Hi Brad and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, post back with clear pictures of these solder points / connection holes. Please click HERE.
Hi again Brad,
Basically yes; as the Furuno Sounder FCV-261 was originally shipped at 18-40 VDC setting (32 or 24 Volts usable).
Relocating the input B+ feedline to the 12V solder point/hole would configure the sounder for 11-20VDC use.
