I have a 1987 OMC 2.7 Sea Drive. I recently found one of the 12 volt leads from the power pack to the coil was disconnected. The end had corroded & fallen off. When I tried to repair it I noticed the copper wire inside the insulation was heavily corroded. My question is can I cut the coil leads near the power pack & install new wire to the coils. If so any particulars I may need to know about? Thanks for any help.
