Hello,

On the front of your motor is a gear lube monitor bottle.

This square plastic bottle holds a reserve of gear lube for your sterndrive.

If the level in the bottle drops it will set off an alarm.

Check this bottle for the level of lube.

If you need to add lube make sure you use Mercruiser High Performance Gear Lube.

Keep an eye on the level. A drop in the level could indicate a leaking seal in your sterndrive. Every once and a while, especially after the drive has been serviced, the gear lube in the drive "burps" and the level in the bottle can drop.

If you suspect you have a leak make sure to have the drive checked ASAP and do not use the boat until it is fixed.

Let me know if this solves your problem.

hi all levels in all the bottles are at maximum , i topped the gear lube up as was halfway between min and max but still alarms intermittently , normally every 2 mins?
Marine Mechanic: Kenny, Marine Mechanic replied 12 years ago

OK... you might have a faulty sensor.

Disconnect the two blue wires from the bottle sensor (bullet connectors) and

install a jumper wire between the two wires.

If the alarm stops, the sensor/bottle assembly will have to be replaced.

If the alarm persists, let me know.

ok thanks will try tomrw and let u know! are the sensors prone to early failure then?

 

Marine Mechanic: Kenny, Marine Mechanic replied 12 years ago

Not really.

Might have a faulty oil pressure switch. This is down low on the port side of the motor. You might want to check the connections to the oil pressure switch too.
