Re: What does BEEEWWW mean?
Is it PEEEWWWW or BEEEWWW? If PEEEWWWW you may have passed gas and the boat knows it. However, since you didn't post a model number I'm not sure if yours has the pass gas alarm.
It sounds like it's working fine and what you are hearing is the alarm letting you know it works as Silvertip stated. I know, it sounds sorta like it's dying and it's not a nice chirp but it is what it is. Think of your car, when you start it you see all the dummy light come on in the dash for a second or two to let you know they all work and you don't have a burned out bulb or something. The same principle applies here. It's letting you know the alarm itself works, I doubt more than that, so it's a good thing that you hear it. Now when you start the motor and hear it you can be assured the actual alarm works and your only concern, if any, is do all of the alarm sending units work like they should? Who knows?
