[loadmaster6119]

I have a yamaha 50 four stroke 98.
Ran fine all of a sudden the oil light comes on and I here the warning buzzer.
oil-checks ok
intakes are clear?
motor starts bat adding a few RPMS starts to stutter?
cooled and restarted a few times, oil warning will not go away?

That is signaling low oil pressure, once warning is activated the buzzer will sound and engine rpm's will reduce to 2000 rpm's. Have the oil pressure checked.
