Before I go further, we have had PYI units on two boats for over 25 years. I assume the first boat still has it working.

In you case, Dan, I don't know why you would have to pull the shaft?
You might have had to replace all of the "rubber" part because of unnatural wear?

Even then, they seem to doubling up on office (i.e. overhead markup and me mechanic labor) time.

They also should, if you asked have given an off-season discounted rate.
