Warning Horn Activates (With Power Loss)
POSSIBLE CAUSES
•
Intermittent horn sound:
• The oil level in the engine‑mounted oil reservoir tank is low. Refill the
reservoir tank and the remote oil tank. Refer to
Fuel and Oil
for
details.
• Battery voltage is out of limits.
• Throttle position sensor failure.
•
Continuous horn sound:
• The oil level in the engine‑mounted oil reservoir tank is critically low.
Refill the reservoir tank and the remote oil tank. Refer to
Fuel and Oil
for details.
• The oil pump has failed, halting the oil supply to the engine.
• Engine speed exceeds the maximum‑allowable RPM. The system
limits the engine to within the allowable range. If the overspeed
condition continues, Engine Guardian places the engine into power
reduction. Overspeed may be caused by incorrect propeller pitch,
engine height, trim angle, etc.
• High engine temperature or low block water pressure.
• Cooling system clogged.
• Incorrect transom height (water pickups not getting adequate water
supply).
Warning Horn Activates (No Power Loss)
POSSIBLE CAUSES
•
Warning horn activates on start up. This is normal operation.
