Hi @Arthur Marshall, I was wondering how your coupling attaches to the prop shaft? Just interested for when I come to fitting mine. (Sorry not for sale ? ) Pic Thanks Haven't got a clue. I'll take some photos next time I go down. I seem to recall that the propshaft is tapered to fit, which is one reason I couldn't replace it without replacing the shaft too. That does look like mine though - any idea what it actually is, and out of interest, is it a Lister? And if you ever find another one... 1 Link to comment Share on other sites More sharing options...

I should imagine that that is tapered too with a big nut on the shaft end inside. The boss is too short to be anything else really. 1 Link to comment Share on other sites More sharing options...
Bee Posted April 2, 2019 Report Share Posted April 2, 2019 Has a bit of a home made look about it. The welding on that boss looks a bit like something I'd do (But a bit better) 1 Link to comment Share on other sites More sharing options...

Approximately what diameter and thickness is your coupling, Arthur? Richard Link to comment Share on other sites More sharing options...

The bit I was looking for was the rubber bit, which we had to hack chunks out of in order to undo the nuts and get the gearbox out. How does that compare?

Traveller Posted April 9, 2019 Author Report Share Posted April 9, 2019 (edited) I'll have to measure it when I get back to the boat which won't be for a few days so will report back. The boat is a mid 80s Peter Nicholls and I believe this was quite a standard arrangement for his builds - BMC1.5 and a TMP gearbox. Thank you for the greenie, Richard. Thanks Brian. I believe the term is: normal service has been resumed ? Edited April 9, 2019 by Traveller big thumbs! 1 Link to comment Share on other sites More sharing options...

ETA I would be interested if Richard has got something similar to mine, but only for future reference as I'd like to know more about it - I'm not planning on replacing the thing unless it falls to bits, which everyone who has seen it thinks very unlikely. And if it did, I would probably use something moderner. Edited April 9, 2019 by Arthur Marshall Link to comment Share on other sites More sharing options...
Traveller Posted April 9, 2019 Author Report Share Posted April 9, 2019 Thanks Arthur. My pet engineer is of much the same view - it will last ages if not hammered. Like you, I am trying to be prepared. Link to comment Share on other sites More sharing options...

Like you, I am trying to be prepared. I had to take mine to bits to get the gearbox out. Because the thing was so old, the nuts just turned the bolts and the only way to get a spanner on the other end was to saw chunks out of the rubber to get at them. Then the gearbox broke again and we had to do it all again, making it worse. I took it to a local guy who repairs rolling belts and does rubber annealing and he filled up the holes the first time. Second time was a nightmare - gearbox repair was fine but the engineer didn't put all the bolts back so out it came again to be done properly. This time I think I just plugged the holes with heavy duty Sikaflex or something like, but the yard reckoned it was about five times as solid as a modern coupling , even with the holes. It looks a bit of a mess, so it's got a couple of yards of gaffer tape round it to tidy it up. Been fine for two years now and shows no sign of breaking down, unlike my knees, back and other bits of me. I suspect it'll outlast my boating life, and probably my actual one... 1 Link to comment Share on other sites More sharing options...
bizzard Posted April 9, 2019 Report Share Posted April 9, 2019 They can be reinforced by binding several coils of wire around the rubber and twisting up tightly. Or two big Jubilee clips with their drive screws opposite to maintain balance. Link to comment Share on other sites More sharing options...
