Hoping to get some help as I'm new to this forum as well as the engine!
I have recently purchased a 1998 Mercury 150 Outboard (Offshore). I have a long (continuous) alarm that will go off after running the boat at 3 /4 ? full throttle for longer than 5-10 minutes. I can run the boat at low speed (trolling speed) for well over 2 hours with no problems whatsoever. When the alarm goes off, I put the boat in neutral and within 10 seconds the alarm goes off. It also seemed the alarm would shut off when I took the Oil Reserve Tank cap off (I?ve checked the sensor in the oil tank and seems to be working correctly). Then again, that could be because it takes me longer than 10 seconds to take the cowling off and get to the oil reserve tank.... I've read that the short beeps are oil and the longer (continuous) beep is a temperature issue. Is this correct?
Is there a reason why at low speeds I have no issues and at ?-Full throttle it alarms (again after 5 min. or so of running).
I?m thinking I need to replace all the hoses from the oil pump that seemed old and not terribly pliable (which may be causing a vacuum leak when run under full load) not allowing sufficient oil when running under high speed? Other friends have suggested it may be a temperature sensor that may need to be replaced.
I?ve bled the oil pump lines, which did not help resolve the issue.
Water seems to stream out the back of the engine steadily ? it also appears the water box/impeller is working correctly. Again, the issue seems to be only when run hard -- when running at low speed I have no problems. Any thoughts, suggestions on what to look for to resolve the issue would be very much appreciated!
