Draining Raw Water Cooled Engines
51721
1.
With the engine turned off, locate and open all
drains located on both sides of the engine. Raw
water drains are blue, hardened plastic plugs.
NOTICE!
Be sure that all water is drained from
the engine. If no water drains, use a piece of wire
to clear any obstructions from the drain holes.
NOTICE!
If possible, when draining the engine,
raise or lower the bow of the boat to keep the
engine level. This will provide for complete drain-
age of the block and 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.
