NOTICE
Placing the drain plugs in a plastic bag and attaching
it to the steering wheel of the boat will act as a
reminder to reinstall the drain plugs during recommis-
sioning in spring.
1. Remove the drain plug or sensor from each side of
the engine.
Figure 7.9 – Anti Knock Sensor
NOTICE
Some 5.7 Liter engines have a knock sensor
located in the drain locations on both sides of
the engine. The knock sensor and knock sen-
sor stud must be carefully removed to drain that side
of the block.
NOTICE
On the 6.0 and 6.2 Liter engines, removing the knock
sensor does NOT drain the block. Remove the caps
from the brass hose fittings on both sides of the
engine to drain water from the block.
2. Use a short piece of stiff wire and poke around in the
drain hole to ensure that any rust or scale is broken
apart, and the engine drains completely.
3. Disconnect the large diameter hose that runs from
the water-circulating pump to the thermostat housing.
Make sure all of the water drains from the hose.
