I had a chance today to look at the Tohatsu 9.8 outboard on the dinghy. It has not been turning. A bit of a bummer when you are trying to motor along and direction other than straight.
Flipped the motor over and was greeted by the sight of a thickly rusted tube. The tube that the motor is supposed to pivot on. Oops.
My best guess is the sacrificial zinc was all eaten up and this tube is the next best “sacrificial” metal.
