Maintenance

Clean gauge by washing with fresh water to remove sand and salt deposits. Wipe off witha soft cloth moistened with water. The gauge may be scored or damaged if wiped withabrasive material (sand, saline or detergent compounds, etc.) or washed with solventssuch as trichloroethylene, turpentine, etc.

Multi-Function GaugeDip Switch Setting/Testing

NOTE: The multi-function gauge “Dip Switch” must be set on the back of gauge prior tooperation. Turn the ignition switch to the “OFF” position before setting dip switch. Thegauge will reset to selected settings when the ignition is turned “On”.

IMPORTANT: Test the gauge and related wiring BEFORE making final “Dip Switch”settings and BEFORE securing the gauge to dashboard of boat.

1. With the ignition switch in the “Off” position, set the multi-function gauge “Dip Switch”in (test) position as shown. (BLACK dot indicates switch position).

2. Turn ignition switch to the “Run” position. The multi-function gauge now is in the dis-play test mode. The gauge Temp, Batt, Oil, and Fuel red warning lights should be alter-nately flashing “On” and “Off”; the BLACK L.C.D. bar graphs should be cycling. (Thisindicates that all gauge functions are operational).

3. Turn ignition switch to the “Off” position. Reset the gauge “Dip Switch” to the correctoperating position for the outboard application.

2. Install fitting (b) into hole where plug (a) was removed from.

3. Connect the 44 in. long gray tubing (f) to fitting (b). Route the tubing out through thefront of the outboard.

4. Install coupler (g) onto end of tube. Insert the plug (i), barb fitting (h), or gauge tubing(j) into the coupler. NOTE: Barb fitting (h) is used for hose connection.

NOTE: An after market water pressure gauge may be connected to the engine, if existinghosing is not appropriate, by removing plug (a) or fitting (b) and installing a suitable barbfitting.

NOTE: Digital gauge speedometers use water pressure sensor (c) wired to the ECM. Ana-log gauge speedometers use BLACK Tubing (d) connected through adaptor fitting tospeedometer gauge tubing.

The system is activated when the oil in the engine mounted oil reservoir tank drops below50 fl. oz. (148 ml) You still have an oil reserve remaining for 30 minutes of full speed opera-tion.

NOTE: The engine mounted oil reservoir tank (located beneath the top cowl) along withthe remote oil tank will have to be refilled.

The OIL light (a) will come on and the warning horn sounds a series of four short tones.If you continue to operate the outboard, the light will stay on and the horn will sound fourshort tones every two minutes. The engine has to be shut off to reset the warning system.

The system is activated when there is an electrical failure of the oil pump or the oil pumpcircuit. Stop the engine as soon as possible. Continuing to operate the engine can resultin severe engine damage.

The OIL light (a) and CHECK ENGINE light (b) will come on and the warning horn will be-gin sounding. The warning system will automatically reduce and limit the engine speed.The engine has to be shut off to reset the warning system.

ENGINE OVERHEAT

aa

The system is activated when the engine temperature is too hot.

The TEMP light (a) will come on and the warning horn begins sounding. The warning sys-tem will automatically limit the engine speed to 3000 RPM. After the engine has cooled,shift the outboard into neutral to reset the overheat circuit.

IGNITION COIL, SENSOR, OR INJECTOR NOT FUNCTIONING

aa

The system is activated if an ignition coil, sensor or injector is not functioning correctly.

The CHECK ENGINE light (a) will turn on.

THROTTLE SENSOR NOT FUNCTIONING

aa

The system is activated if the throttle sensor is not functioning correctly.

The CHECK ENGINE light (a) will turn on and the warning horn will begin sounding.

WATER SEPARATING FUEL FILTER IS FULL OF WATER

a

The water level detection warning is activated when water in the water separating fuel fil-ter reaches the full level. The water can be removed from the filter.

The WATER DETECTION light (a) will come on and the warning horn will begin soundinga series of four beeps. If you continue to operate the outboard, the light will stay on andthe horn will sound every two minutes.

ENGINE OVER-SPEED PROTECTION SYSTEM

aa

The system is activated when the engine speed exceeds the maximum allowable RPM.

Anytime the engine over-speed system is activated, the warning horn (a) begins to soundcontinuously. The system will automatically reduce the engine speed to within the allow-able limit.

NOTE: Engine speed should never reach the maximum limit to activate the system unlessthe propeller is ventilating, an incorrect propeller is being used, or the propeller is faulty.

Guardian Protection System

The guardian protection system monitors critical engine functions and will reduce enginepower accordingly in an attempt to keep the engine running within safe operating parame-ters.

IMPORTANT: The Guardian System cannot guarantee that powerhead damage willnot occur when adverse operating conditions are encountered. The Guardian Sys-tem is designed to (1) warn the boat operator that the engine is operating under ad-verse conditions and (2) reduce power by limiting maximum rpm in an attempt toavoid or reduce the possibility of engine damage. The boat operator is ultimatelyresponsible for proper engine operation.

Guardian System Operation with Gauges

4 Function Gauge System will sound warning horn and illuminate ap-propriate light on gauge.

SmartCraft Gauge System will sound warning horn and display thewarning message.

Guardian System Activation

Condition Result

Engine Overheat Engine power level can be reduced to any per-centage down to an idle speed, if overheat condi-tion persists.

Air Compressor Overheat 2000 Model – engine power level can be reducedto any percentage down to an idle speed, if over-heat condition persists.2001 Model – no power reduced.

Block Water Pressure Low Engine power level can be reduced to any per-centage down to a fast idle, if condition persists.

Throttle Position Sensor Failure If the throttle position sensor fails or becomes dis-connected, power will be limited to a maximum ofapproximately 4500 rpm. When the TPS is in thefail mode, the ECM will use the MAP sensor for areference to determine fuel calibration.

Temperature Sensor (cylinder head and air com-pressor) Failure

If a temperature sensor should fail or become dis-connected, power will be reduced by 25%.

Battery Voltage (too high or too low) Battery voltage greater than 16.5 volts or less than10.5 volts will result in engine output power beingreduced. The higher or lower the voltage is outsideof these parameters, the greater the percentage ofpower reduction. In an extreme case, power couldbe reduced to idle speed.

Oil Pump Failure If the oil pump fails or an open circuit occurs be-tween the pump and the ECM, engine power willbe reduced to idle.
