    Oil alarm went off today.

    2008 mercury 200 opti # 1B528560
    I dropped it in the water fired it up let warm for a bit popped it into reverse and alarm went off. I looked at the smart gauge it showed the bell,engine and oil icons. First time this has happened. I shut it off and hooked my phone to vessel veiw. The fault said the tank on the motor was low on oil. I pulled the cowl and the tank was full. I checked the main tank it had about 1 and 1/4 gallon in it. I looked at the lines running to th oil pump all where full. I looked for leaks nothing. Left the cowling off and started it it took about 15 secs until the alarm went off again. I double check every thing had oil. I did not turn in on again. When I got home I topped off the main tank check the motor tank and looked even closer for a leak Nothing. Can someone point me in the right direction. I watched some videos but they are saying they had 4 beeps mine did not do that it never stopped.
    Thanks

    Replace tank and sensor so you're done with it.

    Oil Pump Prime Sequence should be run on a suitable diagnostic tool.
