Inhibiting
General
To prevent the engine and other equipment from being harmed during long (2 months or more) periods out of servi-
ce, it must be conserved. It is of utmost importance that the conservation is performed correctly. Therefore we
have compiled a checklist of the most important points. Before taking the engine out of service for long periods, it
should be checked by a Volvo Penta dealer for possible need of overhaul or repair.
WARNING! Read the chapter “Maintenance” thoroughly before starting any maintenance work. It
contains directions for performing maintenance in a safe and correct manner. Certain preservatives are
flammable. Some are also dangerous to inhale. Provide good ventilation. Use a protective mask.
IMPORTANT! The following must be considered when cleaning with a high-pressure water jet: Never
point high-pressure water jets directly at seals, rubber hoses or electrical components. Never use the
high-pressure function when washing the engine.
Preparation
1. Stop up to eight months: Change oil and oil filter
on the engine and then run it warm
Stop over eight months: Treat the lubricating and
fuel systems with conservation oil. See directions
on next page.
2. Make sure there is enough anti-freeze in the coo-
lant. Add more if necessary. An alternative is to
drain the coolant.
3. Drain the rawwater system.
4. Remove the impeller from the rawwater pump.
Keep the impeller in a cool place in a closed plas-
tic bag.
5. Drain off any water and contaminant from the fuel
tank. Fill the tank with fuel to avoid condensation.
6. Disconnect the battery cables and clean and char-
ge the batteries. Trickle charge during the storage
period. A poorly charged battery can freeze and
break.
7. Clean the engine externally. Touch up any paint
damage with Volvo Penta original paint.
8. Spray electric system components with water re-
pellant.
9. Inspect all control cables and apply anti-corrosion
agent.
10. Cover the air intake to the engine, the exhaust
aperture and the engine.
IMPORTANT! Never use vinyl sheets for
covering. This can result in condensation and
harm the installation.
IMPORTANT! Store the engine in a well-
ventilated room.
IMPORTANT! Affix a label on the engine giving
the date, type of conservation and the
preservative that was used.
Care during Storage
Recharge the battery at least once a month.
IMPORTANT! During longer periods out of opera-
tion, the preparations must be repeated every 12
months.
