Engine vibrations

The engine in my narrowboat, a 3 cylinder Thornicroft 60 on oil filled mounts, is fine when on tickover, but as engine speed increases it starts to vibrate until between 800 and 1000 rpm the vibration of the engine is quite violent. Then at 1100 rpm the vibration stops and doesn't reoccur at higher revs. This has occurred over the last year, before which it ran smoothly at all engine speeds . Any suggestions as to a likely cause. The mounts are about 15 years old.

Blacking over vinyl tar

I found out recently that coal tar products are being banned from January 2019 and my narrowboat was blacked with Rylards Vinyl Tar from new last year and I understand that this product is coal tar based. I've also heard that bituminous blacking doesn't adhere to vinyl tar, so I was wondering which blacking I can use when the time comes, and for touching up any scrapes?
Many thanks

Northern ring plaque

Dear Waterways World,
I wonder if you can help me. In your Annual magazine you publish an article that describes all the recognised cruising rings. We are currently doing the 'big northern ring' and really enjoying it. We like to collect the commemorative brass plaques as we complete such challenges and display them on our boat. However, we cannot find a plaque to represent this cruising ring.
As you describe this ring in your magazine I wonder if you can you advise me where to find a plaque or advise who makes them so I can ask them if they have any available?
Yours sincerely
Heather dawes.

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.
