Repair Difficulty
Easy
Repair Time
30 to 60 mins
Used Crowley for years, since before they sold online and they always had the best prices and the best people in the store. Online shopping with them has proven to be just as good of an experience. I always recommend them for parts and service.

Problem fixed: low oil sending unit stuck on creating alarm from control panel

The engine 2-stroke oil tank has a low oil sensor in the bottom of it and can't be replaced without replacing the whole tank. If you have a steady alarm going off but the oil is not low it is most likely the oil sending unit. You can check this by locating the 2 blue wires coming from the bottom of the oil tank and disconnecting them, you will most likely have to drop the lower cover to reach the connectors. If the alarm goes out when you disconnect them then the sensor is bad. You can test the continuity of the 2 wires from the sensor with a multi-meter, if the tank is full and there is continuity between the 2 wires the tank will have to be replaced. Replacement is all-in-all an easy repair, hardest part is dumping the oil out after the bolts for the tank have been removed!
