Since my previous post Searay has arranged for the marina where the boat went for winter storage to replaced transom assemblies and outdrives. Thought this was great till I got the boat back. Had to finish alot of the loose ends myself. Was not a very good job. My question is that they said the galvanic isolator caused my problem so they replaced it. Now when I ohm the shafts between the drives I get 584 ohms. No other boat in the building has that. They all Ohm out at zero. My port drive to ground is 134 and my starboard drive is 450 ohms. My zincs are the same readings. Any ideas if this is correct?
