Sounds like an oil warning sensor gone bad.

My optimax used to do that until it flushed(peeing) Is yours flushing when the tilt is down or just up.

Yes it keeps beeping all the time as long as the motor is down.
when I tilt it up and out of the water, it stops beeping
thank you

Is the sensor you are talking about in the oil tank or in the reservoir on the motor itself?
Thank you

I'll agree on the oil sensor and I'd bet the oil tank is in the engine.
