You have just crossed the TSS on your way from Harwich to Oostend.
There is hardly any wind.
You are motoring.
Yo have been going since before 1st light and have a good 6 hours to go at the boats best cruising speed.
Suddenly there is a major change of engine note and a clattering noise from the rear of the engine.

On investigation you find the exhaust elbow broken off just before the water injection point.

What are you next moves?

If it is just before the water injection point, it should be quite cool, so how about wrapping the elbow back in place with some duct tape?

Continue at half the usual revs.

You must be near Fairy bank with depths of around 15m and in places less. Do you have enough chain to anchor while you size up the situation, wait for wind and rest?

The break is the engine side of the water injection point.
Just after the bend.
I would say that this is the hottest part of the exhaust.

Half revs would put you in Oostend about mid-night.
To late for you 1st Duvel. /forums/images/graemlins/frown.gif

agree mostly, not much wind so can mooch about, quick setting epoxy first, we all carry some dont we? then bid up with a piece of the fire blanket we all carry for stove fires, then the duct tape, try and sail and save the donk till we desperately need to enter port. then get the credit card out!!

The part remaining on the engine.

The way I fixed it will be posted tomorrow.
I would like to see how others would deal with this.

Shut off rattly engine and motor home on the remaining one. If that fails as well, get the auxilliary out of the lazarette, attach to aux bracket and motor to the nearest port on that. If that fails, tie 20ft of rope to forward cleat, other end to labrador and start throwing sausages towards nearest port. . . . .

High pressure radiator pipe with jubilee clips either side of the break would work for me , but someone must have a more techie solution . You don't carry your own welder on board do you ? /forums/images/graemlins/wink.gif

Well that bit would be quite hot I reckon - so I'd go with a tube of this stuff:
http://www.caswelleurope.co.uk/epoxy.htm - perhaps backed up by baked bean tin , jubilee clips and fireblanket as suggested.

But - if you have no epoxy - and assume no baked bean and jubille clip - what about just the fireblanket cut into strips

Otherwise - get one the sat phone to those nice people at Beta ...

Inflate the emegency dinghy, let off lots of flares. Hit the emergency button on DSC and do a mayday on ch16 when DSC converts. Let off lots of flares. and bundle crew into liferaft. Along with DVD player so you can watch Pirates of Caribeann III. Lots of water so you can survive the next few hours.

This might mean a difference if you are south coast UK or mid ocean?

We left Harwich at 03:30.

Very little wind so we motored out with Mabel the autohelm doing the driving.
All went well.
We even managed to cross the main TSS with only 1 small deviation to avoid a ship.

We were about 1 mile clear of the TSS when there was a clattering sound from under the cockpit sole and the engine sounded wrong!

1st move was to stop the engine and clear out the cockpit locker.
I thought that something had got mixed up with the propshaft coupling at the back of the engine.
Once I had got down to the back of the engine I found that the exhaust outlet had broken just before the water injection point.

This was going to be difficult to sort.

There was little wind but we put the main up to use what little there was to keep us clear of the TSS and hopefully move on towards Oostend.

We also called another YBW.com forumite, “Morgana” who had left for Oostend at the same time as us to let him know what was happening.

I thought that we may be able to join the parts back together with a section of exhaust hose.
The hose is designed to be used in the wet section of the system, not before the water injection point. this area is a lot hotter.
We had to give it a try.

I cut a section out of the hose behind the water trap.
I thought that this was the correct diameter to fit the part remaining on the engine but I could not get it onto it.
there was a short section of hose that was a larger diameter between the rear of the exhaust outlet and the water trap.

I cut of a bit of this to try.
it was to big for the section on the engine but a perfect fit for the water outlet section.
There were 2 problems with this.

There was only a very short part of the water injection section before the inlet pipe and we did not seem to have enough jubilee clips big enough to fit the bigger section hose.

After some head scratching I decided to cut a slot in the hose and allow it to go past the inlet pipe.

This meant we has plenty of pipe to clamp to and we could use a slightly undersize Jubilee clip.

Once we had forced a smaller diameter clip onto the other end we managed to clamp it to the outlet on the engine.

I then put all the rest of the system back together, crossed my fingers and a few other things and started the engine.
Water was being blown out of the stern as usual and there was no sign of any water leaks in the cockpit locker.
There was some signs of exhaust gases blowing out.

Ran the engine for 10 mins and checked that the hose was not melting.

Seemed o.k so we ran it again for ½ an hour.
Seemed very hot but no major problems.
We decided to try sailing for a while to allow it to cool down.
2.25 knots under main and spinnaker.

It seemed that we would not be into Oostend until very late if we carried on like this.
I decided to push on, keeping an eye on the hose and keeping out of the cabin etc in case of carbon monoxide.

We let Morgana know we were on our way again.
He said that he had sorted a berth for us.

The hose held and we arrived in Oostend at 19:25, about an hour later that we would have.

Once we had moored up and sorted our selves out we made enquiries about a more permanent repair.
Another Forumite “Gupea” who had come over on the same day said that he had an engineer coming to do some work for him the following morning.
The chap said that he could re-weld the thing.
He did so that evening.

Wonderful service!
