Drain Cooling System
To protect the cooling system from rust and
damage from freezing, drain coolant from the
cooling system completely.
1) Remove the drain cocks, plugs and hoses
located as shown, and drain the coolant.

on the port side of the
cylinder block
¡

NOTE:
¡
When draining coolant, cover all electri-
cal parts and accessories with a plastic
cover to prevent them from getting wet.
¡
After draining the coolant, remove the
drain bolt on the bottom of the boat to
drain any coolant that has collected in the
bilge (provided the boat is on land). If the
boat is in the water, use a bilge pump in-
stead. After draining, rinse thoroughly
with clean water and dry.
¡
If possible, lift the front of the engine
slightly, so that the coolant water drains
completely from the cylinder block.
CAUTION:
DO NOT store the engine with water left in
the cooling system.
NOTE:
¡
After removing the hoses, if necessary,
drain any remaining coolant and seawa-
ter by bending, lifting or shaking the hose.
¡
If sand or other dirt clogs up a drain hole,
use a needle or similar tool to free it.
