2003 Optimax 225, my Merc smart gauge was telling my oil was low even though it was actually full. i was told to replace the reserve oil tank under the cowling so i did, bled the lines just like your supposed to. But its still telling me that my oil tank is low. The big oil tank is full. I double checked the new one by turning the cap a little and oil started come out so its still full. Ive been told its the main tank and I just need to turn off the sensor in my smart gauge under Calibration. Does anyone know how to do this?
