OS 285

Tachometer

The tachometer displays the speed of the

engine in revolutions per minute (RPM). This

speed is not the boat speed or necessarily

the speed of the propeller. The tachometer

may not register zero with the key in the

“OFF” position.

Speedometer

The speedometer indicates the speed of the

boat in miles per hour. Most speedometers

measure the water pressure against a small

hole in the pickup tube located in the lower

engine unit or mounted on the bottom of the

transom.

Temperature Warning

The temperature warning indicates the tem-

perature of the engine. A sudden increase in

the temperature may indicate an obstructed

water inlet or an impeller failure.

Fuel Gauge

The fuel gauge indicates the amount of fuel

in the fuel tanks. This gauge is an approxi-

mate indication of fuel remaining and is not a

calibrated instrument.

Voltmeter

The voltmeter displays the voltage of the

battery and the charging system. Normal

voltage is 11 to 12 volts with the engine(s) off

and 13 to 14.5 volts with the engine(s) run-

ning.

Hour Meter

The hour meter keeps a record of the oper-

ating time of the engine.

Tilt/Trim Gauge

The tilt/trim gauge monitors the position of

the outboard engine. The upper range of the

gauge indicates the tilt, which is used for

shallow water operation and loading the

boat on a trailer. The lower range indicates

the trim position. This is the range used to

adjust the hull angle while operating your

boat on a plane. Refer the engine owner’s

manual for more information on the opera-

tion of the outboard power tilt and trim.

Engine Alarms

Most outboard boats are equipped with an

audible alarm system mounted at the helm,

monitoring selected critical engine systems.

An alarm will sound if one of these systems

begins to fail. Refer to the engine owner’s

manual for more information on alarms

installed with your engines.

! CAUTION

Never exceed the maximum recom-

mended operation RPM of the engine.

Maintaining maximum or close to

maximum RPM for extended periods

can reduce the life of the engine.

! CAUTION

Continued operation of an overheated

engine may result in engine seizure. If

an unusually high temperature read-

ing occurs, shut the engine off imme-

diately. Investigate and correct the

problem before starting the engine

again.

! CAUTION

If an engine alarm sounds, shut off the

engine immediately. Find and correct

the problem before using the engine

again.
