I have a 40 HP Mercury that I need the year for. Serial Number 0G058744. Also took boat out for first time<br />this year and Beep, beep, beep alarm came on (not steady), figured out it was an oil problem alarm, changed<br />level indicator in tank, still the alarm was on, changed the oil alarm module(black box), still alarm sounded. Was<br />wondering if anyone has any ideas, maybe oil injector tied to alarm system? Also can not find oil pressure switch.

1994.<br /><br />May I suggest you get a manual for the other issue?

I had an oil alarm problem on my 150 merc and couldn't figure it out, I think my pump wasn't turning at the right ratio. Anyway I decided to plug the system (20bucks) and pre-mix my gas. This way I know I'm getting oil in the cyclinders. If your alarm is sounding don't run it, find the cause of the problem. All may apear functioning when it's not, end result BLOWN MOTOR. Let us know what you found.<br />Good luck.<br />CU
