After Engine Shutdown
Engine Flush
Volvo Penta engines incorporate an engine flushing
port designed to flush the engine with fresh water while
the engine is running. Flushing the engine with fresh
water after each use will increase the longevity of com-
ponents.

NOTICE! If flushing the engine with the boat in the
water, do not run higher than idle speed or sea water
may be drawn in with the fresh water.
NOTICE! When flushing the engine with the boat in the
water, fresh water pressure must be 17 psi (117 kPa)
or greater.
1. If the engine is running, shut it down.
2. Remove the blue plastic cap from the hose that is
clamped to the starboard side of the engine. It is
marked with the running engine flush symbol
1 .
3. Connect a water hose from a fresh water source
to the flush connector on the engine
2 .
4. Turn water on full and start the engine.
5. 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.
6. After engine is flushed, shut down the engine.
NOTICE! Drain the engine if freezing temperatures are
expected. For details on draining the engine see: Draining
the Engine .
7. Disconnect water hose and reinstall the cap.
NOTICE! When re-installing the blue cap on the fresh
water flush hose, tighten it by hand, then tighten 1/4
turn using a wrench. If the cap is too loose, air may be
sucked in, causing the engine to overheat, resulting in
damage.
Drive Position, When Not in Use
When the boat is not being used the drive should be
trimmed to the full down or vertical position. Do not
leave the drive in the tilt position for long periods of
time.
