LAYING-UP AND

LAUNCHING GUIDE

VOLVO PENTA DIESEL

AND GASOLINE ENGINES

TIME WELL INVESTED

This guide covers most of the items to be checked

and seen to on your engine and drive when laying

up and launching. Although it won’t take more than

a couple of hours of your time each year, your

engine will run more reliably and economically and

use less fuel, with less chance of unnecessary

breakdowns. Life at sea will be safer.

You will ﬁnd more detailed information in your engine

instruction book and our do it yourself manuals.

Or consult your authorized Volvo Penta dealer, he will

be pleased to carry out your servicing and mainte

nance, if you do not wish to do it yourself. Certain

complicated jobs are, of course, best left to an

authorized dealer since they call for both specialized

knowledge and special tools.

Always use Genuine Volvo Penta Parts. That way

you can be conﬁdent that the parts you use will be

of the right quality and ﬁt perfectly. And make sure

you have tools on board and that your on board

repair kit is complete.

Remember the environment –

collect any oil, coolant, degreaser,

paint, etc., and dispose of them

in the proper containers.

The time intervals mentioned by us are only general and can vary

between different engine types. The operator's manual will give you

the proper intervals for your particular engine. However, entirely

different intervals apply, if you use the engine for commercial purposes

or in very polluted waters.

You should change the engine oil and oil ﬁlter after

approx. 100 hours of operation, or at least once

per season.

Choose Volvo Penta engine oil which has good

inhibiting qualities and ou will not need to add

an special inhibiting oil for a normal winter la -up.

A new oil ﬁlter will remove soot and metal particles

from the oil and prevent unnecessar engine wear.

Genuine Volvo Penta ﬁlters are tested and speciall

designed to suit each particular engine t pe.

Run the engine warm before changing

the oil. It is easier to do this when the

boat is still in the water (it can also be

done in connection with engine inhibiting).

Switch off the engine and use an oil bilge pump to

pump out all the engine oil through the dipstick hole.

Change the oil ﬁlter and ﬁll up with the right amount

of Volvo Penta engine oil. Also change transmission

oil, please refer to the ”Oil changes – drive/reverse

gear” chapter. Run the engine for a while. Check for

oil leaks.

OIL AND OIL FILTER CHANGES

Check the oil level before starting the

engine.

COOLING SYSTEM

INHIBITING SEA WATER COOLED ENGINES

Regular maintenance and servicing of the cooling

s stem is an effective wa of preventing damage

from overheating. It is also important to inhibit the

cooling s stem for the la -up season in order to

avoid frost damage and corrosion.

 Work on the cooling system is best carried out

on land. Otherwise there is a risk of water getting

into the boat.

The engine and reverse gear cooling

water ducts must be ﬂushed and

drained off. Detach the suction pipe

from the inside of the shield on the Aquamatic drive

or from the reverse gear. Connect a hose to the

suction pipe and insert it in a bucket of fresh water.

Make sure that the bucket is continually replenished

with fresh water. Let the engine idle until it warms

up enough to open the thermostat.

 Never let the water pump run dry.

It is important to let the engine run

for a while, in order to ﬂush away any

sludge and salt that could otherwise

cause rusting. Then switch off the engine. Insert the

free end of the hose into a solution of water and

Volvo Penta coolant. Allow the liquid to circulate for

a while, without the bucket becoming empty. Switch

off the engine and replace the suction pipe.

N.B. Leave the liquid in the system, as it provides

good protection against freezing and corrosion.

Check and clean sea water ﬁlter, if ﬁtted.

If you wish to protect the engine over a longer

period than the normal lay up time, use Volvo Penta

emulsifying inhibiting oil, as it is specially designed

for the cooling water ducts. Follow the same proce

dure as above, but empty the system completely, as

the liquid does not offer any protection against frost.

Check that all plugs and drain cocks

are fully closed.

N.B. Some engines have zinc anodes on the plugs

and these act as sacriﬁcial anodes in the cooling

system. An anode must be replaced when about

50% of its volume has been used up.

COOLING SYSTEM

INHIBITING FRESH WATER COOLED ENGINES

Regular maintenance and servicing of the cooling

s stem is an effective wa of preventing damage

from overheating. It is also important to inhibit the

cooling s stem for the la -up season in order to

avoid frost damage and corrosion.

 Work on the cooling system is best carried out

on land. Otherwise there is a risk of water getting

into the boat.

The fresh water cooled engine has two cooling

s stems. The engine block and c linder head are

fresh water cooled. But the oil cooler, heat exchanger

and, on some engines, exhaust pipes, are sea water

cooled and should be inhibited in accordance with

the section on sea water cooled engines.

Check the freezing point of the coolant

with a hydrometer and top up the cooling

system if necessary. The coolant mixture

looses its corrosion protective qualities with time

and should therefore be changed every other year.

N.B. Avoid mixing different types of coolants since

it drastically diminishes the corrosion protective

qualities.

Do not mix coolant with other additives.

Check and clean sea water ﬁlter, if ﬁtted. Inhibit the

sea water cooled part of the engine in accordance

with the section on sea water cooled engines (see

page 7).

Check the level of the fresh water

system and make sure that all plugs

and draining cocks are fully closed.

N.B. Some engines have zinc anodes on the plugs

and these act as sacriﬁcial anodes in the cooling

system. An anode must be replaced when about

50% of its volume has been used up.

THERMOSTAT

If our instrument panel has a temperature gauge

ou will be able to see whether the engine sta s at

the right working temperature or not. Excessive

temperatures are often caused b blockage in the

coolant intake, cooling ducts or heat exchanger, or

b a defective impeller. Too low a temperature is

usuall caused b a fault thermostat.

Check the function of the

thermostat by removing it

and placing it with a ther

mometer in a pan of water. Heat the water and see if

the thermostat opens at the temperature indicated in

the operator’s manual. If not, replace the thermostat.
