1. Remove the drain plug or sensor from each side of
the engine.
Figure 7.6 – Anti Knock Sensor
NOTICE
Some 5.7 Liter engines have a knock sensor
located in the drain location. The knock sen-
sor and knock sensor stud must be carefully
removed to drain that side of the block.
NOTICE
On the 8.1 Liter engine, removing the knock sensor
does NOT drain the block. Remove the plugs from the
brass fillings on both sides of the engine to drain
water from the block.
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.
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.
