WARNING
!
Rotating propellers can cause serious injury or death. Never
operate the boat out of the water with a propeller installed. Before
installing or removing a propeller, place the drive unit in neutral
and engage the lanyard stop switch to prevent the engine from
starting. Place a block of wood between the propeller blade and
the anti‑ventilation plate.
NOTICE
Operating the engine out of the water at high speeds creates
suction, which can collapse the water supply hose and overheat
the engine. Do not operate the engine above 1400 RPM out of the
water and without sufficient cooling water supply.
To prevent silt and salt buildup in the cooling system, flush with
freshwater.
1. Install a flushing hose from a water tap to the flushing
connector. Consult your boat owners manual for the location
of the flushing connector.
2. Completely open the water tap. Place the remote control in
neutral position and start the engine. Operate the engine at
idle speed, in neutral, for about 10 minutes or until discharge
water is clear. Stop the engine, shut off the water, and remove
the flushing hose.

ORROSION AND ORROSION ROTECTION
Whenever two or more dissimilar metals (like those found on the
sterndrive) are submerged in a conductive solution, such as
90-8M0098854 MARCH 2015
saltwater, polluted water, or water with a high mineral content, a
chemical reaction takes place causing electrical current to flow
between metals. The electrical current flow causes the metal that is
most chemically active, or anodic, to erode. This is known as
galvanic corrosion and, if not controlled, it will in time cause the
need for replacement of power package components exposed to
water.
Refer to the Quicksilver booklet, Everything You Need to Know
About Marine Corrosion for more corrosion information.
NOTICE
Using magnesium anodes in salt water causes an electrochemical
reaction on the metal surface of the drive, resulting in corrosion
damage from the paint blistering and peeling off the drive. Use
magnesium anodes in fresh water only.
