etc.) for leaks.  Make sure 
all  clamps  are  tight.    Check  hoses  and  exhaust  boxes 
for  damage.    Replace  any  damaged  exhaust  system 
component. 
Note:   Any  discoloration  around  a  joint  or  gasket  usually  indi-
cates a leak.
14.4.4  Generator Oil
See  generator  operating  manual  for  recommended  oils 
and  correct  procedures  for  checking  and  replenishing 
oil.
14.4.5  Generator Coolant
Refer to the generator manual for detailed recommenda-
tions about checking and adding coolant.
14.4.6  Transmission Oil
Refer to the transmission manual for detailed recommen-
dations about checking and adding oil.
14.4.7  Fuel Filter
Refer  to  the  engine  manual  for  correct  information 
about  checking  and  replacing  the  fuel  filter  on  gasoline 
engines. 
For diesel engines, check all fuel filters daily to remove all 
sediment and water from the filter.  Inspect the canister 
for possible corrosion or deterioration.  Replace canister 
if you observe any corrosion or other deterioration.
Replace  the  filter  element  at  least  once  each  season, 
more  often  if  there  is  contamination  of  the  fuel  system.  
Always  replace  the  bowl  gasket  each  time  the  filter  is 
reassembled.  Check carefully for any signs of leakage.
14.4.8  Fuel Line Connections
Check all fuel line connections for leaks at least once a 
year.  Tighten as necessary.
Important:  Be careful when tightening fittings.  Over-tightening 
can crack the flair fittings and flair nuts.  Use only tube wrench-
es when tightening connections.
14.4.9  Batteries
Avoid spilling battery electrolyte into the engine 
compartment or bilge.  Also, avoid getting saltwater 
on or in the battery.  Either condition can create a
