oil warning horn question

LEVERETTE5 · #1 08-04-2008, 09:52 PM

I have a 2000 OX66 200 yamaha. This weekend while fishing my oil horn went off. There is a little circle on my gauge with a line thru it that was flashing at the same time. Both my main oil tank and my small tank on the motor were full of oil. I pulled the sensor out of the small tank and moved the float a few times put it back in and it was fine for about an hour and it did it again. I have looked in my repair manual and I did notice that there is a washer that should be on the bottom of the strainer that the sensor slides into on the small tank that is missing. Im not sure but it also appeared that the same strainer was not properly on the sensor( the repair manual has a picture of how it should of been. can any one tell me how to trouble shoot the oil system and what sensor would make the horn go off.the parts manager at pompano marine center said that the sensor in the small tank on the engine is the only thing that will activate the horn,is this true? Thanks Keith

Leverette,

PM sent.

I have a scanned version of the Yamaha Tech manual that describes the oil system, the tachs, the horns and how to trouble shoot it all. It was sent to me and was a great help. Way better than my over the counter book. Happy to pass it along.

Keith,

I wish I had the whole book but I only have the pages on the oil sytems. I sent them to your email.

I had issues with this on my old parker. follow the wire harness from the oil resevoir into the engine and check the connections there. they should be on the starboard side of the engine. A few of the connections would corrode and fall appart from time to time, and I would have to redo these connections sometimes.
