Check Engine Raw Water Strainers
The engine draws raw water (seawater)
through an intake in the
IPS POD DRIVE
under the hull, then through an
ENGINE
RAW WATER STRAINER,
then to a heat exchanger that cools the engine coolant.
The engine coolant then circulates through the engine and returns to the heat
exchanger. To cool the engine, there must be adequate supply and circulation
of both raw water and coolant.
Check raw water strainers at the front of the engines to ensure they are not
obstructed with seaweed or other foreign material. A flashlight helps to check
without removing cover.
If the coolant temperature rises while you are underway, check to see if seawater
is flowing freely through the
RAW WATER STRAINER
.
To remove Plexiglas top, unclip the metal retaining band. (Don’t lose the O-ring.)
Pull out the strainer. If you clean it over the side, hold it tight—it doesn’t float.
Check Coolant Level
When the engine is cool, check coolant level by opening
the cap on top of each engine near the
ENGINE RAW WATER STRAINER
. In a cool
engine, it should be about 1” below the top. Consult the Volvo Penta Operator’s
Manual (VPOM) for the proper coolant .
Don’t remove the coolant cap from a hot engine.
Don’t overfill the reservoir. Without expansion room for the coolant,
the engine could be damaged.
Check Engine Oil Level
The red-handled dipsticks are toward the front of the
engines under the forward cockpit hatches. The dipstick for the starboard
engine is on the port side of its engine and the dipstick for the port engine is on
the starboard side of its engine. Check for both the correct level and for
particulates in the oil.
Check Pod Drive Oil
Get down between engines, move aft and reach behind
the IPS drives to unscrew the red cap with the built-in dipstick. Wipe and reinsert
to check level. If the level is low, the fill cap is on top of the pod.
If the oil is not clear, but milky, contact your Volvo Penta service as it
indicates water in the drives due to damage or faulty seals. Prolonged operation
of the drive in this condition will most likely require replacement of the drive.
