Draining Raw Water Side of Closed
Cooling System Engines
1. With the engine turned off, locate and open all
drains located on the manifolds on 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 mani-
folds, 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. After the water has completely drained, reinstall
the drain plugs and tighten securely.
3. Loosen the hose clamps and remove the hoses
from the raw water pump.
4. Loosen the heat exchanger drain cap (located on
the bottom of the heat exchanger) and allow
water to drain. After water has stopped draining,
reinstall the drain cap.
5. Loosen clamp C and remove hose D from fuel
pump. Allow water to drain from hose.
Reinstall all hoses and secure all clamps in the
same orientation as removed.
