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
5.4.8 Changing the fuse
The fuse box included in the electrical system is mounted on the electrical unit. The fuse will disconnect
the electricity supply if it is overloaded. You can reconnect the circuit by wiring up to the next terminal.

Laying up and launching
6.1
Inhibiting
While the boat is in the water but not in use, the engine should be run warm at least once every 14 days.
If the boat is not to be used for over a month at a time, long-term inhibiting should be carried out.
6.2
Long-term inhibiting
You should have the engine and its accessories checked by professional before carrying out long-term
inhibiting, and see that any necessary repairs are carried out at this point.
6.3
Inhibiting schedule (with boat in water)
6.3.1
Allow the engine to idle at high revolutions for a few minutes. Then stop it.
6.3.2
Pump all oil out of the engine using the oil pump and drain off the oil out of the gearbox.
6.3.3
Change the oil filter. Fill the engine and gearbox to the correct level. The engine is then ready
to run on this oil next season. When inhibiting for longer periods than normal laying-up for the
winter, special preservative oil should be used, and the oil filter should not be changed until the boat is
launched again.
6.3.4
Change the fuel filter
