4.1 Frost Risk If the engine is fitted with a fresh water cooling system, it should be filled with a 50:50 mixture of anti-freeze and water, or alternatively drained off. 4.2 Draining off fresh water systems To drain off the fresh water cooling system, open the cock on the side of the engine block. 4.3 Draining off sea water systems Unfasten the cover on the sea water pump. -
Page 12: Check Every 14 Days
5.1.2 Check water cooling level (Fresh water systems) Check every day before starting the engine, you open the cap of filler that the water level can be found from this filler. When necessary, fill up with fresh water or corrosion inhibitive anti freeze mixture. When there is a danger of frost it is important to ensure that the fresh water system is filled with anti freeze. -
Page 13: Service Every 50 Hours Of Operation
5.3 Service every 50 hours of operation 5.3.1 Change oil filter Run the engine until it is warm. Pump up the oil through the hole for the dipstick, and then refill with oil to the correct level. See: “Technical Data” for type of oil to be used. Note: The oil filter should be changed at the same time as every second change of engine oil. - Page 14 5.4.4 Check/change the impeller The impeller may become damages, for example through lack of water in the pump due to blocked intake. Close the bottom cock. Then remove the pump cover and inspect the impeller. If it has been damaged it should be replaced.

5.4.7 Check cooling system If the cooling system is functioning normally, the “TEMP” lamp will not be lit up. If the temperature is too high and the lamp lights up, the cause maybe one of the following: Blocked water intake Defective impeller in sea water pump Defective thermostat or temperature gauge Warning: Watch out for water leakage whenever you are working on the cooling system... - Page 16 6.3.5 Clean the filter screen and vent the fuel system 6.3.6 Loosen the venting screw on the fuel filter about 4 turns. Watch out for fuel splashing. 6.3.7 Pump up the fuel using the hand primer until the fuel is flowing out free of air bubbles. Tighten the venting screw again.
- Page 17 Check that fuel is reaching the injectors by unscrewing the pressure pipe on the injector, and then turn the engine over using the starter motor. If no fuel appears it may mean that the filter is blocked, the fuel pump is defective, or that there is air in the system. Change all the filters and vent the system. If not fuel appears after this, either the feed pump or the injector pump maybe defective.
