CAUTION SYSTEM
The caution systems are designed to alert you to certain situations which may cause damage to your outboard motor.
Your outboard motor may become damaged if you rely on the Caution System to alert you to any malfunction that may occur or to give you an indication of the need for maintenance. To avoid damage to your outboard motor, regularly inspect and maintain it.
Continuing to operate your outboard motor with the Caution System activated can result in severe damage to your outboard motor. If the Caution System activates while you are operating your outboard motor, stop the motor as soon as possible and correct the problem or consult your authorized Suzuki marine dealer for assistance.
INDICATOR CHECK
Each time the ignition key is turned to the “ON” position, four lamps – the REV LIMIT 1, the OIL 2, the TEMP 3 and the CHECK ENGINE 4 in the monitor-tachometer will light briefly and the buzzer will also sound for the first two seconds, regardless of the motor conditions.
For the next three seconds, the monitor tachometer will indicate the total motor operating hours by means of the lamp flashing and needle indicating.
After this brief check period, the monitor tachometer will return to their stand-by mode and will only respond to motor conditions requiring a caution alert.
If the Caution System is not working properly, you may not be alerted to a condition that can cause damage to your outboard motor. If any of the four lamps does not come on or the buzzer does not sound when the ignition key is turned to the “ON” position, the lamps or buzzer may be broken or a failure may exist in the system circuit. Consult your authorized Suzuki marine dealer.
For checking the total motor operating hours, refer to the CHART OF TOTAL OPERATING HOURS INDICATION on the last page.
OVER-REVOLUTION CAUTION SYSTEM
This system is activated when engine speed exceeds maximum recommended speed for more than 10 seconds.
If this system activates, engine speed will automatically be reduced to approximately 3000 r/min. with red REV LIMIT lamp lit.
This system must be reset by moving the throttle to the idle position for about one second to restore full engine operation.
If the Over-Revolution Caution System activates at recommended maximum throttle and you are sure that the propeller pitch is sufficient and there are no factors like “over-trimming” or “ventilation”, there may be a problem with the Over Revolution Caution System. Consult your authorized Suzuki marine dealer if the Over-Revolution Caution System activates for no apparent reason.
OIL PRESSURE CAUTION SYSTEM
This system operates when the engine lubricating oil pressure drops below the correct level. If this system activates, the red OIL lamp will light and a buzzer will begin a series of beep. In addition, when this system is activated at 1000 r/min. or higher, engine speed will automatically be reduced to approximately 1000 r/min. with REV LIMIT lamp lit.
If you continue to run, the engine will automatically stop 3 minutes after beginning of the
above CAUTION system activation.
In case that the engine is automatically stopped due to the CAUTION system, the engine can be started again. However the CAUTION system will repeatedly activate until eliminating the cause.
If this system activates, stop the engine immediately, if wind and water conditions make it safe to do so.
If you attempt to remove or reinstall the motor cover while the engine is running, you may be injured. To check the oil level, stop the engine and then remove the motor cover.
Check the oil level and add oil if necessary. If the oil level is correct, consult your authorized Suzuki Marine Dealer.
Your engine may become severely damaged If you rely on the Oil Pressure Caution System to indicate the need to add engine oil. Check the engine oil level periodically and add oil as necessary
Operating the engine with the Oil Pressure Caution System activated can result in severe engine damage. If the Oil Pressure Caution System activates, stop the engine as soon as possible and add engine oil, if necessary, or otherwise correct the problem.
COOLING WATER CAUTION SYSTEM
This system is activated when the cylinder wall temperature is too high due to insufficient water cooling.
The cooling water caution system will not detect high combustion chamber temperature caused by, for example, an oil system malfunction, poor quality fuel, or spark plugs with an incorrect heat range.
If this system activates, the red TEMP lamp will light and the buzzer will begin a series of beep.
In addition, when this system is activated at 3000 r/min. or higher, engine speed will automatically be reduced to approximately 3000 r/min. with REV LIMIT lamp lit. If you continue to run, the engine will automatically stop 3 minutes after beginning of the above CAUTION system activation.
In case that the engine is automatically stopped due to the CAUTION system, the engine can be started again. However the CAUTION system will repeatedly activate until eliminating the cause.
If the cooling water caution system activates when operating, reduce engine speed immediately and check if water is being discharged from the pilot water hole. If no water is seen, fol low the procedures outlined below.
Water and wind conditions permitting, stop the engine, tilt it out of the water and remove any debris like seaweed, plastic bags or sand that may have blocked the water intakes.
Lower the engine into the water, being sure that water intakes are immersed, and restart it.
Check (A) that water discharges from the pilot hole and (B) that the red TEMP lamp is no longer lit.
Be aware that the red TEMP lamp may light again if engine temperature rises abnormally. If either of the above situations arises, consult your authorized Suzuki Marine Dealer as soon as possible.
If pilot hole water discharge is sufficient, buzzer and TEMP lamp may still operate until engine temperature decreases. Run engine in NEUTRAL only until the caution systems are cancelled.
Operating the engine with the Cooling Water Caution System activated can result in severe engine damage. If the Cooling Water Caution System activates, stop the engine as soon as possible, wind and water conditions permitting, and inspect the engine according to the above instructions. Consult your authorized Suzuki marine dealer if you cannot correct the problem.
Remember that the cooling water caution system cannot detect overheating caused by, for example, an oil system malfunction, poor quality fuel, or incorrect spark plugs.
If the engine is operated beyond the maximum trim position, the water intake holes may be above the water line. In this situation, the cooling water caution system may activate.
BATTERY VOLTAGE CAUTION SYSTEM
This system is activated when the battery volt age deficiency which could impair your motor’s performance occurs. If this system activates, the red CHECK ENGINE lamp will light and buzzer will begin a series of beep.
This system will be canceled automatically when the battery voltage restores to the proper voltage level. Refrain from using any electrical equipment such as P.T.T. system, hydraulic trim tabs, hydraulic jack plate, etc.
Failure to take proper precautions when inspecting or servicing the battery can be hazardous. Do not attempt to inspect or service the battery without first reading the warnings, cautions, and instructions in the “BATTERY INSTALLATION” section of this manual.
• A marginal battery may have enough power to start your engine, yet may still cause this caution system to activate whenever engine or boat accessory use places a high current demand on the battery. • If this caution system activates continuously, even after you have stopped using engine or boat accessories, contact your authorized Suzuki Marine Dealer.
