Yes, it is the Problem I Can't Solve.
Lately my packing gland has been acting up which has me more worried than usual. I suspect that the local yard bent the shaft on the last haul-out. I was not there when they pulled her out, and didnt notice a problem till after taking delivery and operating for a week or two, so I can't prove it...
Moral of the story - always be there when your boat is hauled!
