Dometic fridge

I was told you can re-gas a Dometic fridge - it is a small one that runs off of 12 /24 volt and gas. Can anyone advise me please on the procedure and who in London might undertake the work?

Changing antifreeze

I have a Beta 43 with keel cooling and calorifier circuit. I want to change the antifreeze and would like to know the best way of doing it. I would like to flush the system through once drained before refilling with fresh antifreeze mix. Do I need to remove the hoses for the skin tank and the calorifier from the engine in order to flush with fresh water or can I flush without doing that? Many thanks

Windlass dimensions

I am looking at the ships fitter engineering a personalised windlass for me. The only dimensions that I am missing are the precise tapered mm slots that he will need to drill out which are needed for the mechanical or hydraulic gearing on the canal system. Thank you.

roof hatch

I hear that you have to be very careful in installing a roof hatch due to condensation. I was wondering what is out there that has been proven not to drip water/condensation. The boat is to have a full paint job this summer and am looking at placing a hatch of 500cm x 500cm if I hear of a hatch that does not drip!.

Propshaft and couplings

I have a Trentcraft 26. Front cockpit, front engine with a 5 metre propshaft running in the keel. The shaft is in two pieces and the rigid joint is loose. Can I replace it with a single shaft? Or is 5m too unwieldy? Also need new flex coupling and bearings - there are three in the keel between gearbox and sterntube. Two are noisy one has been castrated (it has no balls). Might fit new engine mounts too and Aquadrive? Recommendations and suggestions please.

Gas queries

Gas changeover valves with opso now have pol connectors on the hoses but my tanks are m20. Can I just use my old hoses? Otherwise the only changeovers I can find are ROI.
Also, Does nobody make a 15mm bubble tester? Seems rather dtupid to have to reduce from 15mm to 10mm then back up to 15

New Engine Mountings

We have had new engine mountings fitted to our Lister Canal Star Engine (LPWS4) in our 55ft cruiser stern narrowboat. The mountings are of a different design to those fitted previously which are apparently no longer available. Although the engine looks as steady as rock, there are vibrations in the boat which we didn't experience previously. These are very wearing except at very and very high speeds. The bow door stays now rattle whereas the bow-deck was previously area of complete tranquillity.
I wondered if the prop was misaligned but the boatyards says not and in any event the flexible coupling would compensate for any minor misalignment. The suggestion is that they will bed-in or they could be replaced with some different ones. Any suggestions as to how this issue would be best solved?

engine oil

hello you wonderful people, it is time for my barrus shire 1200 diesel engine built in 1999 to have its oil changed, i only bought the boat last august and the previous owner told me back then that the oil would have to be changed around april / may so now is the time, he did leave me a bit of the oil he last used which is barrus shire 10w 30 api cc, the problem is that there isn't enough , so i thought i could use what is left in the prm 120 gear box which i believe is ok as it says in the manual to use the same oil, please correct me if i am wrong, however i can not find this same oil on line even on the barrus web site, have they stopped making it or / and is there a replacement ?? any info will be greatly appreciated thank you and happy cruising.

Re-plating a Hull.

I am considering buying a 60' Narrowboat that needs its hull re-plating.Having seen overplating where weld is only applied to the sides of the hull I would appreciate your advice. To prevent sagging,surely extra weld points across the steel to the existing hull would be required. Please advise on a suitable spacing for such extra support.

Smokey Exhaust

I wonder if you can help. I have a Yanmar Barrus Shire 3-cylinder 3TN74 engine that continuously smokes smelly blue exhaust fumes.
The engine itself runs very well but I am getting tired of the diesel smell.
Have you any suggestions that can cure this?

Hyundai HY3000SI Generator inverter or similar

hello all you wonderful people at waterways world, i am not a liveaboard and have my 46ft narrowboat in a marina ,but visit at least twice every ten days, i have no access to shoreline but wired for it , i had the pleasure of using shoreline last month while blacking it and finally got to fully charge my two new 110ah agm leisure batteries via a sterling battery charger, it took around 7-8 hours for the float charge to finish but well worth it , since then i have had to recharge them running the engine, sometimes in idle which i believe isn't good for my barrus shire 1200. for those reasons and maybe using the vacuum on occasions i have decided to buy a Hyundai HY3000SI Generator inverter or something similar, it comes with 13 to 16 amp caravan adaptor leads , now , does that mean i can plug it in to where i would plug in the shoreline and let the sterling battery charger do the rest or would i have to charge each leisure battery individually , sorry for my ignorance but electricity is not my strong point, any info is of great help, thank you very much and happy boating.
