Draining Raw Water Side of Closed
Cooling System Engines
1 With the engine turned off, locate and open the
drains on the exhaust manifolds (both sides of the
engine).
Do not drain engine block!
NOTICE!
Be sure that all water is drained from the
manifolds. If no water drains, use a piece of wire to
clear any obstructions from the drain holes.
NOTICE!
If possible, when draining the manifolds,
raise or lower the bow of the boat to keep the engine
level. This will provide for complete drainage of the
manifold. If the engine is not level, some water may
remain trapped.
NOTICE!
When draining the starboard manifold, take
care to direct the drained water away from the starter
to prevent water damage to the starter.
2 Loosen the hose clamps and remove the hoses
from the raw water pump.
3 Loosen the heat exchanger lower end cap. If pos-
sible, do not completely remove the screw. Loosen
enough to allow cap to separate from the heat
exchanger and water to drain. After water has stop-
ped draining, reinstall the end cap. Tighten screw.
4 Reinstall all hoses and secure all clamps in the
same orientation as removed. Reinstall and tighten
manifold drain plugs.
