  1. Hi everyone. Just to update this thread. I found an industrial JS3 and bought that thinking it ideal because it would supply a flywheel for my friends boat and an engines worth of spares for the JS in Prince. However. Having just got both flywheels off I can see that the reverse sides are quite different. I was expecting the JS one to have no provision for the hand start mechanism and suspected I'd have to fabricate an adaptor to take the JP sprocket etc. On further investigation though, not only is the rear hub substantially smaller diameter but crucially
  2. Yes, I've done that to the manifold but the air filter itself is sealed and I can see the same gunk in there but can't clean it out. I could cut it open and weld back together but I'd rather not. OK that makes sense, I've seen some exhausts with the same thread but didn't want to get the wrong one. I'll look into oil Bath filters. Thanks!
  3. Yes, but in this case there is quite a bit of gunky particle-y stuff in there and I'm pretty certain it was a bit of that which held the valve open so I'm not going to put it back on.. Slightly worried about sucking a leaf/ small child or my cat up that pipe though..
  4. Yes that is the type! But for the life of me I can't find them for sale online. If I knew the name to search for... Can't even find them on mps site and couldn't get through on the phone.
  5. Sorry to ask another question of you all, folks! This one is a really boring one too.. Does anyone know the name of the type of air filter normally fitted to JP engines? Prince's is a sealed canister type and has very much passed its prime. I had a stuck valve (carbon deposit on the inlet valve) the other day so have stripped and decoked all the heads and manifolds as well as lapping the valves but I cannot find the air filter online anywhere because, in this modern world, its all about knowing your search terminology If someone could please tell me the ty
  6. Are all Jp engines the same roataion? I know that a friend was surprised that mine used a right hand prop, believing that all, listers used LH ones. Would it be possible to mount the starter on the other side of the engine? Ie not beside the Injector pump but the other side. Oh I guess the water pump is in the way.. Mine has the seawater pump which is in another place entirely. I had one of these on a 4 cylinder Ford lifeboat engine, it always shocked me how easily it spun it over.. Compressed springs and contained gas always scare me a little.
  7. Indeed, I was just starting to look for any Jp3 engines online (from generators etc) but might have to think on the direction and mounting of the starter some more if it may be of the wrong rotation.
  8. Thanks everyone, I might actually follow that, suggestion and look for a Jp3 complete for spares, in which case I would have plenty of bits for Prince's JS as well as a flywheel and starter for my friend. Anyone got one kicking around? I've just had a look at the JS and the starter is bolted to the engine bearer via a cast plate with the straps in o e piece. If I have a hard time finding a donor engine I think I could make up something similar. That one at redshaws is too pricey for me. I'll have a search now, but if anyone knows of an engine (ideal
  9. Hello folks. I have a friend who is looking at a boat with a hand start only Jp2 in it. She would need it converting to electric start so I'm looking out for a Jp flywheel with ring gear attached plus a suitable starter motor. Does anyone on here have one for sale? Or any of the bits that would assist with the conversion (I'm assuming that I will have to fabricate a mount for the starter but if there are fittings available I would mu h rather buy one that was made for the purpose) All the best, s
  10. Thanks, that is my original post from when I bought kerbau in 2014, Alan's site I have already seen.
  11. Yes, I'm certain that the Harris brothers did the conversion but from an old Hull, I'm also certain that it is not a Bantock because they have a curved stem Post and this one is straight below the top curve. What really puzzles me is the plating, I have seen Calder barges (like June) made with lots of tiny plates but never a joey. Plus the way the plates overlap looks counter intuitive at the gunnel and the footings which makes me think a long strip of iron from some other purpose had the gunnels and footings riveted on to make the hull. Either way I'd be interested to hear
  12. Hello again folks. Happy Christmas to you all! Im writing this time with an enquiry for a friend, she bought a previous boat, Kerbau - a shortened bcn joey, from me some years ago and loves the boat dearly. However she does need a longer boat and has been looking for a suitable project BCN boat to replace Kerbau but to no avail so far. So, while that search continues, she is looking into the logistics of lengthening Kerbau with sympathy to the hull, the issue being that she is not built like most Bantocks or similar (of which there will be plenty of useable sides around t
  13. Great, I'll have a look at that site, thanks! Yes! It does have an extreme pitch (and pronounced prop walk to boot), a 28x20 is required I believe. True, as soon as he is out of the water I'll be swapping the prop. I do believe also that the town class boats swim allows more water to the propeller easily due to its steeper vee shape rather than the rounded barrel shaped swim on Prince. I will investigate the pump and let you all know when the prop is changed.
  14. It's only that I steer a few of the coal boats which have much smaller engines than the JS and they can really really throw some water out the back when wound on a bit which Prince rarely does. Prince does have a 24" prop which is a bit small really but still.. I am aware that I may be looking too hard at something which isn't a problem, it's pretty shallow up here and he is pretty deep as well as having a very different shaped swim than other GU motors, all of which could affect it. Given that he runs smoothly with almost no smoke and good oil pressure I'm inclined to
