I do not know if my plan works, but it is the one I have for my M 15. I had a set of jumper cables made from the heaviest duty wire (biggest size) available. I cut the grip handles off and pealed the insulation back until I had only bare wire in the water and the insulation above that to keep from rubbing the hull. Then I placed a small bullnose clamp on the end that would attach to a shroud. (The 1/8" shroud was too small for the handle to grip it). The bullnose clamp flattened out the wire and made it large enough for the grip to bite it against the shroud. Now all I have to do it quickly clamp the end with the bullnose to the shroud on each side and pray that it works if needed. Well, really, pray that it isn't needed. Phil
