I was told that if I remove the float on my Merc 200 HP EFI on the tank located on the motor that I should hear a alarm go off. I tried this evening and I didn't get any warning what so ever. I've never had a motor that had a warning alarm for low oil. Is this procedure indeed suppose to work? Thanks for any information. I tried with the key in the on position and with the master switch on, still no warning alarm..
