2. Place a 9.5 L (10 US qt) or larger container near the unclamped end of the hose.
3. With the assistance of another person, start the engine and adjust the speed to exactly 1000
RPM while holding the unclamped end of the hose on the connection on the engine. Remove
the hose from the connection on the engine and direct the water flow into the container for
exactly 15 seconds. At the end of 15 seconds, direct the water flow overboard, return the
engine to idle and stop the engine. Reconnect the hose to the engine.
4. Measure the quantity of water discharged into the container and compare with the
specifications given in the following chart.
5. Repeat the test four times to verify the results.

Cold Weather or Extended Storage
IMPORTANT: Mercury MerCruiser strongly recommends that this service should be performed by
an authorized Mercury MerCruiser dealer. Damage caused by freezing temperatures IS NOT
covered by the Mercury MerCruiser Limited Warranty.
Water trapped in the seawater section of the cooling system can cause corrosion or freeze
damage. Drain the seawater section of the cooling system immediately after operation or before
any length of storage in cold weather. If the boat is in the water, keep the seacock closed until
restarting the engine to prevent water from flowing back into the cooling system. If the boat is
not fitted with a seacock, leave the water inlet hose disconnected and plugged.
NOTE: As a precautionary measure, attach a tag to the key switch or steering wheel of the boat
reminding the operator to open the seacock or unplug and reconnect the water inlet hose before
starting the engine.
IMPORTANT: Mercury MerCruiser requires that propylene glycol antifreeze, mixed to the
manufacturers instructions, be used in the seawater section of the cooling system for freezing
temperatures or extended storage. Make sure that the propylene glycol antifreeze contains a rust
inhibitor and is recommended for use in marine engines. Be certain to follow the propylene glycol
manufacturer's recommendations.
Preparing Power Package for Storage
1. Fill the fuel tanks with fresh gasoline (that does not contain alcohol) and a sufficient amount
of Quicksilver Gasoline Stabilizer for Marine Engines to treat the gasoline. Follow instructions
on the container.
2. Check the antifreeze concentration. Refer to the Specifications section.
3. If the boat is to be placed in storage with fuel containing alcohol in fuel tanks (if fuel without
alcohol is not available): Fuel tanks should be drained as low as possible and Mercury/
Quicksilver Gasoline Stabilizer for Marine Engines added to any fuel remaining in the tank.
Refer to Fuel Requirements for additional information.
4. Flush the cooling system. Refer to the Maintenance section.
5. Supply cooling water to engine. Refer to the Maintenance section
