Some engines are equipped with devices that limit en-
gine rpm in accordance with the oil pressure or engine
temperature. Refer to the Engine Owners manual for
additional information.
The tachometer must be set for different engines installed.
The tachometer setting screw or knob is located on the
backside of the gauge. See Figure B5. The tachometer
should be set according to the information in Table I.

B. Speedometer
The speedometer is a water pressure sensitive unit. It
has a pick-up (pitot tube) assembly mounted on the tran-
som and a small plastic hose that connects it to speed-
ometer gauge on the dash. The pitot tube extends below
the hull. Water strikes the tube inlet and creates positive
pressure. The faster the boat speed, the greater the pres-
sure, and the higher the speed indication on the speed-
ometer.
If the pick-up becomes clogged, the speedometer will not
register. Clean the opening with a piece of wire or discon-
nect the tubing and blow out the pick-up with compressed
air
When winterizing the boat, the speedometer tubing must
be drained of water. Disconnect the speedometer hose
at the pick-up assembly and at the gauge and blow
through the tubing to remove the water.
Speedometers are not precision instruments. The indi-
cations are relative and should never be used for naviga-
tional purposes or similar critical situations
NOTICE
DO NOT rely on the speedometer when trying to
achieve a “NO WAKE” condition in a harbor or
other enclosed waterway. ALWAYS reduce
throttle! Speedometers are not effective at mea-
suring low operational speeds. You are responsi-
ble for damage caused by the wake of your boat.
C. Temperature Gauge
The temperature gauge monitors the cooling system of
the engine. A sudden increase in the temperature could
be a signal of a blocked cooling passage or a water pump
malfunction.
NOTICE
Operation of an overheated engine can result in
engine seizure. If an unusually high tempera-
ture reading occurs, shut the engine off immedi-
ately.
D. Oil Pressure Gauge
The Oil Pressure Gauge indicates the pressure in the
engine lubrication system. A drop in oil pressure is a
possible indication of oil pump or leakage problems.
NOTICE
Operation of an engine with abnormally low oil
pressure can lead to engine damage and pos-
sible seizure. Have the engine serviced immedi-
ately upon a reduced oil pressure indication.
E. Voltmeter
The voltmeter monitors battery condition and thus alter-
nator performance. See Section E Electrical Systems
for additional information on voltmeter operation.
F.
Fuel Gauge
The Fuel Gauge displays the level of fuel that is present
in the fuel tank. Refer to Section E Electrical Systems
and Section F Fuel System for additional information.
