Figure E6: Speedometer
NOTICE
Speedometers are not precision instru ments.
The indications are relative and should never
be used for navigational purposes or similar
critical situa tions.
DO NOT rely on the speedometer when trying
to achieve a “NO WAKE” condition in a harbor
or other enclosed water way. ALWAYS reduce
throttle! Speed ometers are not effective at
mea suring low opera tional speeds. You are
responsible for damage caused by the wake of
your boat.
The speedometer is a water pressure sensitive unit.
It has a pick-up (pitot tube) assembly mount ed in the
outdrive assembly and a spee do tube connecting it
to the speedome ter gauge on the dash. Water strikes
the tube inlet and creates positive pres sure. The faster
the boat speed, the greater the pres sure, and the
higher the speed indica tion on the speed ome ter.
C. Temperature Gauge (4-in-1 Gauge)
The temperature gauge (included in the 4-in-1 gauge -
Figure E7) monitors the cooling system of the engine.
A sudden increase in water temperature could be a
signal of a blocked cooling passage or a water pump
malfunction.

NOTICE
Operation of an over heat ed en gine can re sult
in en gine sei zure. If an un usu ally high tem pera-
ture read ing oc curs, shut the en gine off im me-
di ately.
D. Oil Pressure Gauge (4-in-1 Gauge)
The oil pressure gauge (included in the 4-in-1 gauge
- Figure E7) indicates the pressure in the engine
lubrication system. A significant drop in oil pres sure is
a possible indication of an oil pump or other leak age
problem.
The engine has been equipped with an audible engine
alarm, the alarm should sound if the oil pressure drops
below the normal operating range of the engine. Please
see your engine owner’s manual for specific engine
information.
NOTICE
Operation of an engine with ab normal ly low oil
pressure can lead to engine dam age and pos-
sible seizure. Have the en gine ser viced imme-
diately upon a re duced oil pressure indication.
E. Voltmeter (4-in-1 Gauge)
The voltmeter (included in the 4-in-1 gauge - Figure
E7) monitors battery condition and thus alternator
performance. See Section H for addi tional information
regarding electrical systems.
