  1. Most domestic calorifiers are of the indirect vented type, the cold water feed is from a seperate stoarage tank, and they have a vent pipe back to the header tank, these are typically rated at 10 mt head of water which equates to 1Bar or 15 PSI. It is possible to use a vented type in a marine situation, but the system need to work at the appropriate pressure. Steven
  2. I was answering your question about LW's
  3. LW'S were available in handed pairs if required so it all depends on where it originated from. Normal roation is clockwise when viewed from the non flywheel end
  4. My family has two boats with 3LW's and 2:1 gearboxes one is is 50 ft the other 58ft both are fitted with the same prop as in the picture. They are 23" X 23" and as can be seen are are of a large blade area. Normal cruising revs are 500, max revs are 1000, Almost never use anything over 750rpm. Boat stops within its own lengh in deep water. Although you cannot fit 23" dia the nearer you can get will give you a good result. Steven
  5. A couple of pages about the Pelapone from British Diesel Engine Catalouge published in 1950
  6. Jasmine at the Stourbridge Rally Photo By Alan T Smith
  7. The knurled silver knob doesnt look like an original part, that is where the breather is usually located. The dipstick should be attached to the square headed plug as shown in photograph 1, it is part of the plug and can only be found when the plug is removed, the drain plug is not visible on either of your photographs it is in the centre underneath nearest the flywheel. The plug shown with the blue arrow is on the hydraulic pressure circuit and is normally used with a trolling valve. The large Hex plug on the side in pic 2 may have a filter behind it on the suction pipe inlet, dont know when they started to fit them but my 750 has one
  8. The dipstick is part of the filler plug, there is a drain plug at the lowest point of the gearbox, not easy to see
  9. In 2017 it came to a rally that i organised so I can confirm that at that date it was called Gibson Beans. Mark who was / is the owner did explain the name but I have long since forgotten Steve
  10. He definatly built more than one, my brother has one built by him in the early eighties, it was named Baltic when purchased and was 45ft long, now stretched and recabined.
  11. Was it Bailey Manion? who I remember having a boat called Ratty Steve
  12. Ladybank is now a nearly new boat having been completey renewed between the engine room bulkhead and the bow by Ian Kemp during 2018/19
  13. The MCB's are not speced as suitable for DC supply https://www.hager-me.com/products/energy-distribution/protection-devices/mcbs/mcbs-onekonekt-mcn/mcn125/47712.htm
  14. The spec sheet for the relays is here https://www.willow.co.uk/RG25.pdf 12v DC relay has a coil restance of 85ohms so current is 0.141 amp
  15. Lock 1W on the huddersfield and the end of navigation at that time, the photographs were probably taken at the time of one of the tameside festivals, the second boat in the pictures is Pensax and is the same one as in post 8 by captain birdseye
