    Mercruiser 4.3 alarm won’t stop

    Thanks to all for your heLo! Found the gear oil header tank empty and a mass of black oil goop in the bottom. Cleaned and reinstalled tank, filled the tank with 90wt marine gear lube, and alarm has been silenced. Tested the boat for the first time today and she ran perfect. Thanks to all of you!😎
