  1. I'm butting in here - knowing nothing about these engines but - they are much loved by seagoing types. Strange because they are direect sea water cooled without a heat exchanger. Consequently they get furred up.

     

    FWIW have a look on some of the YBW forums:-

    www.ybw.com/forums

     

    PBO reader to reader and Scuttlebutt sections returned several hits when I looked.

     

     

    The little BUKH engines tend to be direct cooled, but the 2G105 that I fitted certainly has a heat exchanger.

  2. Interesting story, thanks. So Tim has another three to track down now!

     

    No, I don't think so. I knew about Roger's, and the one which I fitted into the Thos Clayton 'gas' boat 'TAY', it's the one in King Arthur of which I was unaware. Roger may know of others?

  3. Ok, but this is 6mm plate so I think you'd need a big clamp to shift the plate into shape - in a boatyard yes, but probably not the sort of thing your average mobile welder carries.

     

    Also I'm not really concerned about the profile of the uxter plate, I just want to increase stiffness. A slightly convex shape on the underside is fine with me.

     

    No clamp needed, just a wedge. Standard kit.

    Main thing is that you are happy, I was simply trying to describe how it could be done if desired.

    How could clamps have been used to bring the plate and angle together? The boat is in the water at the moment, but I think you'd need huge clamps to shift it whether in or out the water. I've tried to push the plate up from underneath when the boat was out of the water but it doesn't move - not unless a wave rolls underneath and even then it's only flexing a bit. The bow in the uxter is just the shape it was built.

     

     

     

    You use a scrap bit of plate as a bridge across the angle, welded to the uxter plate either side, and then a steel wedge between bridge and angle. May have been a mixed blessing in your case, because the angle and plate will each deform to meet the other & you will still have a (reduced) hollowness to the plate which may collect water.

  5. Hi all, collected my, new to me, latest nb project today. 60' trad, built by coles morton, 1981.

    I have to say handles superbly!!

    She is fitted with a Bukh 2G105. I'm really pleased with this engine so far, cruised her for 12 hours yesterday and it just ran lovely. I'm an agricultural engineer by trade but know little or nothing about these engines. The internet turns up nothing?? From an engineering point of view, it seems very simple and very well engineered, does anybody know anything about these? How to date them? Reliability? Anything at all will be appreciated.

    Thanks in advance.

     

    There must be at least three of them in the country, in narrow boats - I thought there were only two!

     

    Basically a tractor engine, none the worse for that, see:-

    Here are a couple of clips of 302 tractors, but I think they both have the older engine.

  6. Will be keeping an eye on this post as we are doing the Leeds Liverpool (west to east) next week. We always look out for Wetherspoons. The ale is generally good. We spent a few hours in the one in Skipton a couple of years back when the weather was horrendous.

     

    There's one within the Leeds City station concourse, handy for the Basin. Absolutely heaving on a Saturday night, though.

  7. My one experience of fitting a new outboard impeller was not good. The supplied replacement impeller was a very tight fit on the shaft, and I hadn't really twigged that it was important for it to be able to 'float'. It was a good while ago now, so I can't remember the details, but the end result was some sort of seizure within the drive train after maybe 15 minutes' running. Nothing that couldn't be fixed by pulling it all apart again, and easing the fit of the impeller on the shaft, but a bl**dy nuisance at the time.

  8. is it a question of timing? It seems that the amount of fuel arriving at the filter from the spill will be less than that leaving to the fuel pump, where does the pressure come from?

     

    The secondary fuel filter is on the pressure side of the lift pump.

  9.  

    The particular injectors on that JP have feeler needles in the cap. If you put your finger on them, you can feel the injector 'creak' (!?!). They just rest on the top of the plunger and pass through a hole in the top cover. If you pressurise the spill return, it pushes the needles out

     

    Other engines are different, so it doesn't matter

    It will increase the risk of fuel leakage into the sump, and also reduce the effectiveness of the self-bleeding arrangements fitted to some air cooled Listers. Much better to return to the tank, or to a separate container if it's not self-bleeding.

  10. I think I read that dropping down into mancunia incurred less crap on the prop than heading up, but how true that be, I dunno.

     

    I think it's more a case that you can 'take your water with you' as you descend that stretch, which makes it easier if levels are low than would be going uphill.

     

    Tim

  11.  

    You shouldn't have a return to the tank, unless the tank is below the injectors and the return pipe is separate from the fuel feed

     

    Richard

     

    Glad to have my opinion confirmed ;)

     

    Tim

  12. Thank you all, I had spoken to you Martyn and you gave me great info and your time, just thought someone might have a similar fault before I take out the injectors and send them for repair. the return from the injectors to the fuel tank is clear, will let you know the outcome.

     

    Is the fuel tank below the engine?

    If not and if the leakoff is returned to the tank that could be contributing to your problem.

    The original design was for the leakoff to run by gravity into a little container. If there is positive pressure in the leakoff pipe, leakage is more likely, especially so if you have the original style of injector with the needle in the top.

     

    Tim

  13. If you haven't smelled gas, chances are that the leak is in the gas locker and so yes, very likely either the bottle connection (are you using propane? I've known bottles where the seating isn't very good and they are hard to seal) or the valve itself.

     

     

    Tim

     

    Edit - sorry, just re-read the OP, but I'd still suspect the bottle connection if on propane.

    How much does your boat draw?

    I don't know. About 3" off the bottom of the L&L ;-)

     

    I thought everybody knows the draught of their boat - or thinks they know, in the latter case they'll often think it's more than it really is rolleyes.gif

     

    3" off the bottom - where's the problem? ;)

     

    Tim

  15. The first part of your statement is most reassuring, the second less so. Some of the most revolting coffee I have ever tasted was "proper" coffee, whereas the rich-roast instant brews which I usually drink are consistently palatable.

     

    Revolting 'proper' coffee does certainly exist. We had a really good meal out some months ago, the experience was severely tainted by the disgusting coffee served at the end.

    That £250 equates to £5K in todays money.

     

    NB In D Blagroves books he just calls him "Morton" - never sure whether they did not get on terribly well or that's what he wanted to be known as.

     

    Maybe they both went to the sort of school where it was normal to address others by surname alone?

  17. Abso-blooming-lutely, and equally worrying that Dave should issue such a damning condemnation of the tastes of (probably) the majority of his forum colleagues.

     

    I have no experience of eating/drinking dog crap, but otherwise I'd be on his side.
