Remove the longer cooling hose (1) from the thermo-
stat housing, then bend the hose down so that it emp-
ties completely. Remove and empty the thicker coo-
ling hose (2) from the circulation pump. Remove the
drain plug (3) at the exhaust pipe, then clear the hole
of any impurities using steel wire so that the water
1
can run out freely. Remove the drain plug (4) from the
cylinder block, then clean the drainage hole. Remove
both hoses (5) from the seawater pump and drain
them. Turn the engine over on the starter motor for a
second (do not allow the engine to start!) so that
the water remaining in the seawater pump comes out.
Refit all the hoses and drain plugs. Check the tight-
ness of all the hose clips. Do not forget to open the
2
seawater cock (if fitted) before starting the engine
again.
