Laying Up - Winterising - Beta Marine Beta 10 Operator's Maintenance Manual

WINTERISING AND LAYING UP
a) The engine lubricating oil and lubricating oil filter
should be changed at the end of the season rather
than in the spring. See section 2.
b) The closed circuit cooling system must contain an
anti-freeze coolant solution. The coolant solution is a
mixture of fresh water and anti-freeze (Ethylene Glycol
based conforming to BS6580:1992) with the anti-
freeze being a 50% solution (this also applies to
warm and tropical climates). The warranty is invalid if
the correct percentage/ratio is not used.
c) For cold climates where the air or water temperatures
can fall below 3°C, the sea water circuit must be
protected in addition to the fresh water system. This
is best achieved as follows:
•
Close the inlet seacock to the engine (engine
stopped).
•
Disconnect the sea water inlet pipe and dip it into a
small bucket containing 50/50 anti-freeze solution.
LAYING UP ASHORE
a) Change the engine oil before the boat is taken out of
the water. Remember that warm engine oil is much
easier to pump than cold!
b) Cooling system - As above in 'Winterising and Laying
up' paragraphs (b) to (f) should be followed.
c) If the engine is to be laid up for more than 6 months
then remove the sea water pump impeller.
d) If the engine will not be used or run for periods longer
than 6 months we recommend that the engine is
'inhibited' - this involves running the engine for about
5 minutes to:
•
Start the engine (out of gear) and run for 5 to 10
seconds until the anti-freeze is used up and can be
seen coming out of the exhaust outlet.
•
Shut engine off and reconnect the inlet pipe to the
seacock. The sea water or raw water circuit is now
protected by anti-freeze.
d) Ensure instrument panel is well protected and give
the key switch a spray of WD40 / Petroleum Jelly or
equivalent.
e) With the engine stopped, disconnect the battery
(always disconnect the negative cable first and re-
connect the negative cable last) and take it ashore for
trickle charging and top up as necessary. If AC power
is available then this can be done on the boat.
f) Fuel tanks should be kept full during the lay up
period to eliminate water condensation in the tank.
Water entering the fuel injection system can cause
considerable damage.
•
Replace all the diesel fuel in the fuel system and
injection pump by running the engine with 'calibration
fluid' (fuel pump test oil ISO 4113).
•
Allow 'Ensis' to circulate around the lubricating oil
system by draining out the standard lubricating oil
and replacing it with a rust preventative oil such as
'Ensis' or similar.
