I have a 95 mercury 40HP (serial#0G291100). My new purchase had an oil tank with about a cup of water in the oil tank. All is cleaned out, issues fixed and I know the oil injection is working. My questions are: 1. does this motor have an alarm if the OI stops working. The oil level alarm works...I was just wondering if there is something that tells you if the engine isn't get oil other than the tank sensor. 2. Is this motor's oil injection the "good" system that I have read about or the not so good version. Thanks to anyone who can/will take the time to help me out.
