Rudder stock should not be 304 and 316 type stainless can suffer from crevice corrosion and is somewhat weak. A better choice would be Aquamet, Aqualoy or any of the other brand names in this class such as Nitronic 50. Nitronic 50 and it's counterparts are much less susceptible to crevice corrosion and are significantly stronger than 304 or 316 stainless. Unfortunately many builders have used 304 or 316 for rudder stock over the years and this may be one.
It's hard to say how much the repair will be and if the rest of the boat checks out it may still be worth it. If the rest of the boat needs work like rigging, decks, blisters, antique engine etc. etc. its a walk away..
