ENGINE VENTILATION
Ventilation systems are required for gasoline engine
compartments. Your boat features a set of deck vent
shrouds which supply a consistant amount of air to the
engine compartment. Powered blower motors connected
to ducts in the lower one third of the bilge evacuate
contaminated air to the atmosphere. Understand the
following warning!
It is important that you read the propulsion manufacturer’s
manual carefully and become familiar with the operation
as well as necessary maintenance on the drive train
components. Pay careful attention to the sections on
winterization if you live in freezing climates. Extensive
damage can result if proper winterization is not followed.
Refer to the maintenance section of this manual for more
information or call your nearest Regal dealer.
AUDIBLE ALARMS
Selected engines use audible alarms. They are designed to
use sensors which pick up deviations from the normal
operating parameters. Oil pressure and temperature sensors
send a signal to a buzzer under the dash which sounds a
high pitched alarm indicating a possible problem. In
addition to the dash, some engines use buzzers at the engine
itself. On start up it is not unusual to hear an audible alarm
sound when cranking the engine over. This occurs normally
because it takes a second or two to build up the engine oil
pressure. Then the alarm will stop.
A seasoned skipper monitors his instrument panel often
while cruising.

PROPULSION
STERN DRIVES
Check the intake and exhaust (ducts) vents periodically
for debris build up. They are located on both aft sides of
the deck. See photo. When in the bilge make sure you do
not step on the black bilge blower hoses.
Ensure that the hose runs are sloped at a constant down-
ward angle to prevent any water trapping.
