i previously today sent a question about electric shock on my bowrail. after that i read a post reply about someone else getting a shock additional info about mine... not connected to shore power, beached on a sandbar,with no external power on only radio running (isolated that too). someone on post said you can't get shocked off 12 V, but i got a true 13 V and definite shock (I was standing in water up to waist) also tested on my boast lift in air w/ no shore power on ...13 V
