I noticed a ring of substantial pitting on my rudder tube as well some time
back. I installed an inner stainless sleeve inside the weakened tube to
take the strain and hopefully avoid a failure. The inside tube is a close
fit, and is a heavy enough wall thickness to be of comparable strength. In
addition to the through-bolt at the head, I drilled holes for two more
through-bolts in the body of the rudder, then faired over the bolts.
Unfortunately it does add a bit of weight, but it's an alternative to
sourcing or building a new rudder.

Steve,
It is stainless. It is prone to corrosion. If you've got enough to look
(even "look") like a hole all the way through, my judgement would be a new
rudder sooner rather than later. Without an expensive exam there's no way
to know how far things have gone.
And you're right, they will fail when you need them most because that's
usually when they're being asked to steer in high winds and currents.
