Engine Overheating (EFI Engines)
21195-1
If the engine overheats at high speeds, the engine
protection mode will activate and:
● Engine speed will be automatically reduced to
approximately 2500 or 3500 RPM, depending on
the severity of overheating. Mild overheating
results in a speed reduction to 3500 RPM. If an
engine alarm has been installed, an audible
warning horn will sound for 1/2 second every 5
seconds. More severe overheating results in a
speed reduction to 2500 RPM. If an engine alarm
has been installed, an audible warning horn will
sound once per second.
● The engine protection mode will remain active
until the engine has been reduced to idle and the
overheating problem has been corrected. For
additional information, see
Engine Protection
Mode
.
To determine possible causes for overheating:
● Look for obstructions to the water intakes (e.g.,
seaweed, plastic bags, etc.)
● Check impeller
● If fresh water cooled, check coolant level
● Check all water supply hoses for leaks
NOTICE!
Ignoring an overheating situation can cause
engine damage and/or equipment failure which may
not be covered by your warranty.
If the situation persists, contact your Volvo Penta
dealer for assistance.
Engine Overheating (Carbureted)
NOTICE!
Carbureted engines are not protected
against overheating! If the engine overheats, you must
take action to protect your engine.
If your engine overheats, the audible alarm will sound
and a temperature gauge on your instrument panel will
indicate your engine is overheating.
1.
If it is safe to do so, turn off the engine.
2.
Tilt the drive up and look for obstructions to the
water intakes (e.g., seaweed, plastic bags, etc.).
3.
Lower the drive unit.
4.
Start engine and run in NEUTRAL at 1500 RPM.
5.
Check the engine gauge to verify the condition.
6.
If overheating still occurs, do not operate the
engine unless it is an emergency. Only operate it
until you are clear of the emergency and seek a
tow to shore.
NOTICE!
Ignoring an overheating situation can cause
engine damage and/or equipment failure which may
not be covered by your warranty.
