Shaft Corrosion ....................
....... this is most likely simple atmospheric corrosion (with a lot of salt water flying around) and is doubtful that it is electolytic as would be found underwater. The corrosion products on the shaft should be either red or orange. I have kept this under control by coating the shaft in this area with the heaviest tacky grease I can find. Not a permanent cure and needs periodic regreasing. Hope this helps. Regards, s/v Island Hunter
