As noted above 20 year old Merc 2 cycle continues to alarm but mechanic says because showing smoke when running should be ok for now. Need new mechanic. Same thing happened last year and mechanic resolved by changing large remote oil reservoir cap and oil alarm sensor. Continuously beeping now and not comfortable using. Is there a pump somewhere pushing oil to motor annd how to test it? Other thoughts or suggestions?

Hi. Firstly, it could be a low oil alarm meaning that your supply tank in the bilge is low on oil. Or other low oil associated fault with the tank under the hood.
Secondly, if this is one of the older 2.0 v6 2 strokes, you will want to do away with that oil injection system asap. Notorious for failing. Surprised it has t already
