Re: Blown outboard prop shaft seal?
I had the prop shaft fail on my mercury 6hp last year. They tend to fail from non-use. The seal is rubber, so the heat can also definitely contribute to failure. I don't remember what the labor to replace the seal was, because I had several other problems fixed at the same time.
I thought at first I would replace it myself, but the whole prop shaft had to be removed to get the old seal out, which was more than I was willing to tackle. The labor to remove the old seal and seat the new seal was definitely more than the part, so if you are going to do the work or pay for it, I'd replace the seal, not just re-seat it.
