I have a 2005 Nautic Star Dc 205 Sport Deck boat with a 2005 Yamaha 115 outboard, I have had this boat for about two months now and it has always started with the hit of the key, but now there is a strange solid buzzer going off under the dash. For a while the buzzer would come on occasionally and when it did the boat would crank over fine, but wouldn't start, wait a few minuets and turn the key on and if the buzzer wasn't there it would start like normal. Now the buzzer is there all the time now and it just cranks over and will never start as long as that buzzer is on. We have contacted all our local dealers, but no one can diagnose the problem. Please help.
