Re: E32 Leak around stern tube for prop shaft
Why is it leaking? Caused by ...?
Not just curious, depending on reason then it may more or less important to dig deep.
If it is "Just a leak" and your only ambition is to tighten, then it may be possible to to without removing the shaft. If you want more, and really be sure to make a good job, then I recommend to remove everything that just might be in your way.
Done similar job, had to remove shaft otherwize I wouldn't have sufficient access. Job in itself is rather strightforward. Important to see to that no water stays "inside".
