Looks to me like the rudder has moisture in it, the rudder post is oxidizing inside with the salts or whatever spilling out the top discoloring the fibreglass above it.Boat's still on the hard in insurance limbo as we figure out keel stuff, so I can worry about other things, like what's going on here with my rudder? The yard's gonna take a look at it but curious if this group has thoughts. Doesn't look GOOD at the very least.

I would start by drilling a small hole or two in the bottom of the rudder to see how much water drips out. You may need a new or rebuilt rudder as it would be weakened with internal corrosion. Just my thoughts...

Is that stainless steel in there or carbon steel?
So water penetrated at the top and traveled down, creating rust along the leading edge?
Thanks Ken, I'm about to do the same. That makes me feel better. Probably a good thing it's had 2 months to sit and dry out.BTDT
I drilled a 1/4 hole in my rudder and was shocked to find no water coming out. I do think I will install a bronze garboard plug with a pipe thread.
The hole I drilled in the bottom of my keel provided several gallons of water ; |
