CHECK DAILY:
•
Level cooling liquid
•
Hoses for loose connections or deterioration.
•
Water inlet filter.
AFTER FIRST 50 HOURS:
•
Change oil and replace the oil filter.
Have the engine run until it is on temperature and
stop it. Drain oil by the sump pump into a suitable
retainer and fill up with fresh oil. Start the engine
again and have it run for 5 minutes. Stop the
engine again and pause for a few minutes to let
the oil gather in the crankcase. Check the level
again and add oil when necessary.
•
Check and tighten nuts, bolts, and unions, paying
particular attention to the fuel system.
•
Observe the exhaust at the normal full load. The
exhaust must be free from soot. Do not allow the
engine to run with a dirty exhaust without
investigating the cause as this may result in an
expensive breakdown.
•
Check air vent on a regular basis. When the air
vent it not working properly the engine can fill up
with water by siphoning. Water in the combustion
chamber causes serious damage to the engine.
•
Check and readjust V-belt.
•
Check the electrical connections
EVERY 150 HOURS:
•
Change
oil.
•
Check the battery acid level (not applicable when
Mastervolt batteries are used).
•
Check battery terminals for corrosion
•
Check and readjust V-belt
•
Check impeller raw water pump (durability
depends on the purity of the sea water. In sandy
water and warm water wear will increase).
