We'd pondered being more nomadic for a years but never really had a plan. Following an unexpected conversation with a chap in a field at the summer solstice, we thought a narrowboat might be a good idea. We mulled it for a few months. Then decided to hire one for a weekend, neither of us ever having set foot on a boat before. We enjoyed that and a few months later, at new year, we bought a boat. We still think we're slightly mad but it's also the best thing we've ever done

The only thing written on the original plugs is "HS 10.5 V" A search of the interwebs returns nothing that looks right. Next step is to take one to an auto parts place. The point about the taper seal is a good one. No seal or washer on the new ones. I also recall not all of the old plugs came out with that seal in place so I'll have to check what's down the holes!

I didn't spot any numbers when I had them out but I didn't give them a good clean. When I have another look at the weekend I'll see if I can get a match. These where £26 each which is bad enough!

Sorry, I didn't attach the image properly the first time! Seats to the tip is definitely longer on the new plugs.

I'm replacing the glow plugs in my Shanks 4-40 engine. The old ones came out ok which was a relief. But the new ones are not all screwing fully home. The two plugs do not look the same, new one has a longer thread and hot tip (see attachment) I checked with Barrus that the part number of the plugs is correct for this engine (RDG210A18) and they say yes. So either they are giving me the wrong info or the plugs currently fitted are not correct. The engine is quite old now so it's quite possible that the plugs have been replaced in that time with the wrong ones. I'm wondering if the shorted thread length on the original plugs means that crud has built up at the bottom of the bore so the longer ones won't screw down far enough. The other possibility is that the longer tip is fouling on something inside the chamber (I believe it's an indirect injection engine). I was losing the light when I tried this the other day so this weekend I'll pop the old plugs back out and have a good look down the hole. Any suggestions on other things I could check?

Thanks folks. That helps clarify things.

We've just receive the purchase survey from our first ever boat. Most of the things on the list make sense but one has me a bit baffled. "It would be best practice to weld the forward base plate seam externally." It's just an advisory but I'm curious why this should be done? I'll probably give him a ring to ask but I thought I'd ask here as well. cheers Adam

Hi all Just introducing myself. My wife and I are are in the process of buying a 58 foot narrowboat to be liveaboards. This boating lark is all very new to us but we're looking forward to getting going! cheers Adam
