Done. Unit came apart easily and I found the two clutch
plates badly rusted. After some some with a wire brush and some WD-40 I put it back together and it seems to be working fine. I think these clutchs need to be disengaged and the boat
hand steered for a while to prevent this build-up from the looks of it.... Thrilled about the autopilot
, but just missed clearing out of customs
before it closed for the weekend. Guess I will stay put unit Monday...
Perhaps this help someone else now...
