C. Temperature Gauge (4-in-1 Gauge)
Figure E5: Tachometer - Rear View
The temperature gauge included in the 4-in-1 gauges
monitor the cooling system of the engine. Asudden in-
crease in the temperature could be a signal of a blocked
cooling passage or a water pump malfunction.
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 (speedo tube) that con-
nects it to the speedometer gauge on the dash. See
Figure E6. The pitot tube extends below the hull. Water
strikes the tube inlet and creates positive pressure. The
faster the boat speed, the greater the pressure, and the
higher the speed indication on the speedometer.
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 (4-in-1 Gauge)
The oil pressure gauge indicates the pressure in the en-
gine lubrication system. A significant drop in oil pres-
sure is a possible indication of an oil pump or other leak-
age problem.
If 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 in-
formation.
