After reinserting, be sure to tighten the cap.
DO NOT OVERFILL the crankcase (above the "full"
mark), as the engine will quickly waste excessive
lubricant. If oil is required often, check under the
engine carefully to be sure there is no oil leak, and
if there is, have it corrected promptly.
CHECK THE COOLANT LEVEL.
The heat
exchanger coolant tanks are located in the engine
room on the ceiling forward of the port engine.
Underway, these expansion tanks will have coolant
in them, and the cap on the heat exchanger on the
engines should NOT be opened if coolant shows in
the expansion tank. In fact, unless the engine
appears to be overheating, or you see evidence in
the engine room of a coolant leak, it's probably best to just leave the coolant alone! If coolant is
needed, determine if there is any sign of a coolant leak under the engine, and if there is, do not
run the engine; if no leak, add coolant from the jug of pre-mixed antifreeze/ corrosion
inhibitor/water supplied on the boat. To add coolant, remove the cap on the coolant tank and
add coolant from the supply on the boat. With the engine "cold", add only to a level about 1" up
from the bottom, no more: The coolant expands when the engine gets warm!
VISUALLY INSPECT THE ROOM
whenever you're in the engine room, asking yourself,
"Does everything look right?". Look at the pads under the engines and transmissions: while
some drips are normal, there shouldn't ever be substantial accumulations of any fluids!
CHECK THE SEA STRAINERS ONCE A WEEK
or immediately if any engine
(generator or main) runs "hot". The main engine strainers are by the forward end of each
engine. The genset strainer is at the aft side of the generator cabinet. To check a strainer,
shine a flashlight through it. While some "fuzziness" from trapped thin growth is normal, you
should see the light clearly on the other side; if obscured, you should clean the strainer. See
page 4.47.
