  1. Interesting! We've had to start mooring at the front to a mooring ring (when available) to the side and a chain forward of the bow because we're moving so much when moored. That could also be due to the number of hire boats going past at speed though 🙂
  2. Yeah - looking forward to it! Should use half as much fuel!! 🙂
  3. We're cruising up the Llangollen canal at the moment and have been almost coming to a standstill at some bridges such is the strength of the flow - we just thought that was normal for this time of year around here 😃 Thanks for the pics - we'll be in Llangollen soon to take a look!
  4. Sam Thanks 🙂 I think that the RCR engineer tried that but it wouldn't line up. We'll have to wait and see what Centa come back with. Martin
  5. Thanks Peter, Do you know where the plate came from? Thanks Martin
  6. Unless it's done on the gearbox side I don't think it'll be possible with this unless it's done on the gearbox side as the bolt holes are fixed on the centaflex
  7. RCR have said that's an option but also that it would invalidate the warranty on the new gearbox so they're trying to avoid doing it.
  8. Hi Engine: Yanmar 3YM30 (approx 2006) Boat: Narrowboat We've recently had our gearbox fail and it's being replaced by RCR who are doing an amazing job. The issue we have is that the new gearbox (which I think is a Yanmar KM2P-1 as that is the recommended on the Yanmar website*** for the 3YM30 but can't be sure as RCR have taken it away) has four bolts and the old gearbox had 8 bolts leading to a Centaflex-M. Old gearbox: Gearbox (8 bolts) > Centaflex flange (8 holes; 4 with captive nuts, 4 with holes for bolt passthrough) > Centaflex-M (4 screwholes) New gearbox: Gearbox (4 bolts) > doesn't line up with the four passthrough holes on the Centaflex flange OR the screwholes on the Centaflex-M RCR are contacting Centa-UK to see if they do an adaptor plate from the four bolts of the new gearbox and the 4 screwholes on the Centaflex-M but Centa-UK haven't been able to get answer yet. The questions are; - Has anyone out there known of a connector that will work between a Yanmar KM2P-1 (4 bolt) and a Centaflex-M - If there's not an adaptor does anyone know of an alternative to the Centaflex-M that will work with the Yanmar KM2P-1 gearbox? I've included a picture of the old gearbox setup as well as a close up of the existing centaflex flange front and rear. I'm not very technical in engineering terms so apologies if some of this doesn't make sense. Many thanks in advance Martin TL;DR New yanmar KM2P-1 gearbox doesn't fit into an existing Centaflex-M - RCR are doing a great job but I'm trying to understand the options from you wonderful people! *** https://www.yanmarmarine.com/Products/Light-Duty-Commercial-SOLAS-Engines/3YM30-400/
  9. It wasn't much over at all though - from what I understand it was more about the gearbox wearing out - the overfill was minimal so shouldn't have affected it. We've come a long way in a short time and before that the boat had been pootling up and down the Glos/Sharpness canal. It was just it's time.
  10. So... update time... The gearbox is officially dead 😞 We're waiting for a new one from RCR. Thanks for the nice message about the cleanliness of the engine bay - I'm trying to keep it clean but it's getting this time of year with muddy towpaths! The RCR engineer certainly liked the amount of space to work in though 🙂 Martin
  11. Yeah - that's what we learnt as well 🙂 She was named that when we moved onto her and the previous owners said they often had people calling the name out as they passed (they were living in and around London)
  12. Yup - that's us 🙂 We left the mooring last September and we are spending the year cruising around the country having a great time (when the engine isn't freaking us out). Martin
  13. Everyone, Thanks so much for the replies! I'm always amazed at how generous everyone is with their time, advice and information! I'm really sorry for a lack of speedy reply but we took the boat back today and after we were sorted we had to move up to a new mooring so I haven't been able to get on the computer. So... We took NB Jambo back to Oxley Marine on the Staffs & Worcs this morning and they have been absolutely amazing. We were hoping yesterday after they tightened the bolts on the Centaflex (which were very loose) that everything would be sorted but as we moved away to moor on the opposite side of the canal last night (it was getting dark) the problem reappeared and again we weren't getting any forward acceleration (during testing whilst moored up at their yard it had been absolutely fine). So as we crept over the width of the canal this morning back to their side of the bank we still thought the problem was with the Centaflex but after closer inspection it was discovered the problem was actually with the gear box (at which point my heart sank as you can imagine). It turns out, despite researching on the net and getting what I thought were the correct answers, I had overfilled the gearbox oil which had led to the forward gears becoming smooth and slippery! Dave (from Oxley Marine who is an absolute legend!) found on checking the gearbox that not only was it too full but that the oil in there was not a healthy colour at all. After multiple cleanouts with diesel though the colour started to lighten and we started to get some normality to the gearbox. In reality the gearbox is pretty shot but thanks to Dave's ministrations and by mixing the ATF oil with 50ml of diesel we're able to keep on for hopefully a while longer (hopefully long enough to save up for a new gearbox!!). I can't recommend Oxley Marine enough - they're genuine, fantastic people who wanted to help and keep us running and lots of other people who we'd met on the way up the Staffordshire Worcestershire canal had also been saying really positive things about them. All the best and thanks for all your replies Martin
  14. Thanks - it's all making a bit more sense now - at least I won't feel completely in the dark when I speak to the engineers tomorrow! Martin
