  1. More expensive but the whale supersub pumps look really good. I just bought two for the stern tube drip bilges (twin engine boat). The automatic ones, which have an internal sensor of some sort and have a joker valve in the outlet. The boat hardly takes in any water but stern tube drips do accumulate and overflow into the engine drip trays so a couple of little supersubs seems sensible. Stuck down with magnets. If I had a boat which regularly took on water I would install an auto bilge pump in addition to one running on a timer mounted a bit higher which operates rega
  2. Obviously I know nothing about narrow boats but I have never seen a stern like this on a modern boat. Usually you use the end of an old iron boat as the bows. Its quite good in a way but the London white interior and exceptional state of the art thing makes me suspect it is a sinker. And one would want to see what they have done about the swim. It could end up being a very unusual early pleasure boat using the front of a horse drawn boat, with most of the thing replated with treadplate, as the stern. Or something. De
  3. Nanni diosol is of course Nannidiesel. Probably a Kubota V1505. Parts should be readily available. https://www.peachment.co.uk/ Are a UK distributor for these units. Quite likely to be this item and probably the same one as midland swindlers are selling. https://www.asap-supplies.com/products/mann-w-67-1-spin-on-oil-filter-for-kubota-nanni-beta-yanmar-102067
  4. Yes the Midtronics units mentioned by KeithM are based partly on a Motorola patent as I mentioned before. In fact they still seem to add text to this effect in the manual. Among other patents "This product may utilize technology exclusively licensed to Midtronics, Inc. by Johnson Controls, Inc. and/or Motorola, Inc. (That's for the Midtronics MDX640 which is indeed not a £35 product). The old one I have was about £20 on eBay I collected it from a man with an Irish accent who had a house in Slough with a nice large motorhome beside it and a loc
  5. Did @gibbo ever get into this ? He seemed to know all there was to know about lead acid batteries and state of charge. Very smart.
  6. My old Saab 9000 had a very nice feature which was a voltage display on the dashboard which showed the minimum voltage of the battery during starting. It logged the minimum and displayed if for a short time. Built in discharge tester. Clever really. The later Saab 95 doesn't have this feature.
  7. I've got one of the original conductance testers which Midtronics units are based on. It's a Motorola moving needle unit (Motorola patent). It is pretty good for checking what the battery is actually like in real life. I actually used it as part of the details for a warranty claim on Rolls batteries. As well as a refractometer for the acid, obviously. They do turn up on eBay now and again. Rather bulky though. I think Hoppecke badged them too. Old school gear but very effective and does not need it's own batteries. It's one of these.
  8. Another search term "dwusuwowy" is polish for "two stroke" This one comes up with a sailforum.pl page referencing puck 2 stroke diesels. "dwusuwowy diesel puck"
  9. Did you search Google for "silnik puck"? Silnik is Polish for "Engine". Quite a few results including a RetroTraktor forum which might be interesting.
  10. Have you considered looking it up in the Post Office archives?
  11. There was one of those but smaller on the Paddington arm last year. It was attached to one of the more normal looking oil rig lifeboats. I thought the regular testing was to do with age of vessel and structural integrity and explained why they come up for sale. Because they have somehow failed the test. Or maybe they just have a fixed life.
  12. Yes that's what I meant by "secured correctly" but in that location and with that much change of level as someone mentioned earlier a 2ft deep flat bottomed boat may be in danger of ending up on the bank then falling over when the level drops. There is also the risk of the side decks of a canal boat being wedged under the wooden trim above the piling in this particular instance if the boat is not properly fendered. You actually need quite large ball type fenders or rod buoys to do that in this location. ETA as it is not on the River itself but in a lock cut there is n
  13. Being a very deep lock the level changes enormously immediately below it as this graph from the recent flooding shows. Looks like 2m+ of variation which is too much to deal with if the boat is not securely correctly and there are no riser poles .. It's the LAST place you would want to leave a boat. Probably one of the worst places on the entire river. Above the lock would have been infinitely better.
  14. I suppose you could argue that anyone using a boat should have at least a basic understanding of how the system works and learn how to recognise the difference between a lock approach/waiting area and a visitor mooring site. The latter, if it is a proper site with rings or bollards, will generally be signed as being a mooring and the maximum stay allowed. A length of made up river bank with bollards on it and very close to a lock is probably going to be a lock layby/waiting area. It seems obvious. Probably isn't though and the fact there is a
