hmmm...think about it! i have one #10 wire going to my rudder post, and then down to the bottom part of the rudder that moves, then to my stuffing box! Volvo wants their engines isolated, so they don`t pick up bad stuff if they halppen get into a so called 'hot harbor' my thru hulls are isolated too! ie, cooling water to the main engine/genset, i would check with your engine manufacterer...clyde
