Engine Flush
Volvo Penta engines incorporate an engine flushing port de-
signed to flush the engine with fresh water while the engine is
running. If flushing the engine with the boat in the water the
engine should not be run higher than idle or sea water may be
drawn in with the fresh water.
• If the engine is running, shut it down.
• Remove the blue plastic plug from the engine
flushing port.
• Connect a water hose from a fresh water source to
the flushing port.
• Turn water on full and start the engine.
• Let engine idle until engine temperature stabilizes
at its normal operating range. This will allow the
thermostat to open and ensure the fresh water
circulates throughout the engine.
• After engine is flushed, shut engine down.
• Disconnect water hose and reinstall the cap.
Drain the engine if freezing temperatures are expected.

General
Most countries have introduced legislation controlling the
use of antifouling agents. In some cases these agents are
completely forbidden for use on leisure craft.
In these
cases ask your Volvo Penta dealer for advice about
alternative methods.
IMPORTANT! Find out what regulations apply to the use of
antifouling agents.
Underwater Hull
Anti fouling agent containing copper oxide can increase
the risk of galvanic corrosion and therefore should never
be used.
