2011 Mercury Optimax 150 4 beeps

[GreggC]

I couldn't find a old thread on my problem so I hope someone can help. I have replaced the old reservoir on the motor with a new one, also changed fuel filter and I'm still getting 4 beeps every 2 minutes. The mechanic ran it on Dino and couldn't get it to beep. Brought back to the lake ran it and the 4 beeps started again, loosened cap to make sure it didn't need purging and oil came out. Still 4 beeps every 2 minutes but runs fine. Could the alarm system be bad since I put a new tank on and change the fuel filter?

Thanks, but I have already tried purging the tank again, it is full and I have changed the fuel filter didn't seem to have any water in it. Doesn't do it on the Dino only when I put it in the water under load of the boat. I appreciate your comment to the thread.
