  1. If you are in CRT water they are very likely to act. If you are in Peel water (the Bridgewater) they are near certain to act. The EA will act, once they notice. N

    Prop size

    Have you looked at a 4 blade prop? That will have a bit less pitch than a 3 blader but will still absorb the power. Cheaper than a new gearbox too, I expect. N
  3. The pressure switch in most pumps is the weakest point, IME followed by the shaft seal. It is worth fitting a separate pressure switch. Square D have a good rep and are adjustable. It will need a suitable tee fitting in the pressure pipe from the pump to taps. N
  4. I have been told that I should not have entered Newbold tunnel whilst a boat was in the tunnel coming toward me. N
  5. Once you have a suitable battery size do you have a suitable charging set up that is able, in a reasonable time, to put back all the electricity which has gone out? N
  6. Well they are well ventilated but also the easiest to vandalise as the access is so easy, both to the bowl and the pipework. I remember the one near Autherly junction, a couple of hundred metres up the Shroppie. It was more out of order than working, now it has gone. The one by the A45 road bridge in Braunston is similar, though that is mistreatment by users I think. N
  7. 100Ah LiFePO4 battery on Amazon for £379. Seems a very good price, but not quite too good to be true. Has essential emergency BMS stuff https://www.amazon.co.uk/gp/product/B08P4Z48RG/ref=pe_4022371_729066791_em_1p_0_lm Any one had any experience with Kepworth stuff? N
  8. Boatmens Mission at Walsall. Briefly a museum. Not sure what its current state is. N
  9. Whilst we can most easily measure Volts and Amps at any point, what we are really dealing with is Power, measured in Watts. Watts come from the sun, and some are caught by the panels and sent down the cables, very slightly less Watts go into the controller, slightly less Watts come out again, very slightly less Watts go into the batteries. Quite a lot less Watts are stored by the batteries. All the Watts lost before the batteries go to heat up the cables and the controller. The Watts lost in the battery go to making it gas and to warming it up. Now, since Watts are Amps x Volts, while charging, the Watts before the controller can be either higher voltage, lower Amps ( series panels) or lower voltage, higher Amps (parallel panels.) The Watts after the controller are at battery charging voltage, and the Amps are as necessary to make up the right number of Watts. N
  10. Blisworth, cos it is wide and deep and you can get the boat settled nicely on it's own wave system so it becomes incredibly easy to steer. You also get a free roof rinse part way through. Gosty Hill cos it means you are nearly at Hawne Basin, and a very friendly group of boaters. Newbold. The lights are an amazing tribute to the stunning incompetence of BW and local officialdom. Are any still working? N
  11. Dual fuel engines are common in big ships, but they just use gas and diesel. A tiny quantity of diesel (tiny compared with the quantity that would be needed to produce the full engine output) is injected and burns, acting as the ignition source for a large volume of weak gas/air mix. The gas is usually CNG, revaporised LPG or LNG boil-off in gas carriers. The benefit for the extra complexity is lowered sulphur emissions and lowered consumption of low-sulphur fuel. The device described by the OP will cost power, not provide extra, and you would need to redesign the combustion space to get any emissions benefit. In which case a low-emission pure diesel can probably do a better job. N
  12. We have a tall Indesit fridge jobby at home. That too is prone to being noisy, but the makers helpfully included a booklet describing its various burps, farts and gurgles! N
  13. To add to the possibilities 1/4 BSP is 0.518 in ( just over 1/2 in) or 13.16 mm OD. N
  14. No pic for me. What is the outside diameter of the thread? 3/8 BSP is OD 0.656 in ( a bit bigger than 5/8 in) or 16.62 mm and is 19 tpi 1/2 BSP is 0.825 in ( 7/8 in) 20.995 mm and is 14 tpi. If you don't have a caliper, a decent adjustable spanner and a tape measure can be used as a substitute. If in doubt, order a 3/4 BSP socket in the new tank and buy brass threaded bushes 3/4 outside by 1/2 inside and 3/4 outside by 3/8 inside. One will fit. Your local plumbers merchant or Plumbase should have these. N
  15. Heldite, or the Tru Blu stuff Toolstation sell are best for diesel. Hylomar or Wellseal work if you are in straits. PTFE tape, of the water or gas type, are not suitable for diesel, though they do work for a while. N
