Hoping someone out here can help, was on Truman yesterday ( Friday ) went up to u from Bucksaw, running about 30 mph, got to where the river makes a right turn and a buzzer went off, wasn't sure what it was ( either water pump or oil ) stopped motor immediately, checked oil res it seemed low, started back up no beep. Figured I was low on oil and went back to Bucksaw and bought a gallon of oil, turns out I had half of a container already, so I poured the gallon in anyway, now it's full..Went back towards u and at the same place buzzer went off again...watched motor when I was going and water pump was putting out a good stream. I shut it down again and wasn't sure what I should do, so I decided to head for u, never heard another sound till coming back and about the same spot it did it again. Stopped motor, waited a minute or two started up again and went to cedar creek and fished, that was the end of the noise for the rest of the day.. Anyone have any Idea's.
