	Hi Graeme To recruit Norwegian (possibly also Scandinavian) crew you can try the site Sorgenfri.com (http://www.sorgenfri.com/forum/categories/baat-soeker-mannskap/listForCategory). This is a Norwegian site, mainly in the Norwegian language. However, you can post an ad in English under the Forum category “Båt søker mannskap” (Boat seeking crew) and hope for answer. Good luck and good winds. Best regards from Bjarne, impatiently waiting for my new 505 next April.

	Only a month and a half have gone by but it seems like 3 months of activity. Columbia was Great. We went to local activities, learnt to differentiate coffee into the good, bad and ugly. Made lots of contacts and some good friends, having a 6 yr old on board opens lots of doors. Walking the Plank? Still happens in Club Nautica... Club Nautica marina was what you could describe as "interesting" in the same way women use that wonderful expression "fine". Total lack of customer service, close promptly at 5, closed all day Saturdays and Sundays... But the other sailors there made up for it and there was always the regular sport of watching those out at anchor drag past you when the winds suddenly shot up to 35 knots and the harbour became somewhat "untidy". We are in San Blas now and I cannot tell you just how different this part of the world is from that around it. It isn't just the beautiful anchorages, it is the friendliness of the local people once we made the attempt to go past the tourist superficiality and go under the surface. We had one unfortunate setback on the way from Cartagena to San Blas. WE hit something or wrapped something around our prop at 3 in the morning, lots of vibration from the sail drive and prop, engine couldn't go past 2000 rpm and in the middle of a squall! When I was able to dive on the prop the next morning I couldn't see anything. BUT - when I next inspected the sail drive half the oil was gone and if I try to go past 1500 rpm a noticeable vibration becomes evident. At the moment we are losing about half a litre of oil a day. We have a Brunton 3 blade folding prop. Can anyone suggest what may have happened, I can see I will have to haul out and replace the seals (again, just done in Trinidad) Is it possible for a prop to go out of balance even if there has been no physical loss of materiel, ie chunks out of the blade? I have to treat the cause of the problem of the new seals will go again. All advice would be welcome on this one. Fresh crab, dressed, all for $2 The library at Isla Carti is seeking a librarian...

	Hi are you saying oil is leaking out and water is not getting in, if so the propeller seals are not at fault. Have you got oil leaking between the sail drive and engine, is it possible oil is being forced out by pressure within the saildrive . Have you dived and inspected the the operation of the folding prop Just some ideas Dave

	Hi, I bet the prop shaft is bent !

	Thanks Panos. The sail drive shaft is only a stubby thing, do you think that would be possible? If so, will be great fun sorting out in Panama, guess I can buy bits in Uk and fit when I haul out. Have to find someone with experience here.

	Of course is possible. If you hit something big (a log or a palette for example) you can loose or bend a blade or if the propeller is much stronger than the shaft you can have a bent shaft. This explains the loss of oil, the vibrations and the increased friction. I'm betting a case of beers! Another even worse scenario is a deformed sail drive case, but this is a very remote possibility. It could be deformed or broken pinion gear but in this case you wouldn't loose oil and a loud noise coming from the not matching gears. Edited by panos - 25 September 2014 at 18:09

	Hi Guy's, Giving our experience with Yanmar SD50, I wouldn't bet so quickly! 1° Oil leek: the external water pressure against the shaft seals would avoid any leeks from inside to outside. When the seals are worn the oil level in the saildrive tend to rise, as you get water inside! 2° Oil "disappearing": most of the time it comes from the main seal between the engine and the gear box. 3° From what I know, the propeller shaft is much stronger than the folding blades. 4° In case of a bent shaft, you could not rise the engine revs so high (1500rpm). The noise would be horrific much before. From our experience, we broke two teethes of the propeller shaft pinion, and we couldn't go over 1000rpm. 5° I suggest that you check existing oil underneath the engine (remember that the oil capacity of the saildrive is around 2,2liters, which means that it would have gone dry in less than 3 days...with a lot of oil signs around the boat....) 5° Personally, I suspect a bent blade. 7° All in all, you will have to haul the boat out to check it, and open the bottom box to check the bearings. 8° In case of change of bearings, keep in mind that the shims should be adjusted with cautious. Not doing that in Tahiti, lead to a saildrive breakdown and replacement: 5000€ PS: If I am wrong Panos is welcomed on board for drink and sailing...in New Zealand Alain

	Thanks Panos. Having looked at the price for a new prop shaft (£700) I am wondering if it would be possible to have it straightened out? If we were back in Guyana someone with a micrometer and a press would probably have a go, in Panama not so sure. What do you think?

	Ok, I don't want to start an argument since Alain certenly has a point with oil vs water pressure. Although the theory that the upper seal is responsible doesn't explain the vibrations and increased resistance and low RPM. My bet still holds because my theory is that the slightly bent shaft acts as a pump and pushes oil out of the leg, only when turning though. Whatever the problem the leg has to be disassembled. I dought if it is possible to straighten a hardened shaft but if it is possible only a third world mechanic has the talent to do so. Technologically advanced mashine shops wouldn't touch it with a ten foot pole. Replacement would be much much cheaper. My two cents only! Edited by panos - 25 September 2014 at 21:08
