  1. As far as I'm aware they finished doing anything some time ago.
  2. At the time I was working as a self employed marine engineer and covering warranty work for Isuzu Marine as well as a few other major engine companies. Isuzu Marine have now become Engines Plus. Therefore all parts would have been supplied by them, and all genuine Isuzu parts. I don't really know what the parts availability is, but if stuck you could call Engines Plus and they may be able to advise.
  3. You are quite correct. The early Isuzu 55's did have an issue with head gaskets blowing. This was only an issue on the 55's and did not affect any of the other models. At the time the fix was to repair using a modified head gasket as supplied by Isuzu. I have done a number of these in the past and once fitted with a modified gasket there were no further problems. It was also recommended by Isuzu to replace the stretch head bolts at the same time.
  4. I've spent my whole life as a marine engineer. I certainly wouldn't claim to know it all. You can always learn something new, or a different way to go about things. If someone claims to know it all there probably best avoided.
  5. Should definitely slope uphill or have a Swan neck. Over the years I have had a number of boats with wrecked engines due to water down the exhaust. Just poor workmanship by the builder/engine installer.
  6. Definitely imperial as indicated with the shoulder at the top. Metric fittings have the shoulder at the bottom. On odd occasions some of the manufacturers nowadays don't seem to bother with this. The pipe in the photo is probably 5/16. Don't mix and match metric and imperial fittings, it's just a bodge and is asking for problems further down the line. I would say the problem you have is that the pipe coming from the tank has a tapered thread and your fitting has a parallel thread. Obviously been forced on and caused the split. As someone else has already mentioned you should really have a ball valve fitted in the return line.
  7. Here is the relevant page from the parts manual. You can see the o-ring under the coupling. The only thing I did get wrong is the fact that the coupling securing nut is castellated and held in place with a split pin. It must just be the smaller boxes that have a nylon.
  8. It sounds as if the oil is leaking along the output shaft and through the inside of the output coupling. Therefore not the output oil seal leaking. If I remember correcty when the output coupling is removed there is an o-ring on the shaft which stops the oil. Also when fitting the coupling it pays to put a little flange sealant on the flat washer that fits below the retaining nut. It may also pay to check that this coupling nut has not worked loose. I have come across this a number of times. It doesn't take much for an oil leak to start. If you take this apart it will pay to fit a replacement lock nut and ensure the correct torque setting.
  9. What sort of noise are you getting. Could it possibly be a singing prop.
  10. Can confirm that when I passed by at the end of last year it was still closed. But apparently sometime in the near future the pub at Haw Bridge will reopen.
  11. It looks like a steel bar welded to the hull for clipping cables, pipes etc. A few boatbuilders do it this way.
  12. May be worth checking all the electrical connections and the plugs and sockets on the loom. It could just be mild corrosion due to dampness and the time the boat has been standing.
  13. I may be stating something you are already aware of. The coupling in the photo is definitely metric. On the R&D coupling the line you can see machined around it indicates it is metric. An imperial coupling woud not have this.
  14. I have a friend who painted the decks of a fiberglass sea going fishing boat with chlorinated rubber paint. He absolutely swears by it. Says it is very hard wearing and keeps its colour well.
  15. If its anything like the workers that turn up on my local canal I bet they all have a personal CRT vehicle to get to site.

    Sorry but the two items on the lat post have ended up back to front. Read the second part first

    Here is a write up on bore glazing if it is any interest. It is talking about generating sets but that makes little difference as it is the low load factor that seems tocause the problem.
  18. There were probably many variations of the gearbox adaptor, depending on who built the engine.
  19. I'm sure someone must have a second hand one about. In fact I think I remember one being kicked around for years in RW Davis boatyard. May have been scrapped by now. Its the sort of thing you find in boatyard scrap or come in handy piles. But agree it will be one of those things that when you want one it will be impossible to find.
  20. Most probably been running out of alignment and putting excess strain on the casting. It will need removing. You could try to get it welded but if it were me I would try to get a replacement housing.
  21. Unless the lock keeper is out of the hut. Then you will just get the answerphone.
  22. You are right. But only the very early Canal Star engines used this type of spring dipstick. After a few years of production they were changed to a flat blade type.
  23. By the nature of the canal you can moor just about anywhere on the towpath side for 14 days. Saul Junction and Gloucester Docks are limited to 48 hours. If you need fuel the best spot is Joe Energy between Sandfield an Fretherne Bridges. They open between 9 am and 4pm weekdays only. If you stop anywhere near Frampton Green apparently the longest in the country the best pub is the 3 Horseshoes down at the bottom end. Patch is good for a stop and I think the Tudor arms does good pub food. At Purton you have the ships graveyard which is worth a look. And one of my favourite mooring spots is Sharpness where you can just look over the wall and watch the river. And you couldn't stop at Sharpness without a visit to the Dockers Club. These are only my personal thoughts but may be a starting point for you.
  24. All locks on the River Severn should be on VHF channel 74. I know a lot of the time the lock keepers can't be bothered to answer. In addition some of the bridges on the G&S use them, namely Llanthony, Junction and Purton. I suppose really communication and health and safety are not that high up the list with CRT.
  25. The levers on these gearboxes are quite stiff and that is how they should be when adjusted correctly. If they move in and out of gear easily the chances are the gearbox would slip. If you were to fit a Lister LH150 (hydraulic) gearbox it would also involve changing the adaptor plate, drive gear and adding the pump drive to the drive gear. The other option would be to fit something like a PRM gearbox but that would involve sorting out an adaptor and drive plate arrangements. You would be looking at one of the larger cast iron PRM boxes as I am guessing your engine is clockwise rotation and with these boxes you can turn the oil pump for either rotation of input. The other thing to consider when going away from the Lister gearbox is the drop of the reduction box, which is quite big. Most newer boxes will have a smaller drop therefore you would have to lower your engine to get it to line up.
