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. Thefastertheboatspeed,thegreaterthepres-

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.
If the pick-up becomes clogged, the speedometer will not
register. Cleantheopeningwithapieceofwireordiscon-

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-
sibleseizure.  Havetheengineservicedimmedi-
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.
