  1. Any news Doc? This saga is surely solved one way or another?
  2. Quite a few have done this (its on my list too...) a bit of organising with the barge across manapouri and then over the pass . by all accounts Feb/ early March is the time most likely to give moderately settled weather. "Sailing Taranto" on youtube gives a bit of info on the area, and encouragement to go as well. The boaties guide to fiordland i understand will give a mine of info. I'd be keen to hear first hand from people that have done this trip as well
  3. The bracket is mounted quite low on the transom so you may get by with another short shaft if good one was found at the right price. our 20' has a yamaha 8 thats been to the moon and it's still easy starting and reliable, plus the two strokes are a fair bit lighter than the four strokes...
  4. I see a bit of work cutting the bend sections to match the required shape , a little bit of lathe work and welding plus material cost. Quality work done quickly - if he charged much less he could well go out of business .
  5. It's impressive that after 47 years or so the working parts are likely still good and it's only corrosion that's getting the better of it...I use a small Foundry for one-offs at reasonable prices in my engineering work . A possibility is to replace the casing half (or halves) and save on doing any other mods/retrofitting. Perhaps send me a pm if that interests you.
  6. Any chance of some photos of the problem pieces? Where are you located? It may be perfectly viable to restore.
  7. Our off the grid diesel generator at 1500rpm uses around 0.9 litres/hr unloaded and about an extra 0.3 l/hr for every KW we draw of it - i'd expect a similar thing to happen to your consumption .no free lunches sadly applies to the humble volvo or in our case an LD20 also.
  8. These foiling beasts sure are a spectacle but i'd far prefer to see racing like Fremantle again ...
  9. Any news Doc? we can't leave eight pages of mystery...
  10. Quite neat how business/service used to be... I'm not sure if its still the same but in the early 80's i went into E Hayes in invercargill with a shopping list as far fetched as you could imagine, and part way through it we got to the 35 thou annealed copper sheet to which the shopkeeper frowned and said follow me and below ground level was an aladdins cave of hardware and amongst it was every different thickness of annealed copper you could ever need.
  11. I see a third crew member has been found and alive - hopefully more to come but ... I see these big ships sink fairly often ( every week ?) https://www.fleetmon.com/maritime-news/2019/26281/ships-losses-2018-how-many-ships-were-lost/#:~:text=The report revealed that the,) - global
  12. Grim news from the survivor - engine failure followed by capsizing ... https://in.reuters.com/article/us-japan-newzealand-ship-idINKBN25T3EH?fbclid=IwAR1F9C3c7HUq_E8bo5SpG0NRA7uC-_iIAGWzNwM0lPoECcHuuo6RghsL2xY
  13. The clank happens 15 times in a whisker over 13 seconds - i did some calculations based on idle speed of 800rpm . that gave a clank near to exactly every 12 turns of the crank. we need to know what that engines idle speed is set at to be sure . Doc? . heres a good question though ... what would make an engine try to twist on its mounts the same direction as its rotation and also make a clank sound? we need to have a barbeque in Brittany to find out...
  14. There are ways the engine could cause this problem - and i certainly don't know many of them but one possibility is the case hardening on one of the camshaft's injector lobes failing and contaminating the roller and pin that actuate the actual injector - causing it to "run over a lump" (firing its cylinder early ) which would happen at a rate according to their relative diameters . Certainly left field but occasionally even an airliner falls out of the sky with some obscure left field fault.
  15. The sail drive is 2.3 : 1 or thereabouts so that becomes less likely. a warm engine will react to (ignite) a stray amount of fuel much more readily than a cold engine. Pity you aren't in NZ we could have a Crew barbeque with a sweepstake while we sort it...
  16. the engine jumps clockwise with each clank - the inertia of the crank is clockwise, if something like the injector was faulty and fired a cylinder way too early then it would exactly do exactly as we are seeing and hearing. I have seen the same thing on a petrol engine when the electronic ignition unit was being overwhelmed by a failing voltage regulator. I could easily be wrong and i've never had a volvo injector apart but it is a possibilty...
  17. Hmmm it's very regular... and by the way the engine shudders on its mounts its not pretty. i suspect there may be issues with the injector pump. let us know what the tech finds - good luck!

    2:1 halyard hardware

    So i've done a couple of sketches and they show in a 1:1 setup with 50 kg (technically should be called 500 newtons) of force holding the sail in position there is 50 kg of "pull" in the halyard going from the sail going up to the sheave and of course the same 50kg pulling down inside the mast - so the sheave is compressing the mast by 100 kg. With a 2:1 set up there is only 25kg of load on the halyard so 25 kg where it terminates above the sheave plus the 25kg going from the sail up to the sheave as well as the 25kg coming down inside the mast giving a total of 75kg now... I'm pretty su
  20. Ideally if the shaft and prop bore could be measured then a good plan might be formed, or is the looseness only on the key? . Regardless the grubscrews if they must be kept on should seat in shallow dimples and be loctited (262 or 263)
  21. as a self employed contractor you need to be payed around 30 to 35% more than a wage earner to end up the same at the end of the year (holidays,the odd sick day stats acc levies cost of accountancy etc). There will be a bit of a variation if the wage earner is regularly on penal rates.I have a spreadsheet that shows the costs and comparisons of being self employed (albeit 10 years old) that i can pm to you if you like wheels.There is a lot of bigger picture stuff involved too like whether you are looking at a short or long term prospect and even how much it would cost to get to work, and if yo
  22. For what its worth we occasionally have a similar thing happen in our off the grid set up of 15 years . typically we run two sets of 4 6v lead acid 220ah batteries in series (24v system) with the two sets paralleled. last summer 3 of the batteries (in one bank) started needing frequent top ups but the system seemed normal in everything else.early one morning before the sun came up i noticed amongst all the 6.2s and 6.3s i had a 5.8v on one battery (less than two years old) - changed it with a new one and all is well again... By any chance Fish have you compared the resting voltage of them? I
  23. For what its worth i had a frozen shoulder a few years ago following an injury and it barely responded to physio etc but after 18 months or so it slowly came right by itself so lets hope your one follows suit...I'm a real fan of starting the trailer sailer way as fish mentions and certainly you won't get bored with what we have in nz waters. Further to that anytime the pair of you are in the bay of plenty or thereabouts i would be real happy to take you out for a sail for a day or two - pm me if you are keen.

    Restarting the engine

    I think it would be fine to reinstate and "push the button". it certainly wouldn't hurt to turn the engine a few turns by hand to give the oil pump a head start but not essential. Definitely don't put any oil down the intake though as when that gets drawn into the cylinders the engine will very likely take off and possibly destroy itself. Years ago a friends father got a bulldozer into a very awkward position (more upside down than upright) and while he was standing next to it (still idling) pondering the predicament and how the boss would react it started to run on its own oil then took off a
  25. About this time last year my elderly sailing mate and i went ashore for a few days while some dodgy weather passed and during that time took a walk around the marina at nelson. As you do got chatting with an old salt who was tinkering with his boat and ended up spending a very enjoyable few hours listening to some pretty neat stories covering all sorts of things from logging and deer culling down the west coast through to sailing on the Nile overloaded with oranges - where else do you bump into people like that?
