Nothing on exhaust apart from pipe i replaced

I read that that boat was 72ft but do we know what beam it was @magpie patrick? I did a google search but came up with no information on beam and it does look quite slender so perhaps less that 7ft bream.

Ah, ok. I had visions of some sort of commune, moored up alongside a wood in the middle of nowhere!

Did you look that up on Google? 😉

I came down Napton this morning. Posted to the lock beam was a notice stating opening times 10am - 4pm.

Do you have any sort of silencer, or water separator in the exhaust line, if so it might be worth taking it out to see if anything odd has happened inside it? Boats of that age often had a rubber expansion box that looked like a pair of cones pushed together.

One other thing. If the hot, out connection on the Webasto runs downhill from the boiler, be prepared to loosen the joint to let air out of the system, if the Webasto pump does not cause it to self bleed. If it does not then the boiler will fire up, run for a sort while, and then shut down, with the Webasto connection being hot, but the rest of the hose/pipe still being cold.

I initially refilled my Webasto system with 50% mix. The radiators refused to get hot. I drained it and remixed it to a 25% solution and all worked well.

Well I have now made sure the water scoop under boat is clear, still no difference

you’re too modest for your own good 👍 which makes for conversation having said that there’s a good Wikipedia page on John Scott Russell and his discovery of the phenomenon: ” I was observing the motion of a boat which was rapidly drawn along a narrow channel by a pair of horses, when the boat suddenly stopped—not so the mass of water in the channel which it had put in motion; it accumulated round the prow of the vessel in a state of violent agitation, then suddenly leaving it behind, rolled forward with great velocity, assuming the form of a large solitary elevation, a rounded, smooth and well-defined heap of water, which continued its course along the channel apparently without change of form or diminution of speed. I followed it on horseback, and overtook it still rolling on at a rate of some eight or nine miles an hour [14 km/h], preserving its original figure some thirty feet [9 m] long and a foot to a foot and a half [30−45 cm] in height. Its height gradually diminished, and after a chase of one or two miles [2–3 km] I lost it in the windings of the channel. Such, in the month of August 1834, was my first chance interview with that singular and beautiful phenomenon which I have called the Wave of Translation.“

Thanks Tony. It's a reservoir/expansion setup, so I don't anticipate needing a pump. Good shout about the antifreeze/water mix - I've heard people say 40%, which seems on the high side to me!

Hello, Anybody able to recommend a boatyard to blast and epoxy the baseplate and side bottom of a 60' narrow boat please? I'm on the Leeds Liverpool, Lancashire end so North West only please. Happy to do the epoxy myself, it's the blasting facilities mainly. I know a couple of places that will do it but seeing if there is a cheaper option somewhere. Thanks Andy

You may find it cleaner to use something like a drill pump to drain the system down if the drain point is within the cabin. If it is extended into the engine area (assuming a rear engine setup) you can drain into the bilge rather than into shallow containers. Mix the antifreeze and water BEFORE refilling the system and on no account exceed a 30% mixture, 25% is probably better. If your system happens to have a pressurised expansion vessel, rather than a reservoir/expansion vessel, then you may need a pump to refill and pressurise it.
