Hello everyone: My boat just starting beeping 6 successive (very loud) beeps about 5 min after I start the boat. This is not the regular startup alarm before starting the boat. I noticed that the gas gauge was on "E" so I thought it was an alarm for low fuel so I put 10 gal of gas in it. The gas gauge did not budge and still on E and the 6 beeps did not go away. Other things I have done recently before I noticed the beeps: I changed the lower unit gear oil and put the battery on trickle charger for the winter. Interestingly, the beeps come on even when the key is in but the boat is not started. Any ideas what these beeps mean?
