You could also consider converting it back to a dripless. It is not that difficult. and you no longer have a constant drip of water coming in.
With 975 hours on my Bu, the Glide dripless seal started leaking. Only 35 bucks for a new seal, and about an hour of not very difficult work. Did not need to pull the shaft, just slide it back enough the take the coupling half off, slide old seal off, clean things up a but, slide new seal ring on. Bolt everything back up.
