Our new to us boat is 25yrs old and the rudders have presumably never been inspected. We do know that one had a bent shaft about 5 years ago and that the fix was "adequate".
There is no indication of damage, but one does drip rusty water
when held upside down, (yes, they have been removed) so we are assuming that there may be internal issues.
Does anyone know of how we should go about inspecting for internal damage without opening it up? Anyone know of a company in the New England
area that does this? Is this a part that may be nearing the end of life expectancy and we should just look to rebuild/replace?
