SERVICE IN CONNECTION WITH LAYING-UP AND
LAUNCHING THE BOAT, INHIBITING ENGINE AND REVERSE
GEAR
Idle engine for short periods of time, with the boat in the
water
In order to prevent damage to the engine caused by corrosion, the engine should be
run warm at least once every 14 days as long as the boat is in the water. If the boat is
not be used for over a month, a long-term inhibiting should be carried out.
Inhibiting for the winter lay-up
Prior to inhibiting the engine for the winter lay-up, an authorized Volvo Penta Service
Workshop should test the engine and equipment. It is advisable to check the
compression in order find out the condition of the engine. If the inhibiting work can be
made directly after the boat is out of the water, it is advisable to run the engine warm in
the water. This will facilitate the oil change.
INHIBITING SCHEME
Carried out with the boat on land
1
Change the fuel filter.
If an extra fuel filter is installed, drain water and impurities and
replace the filter insert.
Pump up fuel and vent the system. See “Venting the fuel system”,
page 23.
Check out the system for leakages.
2
Drain the cooling water from the engine and the reverse gear
(paragraphs 15 and 16, page 34). Check to make sure that the
water drains off, since impurities can block the cock. Then close
the cock and install the plug in the reverse gear.
3
Remove the suction line from the reverse gear (MD7A/MSB) and
from the cooling water pump (MD7A/110S). Install a hose with an
inner diameter 1/2” and insert the free end into a container with
fresh water. Make sure to have additional water at hand to fill the
container.
