2007 VE alarm or humming sound

[mullinsd]

Recently bought a 2007 VE with 133 hours on it.. I have taken it out a few times and each time noticed a high pitch alarm/sound under the dash when the boat key is turned on.. Not load or overly noticeable, but I can hear it.. Any thoughts to what this might be? I have tried to pin point the source but am having a hard time..I am certain is is under the helm.

Any help would be appreciated..

When the boat is keyed to on, its normal for the sounder to sound until the engine is started. your sounder could be sic. Does is stop when the engine is fired? Could also be a stereo issue and its the sub thats humming. Put your hand on the sub and see if you feel what your are hearing.
