Inhibiting
WARNING! Observe the following rules when
cleaning with high-pressure water jets. Never
direct the water jet at seals, rubber hoses or
electrical components. Never use a high pres-
sure jet when washing the engine. Vent the fuel system according to the instructions
on page 54. Start the engine and run on fast idle
until approx. 2 liters (0.5 US gals) have been used
from the can.
Stop the engine and drain or pump the lubricating
oil from the oil sump. Connect the regular fuel
lines.
6. Check that the coolant in the freshwater system
has sufficient antifreeze and top up if required. Or
drain the coolant. Close the sea cock and drain
the water from the seawater system. See pages
32–33.
Remove the seawater pump impeller.
7. Check that the batteries are kept well charged. A
discharged battery may easily burst.
Batteries always have a certain amount of self-
discharge which increases the higher the tempera-
ture. Batteries in storage should therefore be kept
as cool as possible. They should be stored dry
and clean and normally charged when the electro-
lyte density drops below 1.24 g/cm
3 (1.20 g/cm 3
for batteries with tropical acid).
You should preferably remove the batteries and
hand them in for maintenance charging as in-
structed by the manufacturer.
See also point 2 under the heading “Electrical
System – Important” on page 70.
8. When necessary, improve the external rust
protection by brushing on anti-corrosion oil. The
surfaces should be clean and dry before being
treated.
NOTE! Certain engine conservation oils are
inflammable. Some of them are also dangerous if
inhaled. Ensure that ventilation in the work place
is good. Use a protective mask when spraying.
9. Stick a label on the engine stating the date of
inhibition, type of inhibition and the inhibiting oil
used.
10. Cover the engine’s air intake, exhaust port and
the engine itself if so required.
Launching procedures
Check the condition of the propeller(s). Damaged
propellers should be reconditioned or replaced.
Boat unused for up to two months
If the boat is not expected to be used for up to two
months, it is sufficient to start the engine and warm it
up once a fortnight.
If there is a danger of freezing, the cooling system’s
seawater circuit should be drained after stopping.
Check/top up the freshwater system’s antifreeze to
prevent damage. Drain the freshwater tank if installed.
Remove the drain plug (if fitted) on the exhaust pipe
condensed water collector. Drain the water from any
low-lying parts on the exhaust pipe.
Check the batteries’ charge condition. A discharged
battery may easily burst.
Boat unused for more than two months
1. Warm the engine up to normal operating tempera-
ture.
2. Check that the lubricating oil level in the reverse
gear reaches the upper mark (“FULL”) on the
dipstick. Check the level with the engine idling
and the control in neutral.
3. Stop the engine and drain or pump the lubricating
oil from the oil sump.
4. Boat unused for up to max. 8 months: Replace
the lubricating oil filter and fill with Volvo Penta
lubricating oil to the normal level. Warm the
engine up after changing the oil.
5. Boat unused for more than 8 months: Fill the
engine with inhibiting oil to just above the lower
part of the mark on the dipstick. The oil compa-
nies sell inhibiting oil.
Connect the fuel lines (suction and return) to a
can filled with 1/3 inhibiting oil and 2/3 diesel.
Some oil companies sell a ready-mixed oil for this
purpose.
