If boat sits for two or more weeks , it has to run for an hour or so befor an intermitan beep ocurres.1984 merc 150 . If run a day or two later it only takes a few minuts . I have taken it to a mechanic with no luck . I changed the oil cap,some senser that cost about 200 bucks [not sure about the name]and another senser that plugs in by the oil cap plugs ,[it has one screw that holds it in , dont know the name of this one either ]. the motor runs great and uses about the oil it should . oil pump was checked and in good condition.What else is there ?The beep is fast .
