11.6 Engine and propeller
The diesel engine must be made winterpoof. We recommend fitting a long hose on the nozzle
of the water pump, see Yanmar manual, preparing an anti-freeze mixture in a bucket and
letting the engine draw in this mixture until it comes out at the exhaust. In this way the engine
and the exhaust system will be protected from frost and corrosion.
NOTE
The zinc ring/magnesium ring (sacrifice anode) should be
renewed annually.
Note
During winter storage the propeller should be cleaned of any vegetation and be
inspected. If deformed, dented or nicked these areas must be repaired.
Subsequently it may be necessary to have the propeller balanced again.
11.6.1 Interval between engine servicing
Before starting the engine first time, please read the manufacters documentiotion. All further
information on the inboard Yanmar engine can be found in the documentation provided by the
manufacturer.
11.6.2 Exhaust system /Maintenance
The seawater cooled exhaust system with water collector, exhaust hose and swan neck is
winterproof and must not be emptied of water. The hose clamps should be tightened annually.
11.7 Electricity
Contacts should be free of corrosion and be firmly connected. Once a year you should check
all connection.
The battery needs special care. Even the fact that it is “maintenance-free” does not mean that
you can leave the battery connected on the boat in frosty conditions. Only a charged battery,
stored in a frost-free area and from time to time recharged, will work for years without trouble
