You should be able to find it hereDayDreamer41.............nice diagram with lots of detail......wished my Hunter 46 manual had the same!!
Thanks terry most helpfulThe most forward starboard cabinet in the main cabin has a small panel on the forward side that can be removed. That is where you will find the solenoid for the siphon break.
Great vidio most helpful !!I am going to make a guess it is in the head or vanity behind a panel attached with screws as that is where I found mine on my Hunter 386 when I replaced it. Once you find it it is a simple plug n play. I think this is the part.
