  1. The oil pump can simply be removed with the gearbox in situ. When replacing just be sure to put it back on the same way. There are no gaskets, but rubber o rings to seal. These will be re usable although you should check the condition. They can be held in place on the pump with a little grease. Also be careful not to lose any of the shims from the end of the shaft.
  2. The owner of that business sold the business a few years ago when he retired. The boats and business were sold to Saul Junction Marina. The boats were repainted and carried the Saul Junction Marina logo. The operation carried on as normal. Whether they are still in operation I couldn't say as I have been away from the area for at least 3 years.
  3. There have been a number of hire companies on the G&S. Many years ago there was Glevum boats that ran for a good number of years quite successfully. When the owner sold up the boats moved to the Black Shed at Slimbridge who unfortunately let the boats go downhill and in the end the business just fizzled out. In later years another company started up. That was Gloucester Narrowboats. Again that ran successfully for a number of years until the owner retired. The boats were sold to Saul Junction Marina who were operating them as hire boats. All of these businesses were using small boats doing day hire. Both Glevum and Gloucester Narrowboats also operated a larger boat which was used for 3-4 day hire. Both of these companies restricted use to the G&S only. The main reasons for that were not wanting to let inexperienced hirers through Gloucester lock onto the Severn. Also if there is a breakdown or any other problems on the Severn it can be a nightmare getting to the boat. As I say both of these businesses were quite successful in what they did.
  4. The Elements for an ST engine, assuming you have the original casing are either 366-06227 which is a paper element, or 366-06741 which is a foam element used on marine engines. The foam element was more a thing on sea going boats as the wet would not do much for the paper element. The 366-07188 which has been suggested, will not fit. That is the element for the Alpha housing and is thicker than the ST elements.
  5. I think you will find that is the limit of navigation (end of CRT waters) not the source.
  6. As you say they sit on a copper washer. There is also a heat shield below the injector nozzle. Both these should be replaced when changing an injector.
  7. Well spotted. That'll teach me not to post to fast, and without checking the spellchecker.
  8. If it were me I think I would helicopter the coupling threads and then fit studs using a high strength locktite.
  9. Ther are probably different solenoids available. Energise to stop for marine engines, and energise to run for industrial applications.
  10. It was built with the Ailsa Craig engine.
  11. That is quite correct. I know the guy who built it but won't put his name up here. It was built using all the Northwich Trader templates, but if I remember correctly Phil insisted on a few small changes so it didn't look identical.
  12. The thermostat will just be the normal type. As I mentioned earlier a lot of these would have left the factory with a 50 degree stat. So worth checking out. It can be replaced with a 74 degree stat assuming it is keel cooled.
  13. As said the spring and ball acts as a bypass. This is needed because the jabsco pump is a positive displacement pump so you don't want to stop the water flow and also you need to keep a water flow to the water cooled exhaust. The way it should work is that the barrels and heads and water manifold hold the water until it reaches the thermostat temperature. The thermostat then opens and allows the hot water to mix with the water flowing through the bypass and out of the engine. So when the engine is running the water in the water manifold should reach thermostat temperature. As these engines were primarily made as raw water cooled engines running in salt water they would have been fitted with a 50°C thermostat to ensure the salt wasn't boiled out of the water. Obviously running as a keel cooled you can safely use a higher temperature thermostat.
  14. Most of the marine engines did not use the self bleed system. I've come across it a few times on industrial engines. I think you would have to order as an extra when placing the engine order.
  15. Have you removed the fuel pump housing door and bled your injection pumps.
