as good a walking open wallet/blank cheque as you will get. Hmmm..... perhaps. Time will tell. And we have saved a lot of money by doing a lot of work ourselves.Have a little think about what has been about your fuel system Tony and I are in complete agreement it’s shite - @someboater has also pointed out its failings to you - no coincidence..... What is it we are supposed to do with it? I didn't build it / make it. Will look to make improvements, of course.Read what TonyDunkley typed pages back - he has covered everything that should be done to your fuel system already - you’d be better advised to spend your money there rather than on replacing perfectly serviceable sterngear.

Everything you've said in the above post - apart from the bit about putting Sikaflex round the outer bearing, . . which I don't even begin to understand - ! It was silicone sealant not sikaflex (sikaflex is a PU sealant not silicone). Putting a bit of silicone sealant on the threads of a stern tube when you screw it in is normal practice as I understand it. I have done this when replacing stern tubes but to be fair this was only as it was recommended by someone else. It does seem sensible. Obvious alternative being PolyTetraFluouroEthylene (from memory) tape. Foxy's post read to me as if there was some weird notion about smearing sealer round the outer bush where the tailshaft emerges from it !?! My own preference for sealing the threads of small sterntubes with screw-on outer bearings and stuffing boxes, or the bolt and flange jobs on commercials, has always been 'Boss White' (white lead) and oakum. I've nothing against more modern sealers, . . but there's still some of the real stuff left in the big tub that was 'liberated' from Manchester Dry Docks Co. after being left onboard MSCCo. tug 'Appleton' in 1964.

Everything you've said in the above post - apart from the bit about putting Sikaflex round the outer bearing, . . which I don't even begin to understand - does nothing other than underline what I said in my earlier post. You've got a perfectly serviceable tailshaft and stern bearing which neither leaks nor has needed the packing follower tightening any more than once since the stuffing box was re-packed over 4 years ago. The condition of your sterngear is testament not only to you having kept it sufficiently well lubricated, but more significantly, that your engine/sterngear alignment must be about as good as it can possibly be. Fitting or welding in a new sterntube and replacement outer bearing bush WILL inevitably disturb that alignment. If you want to reduce the chances of a breakdown of any sort, and to improve the overall reliability of your engine installation, you should be focusing your attention on that appalling fuel system and the equally dubious electrics. Age alone doesn't degrade or wear out sterngear, . . the fact that yours could be up to 34 years old is neither here nor there, . . it's clearly in A1 serviceable condition, and apart from continuing with the same routine maintenance that has worked so well since you bought the boat, . . it should be left well alone ! I’ll quote Tony and tag naughtyfox In the vain hope Ross takes notice of all that Tony has written - saves me repeating it... Foxy, we had a new prop shaft at 45 years old due to it running out of true - odds are high it had a good whack at some point in its life,(25 years of which were spent in hire on the broads) The sterngland packing and through hull shaftlog is still original (now 54 yers old) Take Tony’s advice - it’s free and will save you money and hassle - You must admit to yourself you are a marina owners dream, as good a walking open wallet/blank cheque as you will get. Have a little think about what has been about your fuel system Tony and I are in complete agreement it’s shite - @someboater has also pointed out its failings to you - no coincidence..... worth repeating ...... Sabina H had a new propshaft made due to discovering that the threaded end was chewed to hell and gone (glad I didn't know that when coming up the Northsea) the stern tube was installed in 1934 and is original and has seen out two engines at least ...... I do not anticipate changing it
