So i have a quick question. When i turn the ignition key, on my dash make a 2 beeping sound with 2 different tones and then stops after a second or 2. It always makes this sound before start up. All gauges show normal reading and it does not make any other noises besides that. Any idea? Thank you

The beeping at key up is considered normal as it's the warning system doing a self test telling you it's working correctly.

Also if you have a depth gauge (faria, hummingbird, etc.) mounted in the dash then some depth gauges may sound a beeping sound at first power up as well. http://www.iboats.com/Boat-Parts-Ac...earched.1--session_id.731992056?q=depth gauge
