Well, Day 2 really as we decided it was too late to go anywhere by the time we got down yesterday. There was a Plan. Today was a bit manky, forecast-wise, but we reckoned we could get in a run to Weymouth today, then be away sharpish the next morning to Plymouth.

Set off at 1300 today and the boatr was running very well, thanks to fresh antifoul and polished sterngear. Southampton Water was fine, the Western Solent a little lumpy but we figured the true test would be once we cleared Hurst Castle. And so it proved. Christchurch Bay was blowing old boots with 25 knots of wind and more water over the top than I can remember being out in before. So we cleared Hengistbury, still planning on rounding Anvil Point and carrying on for Weymouth, but by the time we were 3 or 4 miles out it became obvious that we would be taking it on the nose all the way.

Then the starboard tacho dropped to zero, but the engine carried on running. A few minutes later, it started up again, then spent the rest of the day working intermittently. No idea what the one downstairs was doing, but that's a job for tomorrow. Discretion being the better part of valour and all that, I decided th Poole would be a good place to go, and changed course accordingly. Bang on cue, a mile out from the Swashway and we get a very heavy vibration on the port engine again.

Down to one engine, bashing through some serious lumps and rolling like a pig, I'm very glad we decided to turn for Poole, as the thought of being out on the real clag on one engine does not appeal. Dolphin Haven (or whatever it's called these days) is full, as no-one bar us has ventured out today, so we loiter on the Town Quay while I dive into the engine bay. The flexible part of theport coupling has started to break up, so after a quick call to BD Marine, we're up to Cobbs Quay.

They're tryuing to track down a replacement coupling and will get over and fit it as soon as possible, but forthe moment we're going nowhere. On the positive side, I'm now getting very good at single engined manouevring...
 
Tachos dropping out prob just moisture. It sounds like you had a bit of that. Bit of a booger about the port engine. Was that the one you had the vibration on a couple of weeks ago?

When I read that I thought exactly the same thing, id get whoever to check the whole alignment of both engines while they are there as there has to be a reason why the coupling has failed, and yes I know its a job for a midget in your engine bay!!!
 
I had a fly bridge taco that used to mess about. Now it just is double revs all the time and sits on the 5000 rev stop.

Suspected your engine fix might not be the end of the job. Watch for weeping behind the stern gland. That was a bit before my shaft bent double and wizzed the stern gland round before loosing it completly.

Hey ho happy days. Hope yer mended soon. Luckily you got vibration, I got none, till a big BANG.
 
Yup, same engine/shaft that was 'repaired' last week or the week before. Last time the engine mount had vibrated loose and let the arse end of the engine drop hence th evibration and shaft alignment problem. Once we were into Poole and tied up on the Town Quay, I could see the coupling bulging abnd breaking up. Rang the engineers (the ones I paid only yesterday) and they said, "Yes, I guess we should have changed that coupling when we had the chance..."

Indeed.

Your patience is an inspiration. I am sure I would have had to count to 10 before responding to that!

I hope they are able to quickly fix it for you so you can go back to enjoying your holiday.

Yes we caught you reading the News Of The World once. You said you'd got it given.:):D

There is some thing going on here, not got to the bottom of. I had broken mounts, broken couplings, broken gear boxes for years. It finally bust its guts.

Dunno what your problem is. Mine seemed to be bad engine mounts.

Nuff said......



I have to agree with hlb here - what caused the mount to fail ? - and this in turn caused the breakup of the flexible coupling.

Shame its happened now however but Poole harbour is'nt bad for trips around the bay is it?
 
Well, apparently the nut on the outboard rear engine mount had vibrated loose and wound down the thread, allowing the mount to drop. That in turn put the shaft out of alignment, causing the vibration and shearing one of the coupling bolts. All that was put right, but it had also clearly damaged the flexible part of the coupling as well. After two hours running, the flexible spider in the middle of the coupling has distorted, so hopefully replacing the coupling will be the end of it...
 
Horrible....

when you are on one engine, but at least she didn't sink!!

That deep horror when the propulsion stops! Then when it's fixed there is another vibration?? surely the engineers should have realised the strain on the coupling from the previous incident?

Since my minor engine stopping events, the horrid sight of the rev counter needle at 0 with the alarms wailing below like dimented banshees it's taken me a while to build up confidence in the boat again.

I hope you get it fixed and things settle down for you and just work like they should.

Many years ago, I had a Princess 435 and we were in the middle of the Channel en route to Guernsey when there was a sudden bang from down below and the boat dropped off the plane and started to curve to starboard. I couldn't understand what was going on because both engines were still going. I had a look in the engine bay and immediately saw that the flex coupling from the s/b engine had sheared. Then I saw that the s/b engine appeared to be lying at an odd angle. Basically, all 4 engine mounting bolts had corroded and sheared and the engine had dropped off it's mountings breaking the flex coupling as it did so. Then I saw quite a significant amount of water coming in through the s/b sterngland, obviously caused by force of the shaft moving as the engine fell off it's mountings. That was scary enough but when I inspected the port engine, I saw that 3 of the 4 mounting bolts had sheared also and the port engine was held in position by just one mounting bolt. I immediately called Solent coastguard who luckily were still in range and informed them of our predicament. They offered to send a lifeboat but I said we'd return to the Solent on the port engine and see how it went. We motored at minimum speed on the port engine and fortunately the bilge pump was able to keep pace with the water ingress from the s/b sterngland. We made it to Hamble Point some hours later, who had been advised of the situation by the Coastguard, and were immediately lifted out of the water.
Moral of the story. Regularly inspect your engine mountings! It had never occured to me to do so up that point
