Owner's Manual DF9.9 Over-Revolution Limiting System
Check the oil level and add oil if necessary. If the oil level is correct, consult your authorized Suzuki Marine Dealer. To inform you that the oil pressure caution lamp is working, it will come on for a few seconds after the engine starts. If the lamp does not come on, stop the engine and consult your authorized Suzuki Marine Dealer. If the lamp stays on, check the engine 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.
OVER-REVOLUTION LIMITING 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. 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 Limiting 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 Limiting System. Consult your authorized Suzuki marine dealer if the Over-Revolution Limiting System activates for no apparent reason.
