The rear deck lid to the bilge/battery area in my 96 Eyra is wired with the alarm system. Was with my 97 PII as well. Not sure about the new boats, but I would think so. Lift the lid, enjoy the noise! If you need to get in the bilge in an emergency…fire, broken pump, etc… probably dont want it locked.
