I've been going over the sphagettii wiring of my "customized" 28 with an 9.9 outboard. What I have found is the 8 gauge wire used to ground the mast and rigging is disconnected at the missing saildrive motor. This means there is no grounding to the water anymore. The yard that did this for the original owner could have at least bolted them all together. I guess I will try to terminate them to the rudder post some how. Thought this might help other odays with outboards.
