Is there a heating pump? Is it running?

Good price. I've also just ordered two packs.

Shh! Don't tell anyone but they're all computers inside.

Than the UK perhaps; not the world (In 2012 dvla said there were 34.7 million vehicles on the road in the UK, of which 28.7 million were cars). 28.7 million * 101g = 2898.7 tons SOx The world population of cars passed 1 billion in 2011 = 101000 tons SOx So the top 15 largest ships produce approx 5% as much pollution as all the world's cars.

It's a Beta BV1902S (basically Beta 43 in acoustic enclosure). The Travelpower is a 5.5 kVA mounted at the top so there's more room I think than the non acoustic version mounted at the bottom. TBH I haven't looked since it was done at the beginning of August as I'd have to dismantle the housing.

Any damage at all to the Travelpower drive belt would prompt me to replace it immediately. I've had a lot fail due to alignment issues (up until recently when that was sorted out) with the TP pulleys. My belts generally failed because they jumped over the edge of the pulley and crashed into the next belt in. This results in belt shredding, often a vee section at a time; the 7pk becomes a 6pk, then a 5pk until it snapped. The long narrow sections of rubber can work their way down the crankshaft, behind the inner pulley. If this happens, there is a real risk the shreds can work their way into the oil seal and tear it. I've had this happen twice in seven years, The first time, all the oil was dumped into the bilge in a matter of minutes, second time causing stead drip of oil being flung around the engine compartment.

The super silent solution has its alternators in a completely different arrangement. Photo: http://www.betamarine.co.uk/inland/Beta_SuperSilent/supersilent_inland.html You can see the silver Travelpower at the top left of the engine where the engine alt is under the standard arrangement. The engine alt is at the bottom left where the domestic alt normally is and the Domestic alt is at the top right. I wonder if this is related to air flow inside the acoustic housing, or a matter making it all fit inside the more restricted space.

All sorted. By the excellent Gand Junction Boat Services at Gayton Junction. The Travelpower alternator was moving on its mount, causing the pulleys to misalign and the drive belt to jump off the back of the crankshaft pulley, into the next belt. Now the mount has been stiffened, the belt stays in place. Beta themselves appeared to be unfamiliar with the Travelpower mounting arrangement at the top of the engine, specifically used for the super silent version of the engine even though there's a picture of it on their web site. All's well that ends well, except for my wallet.

1. Check your lines are tight enough. 2. Hang a fender or two between the hull and the side. Yes. People are nosy. The ones who don't look are probably boaters.

20th century boatmen seem to have favoured either flat cap or trilby: You can't get much more traditional than Joe Skinner

Wouldn't the magnesium ones still react first, effectively protecting the aluminium ones until they were gone?

All the belts off; waggled it and it's not loose. No sign of any play at all.

Just been back to the boat this afternoon. Removed all the belts and gave the pulleys a good heave back and forth. No play at all. This is with aluminium pulleys on a 2008 Beta BV1903S (Beta 43)

We've got the box with a Beta 43 inside (BV1903S) and hospital silencer. I'm pleased with it. With all the boards off the engine is as silent as under soundproofed boards. With our boards on it's very quiet. I could make it quieter with more soundproofing under the deck boards but don't consider it necessary. It takes about 20 minutes to remove all the wooden framework above and the box itself from around the engine. It's never been an obstruction to servicing - the surrounding rear-cabin engineroom imposes the main strictures on access, not the acoustic box. There is a handy little hatch on top so you can reach the oil and water for daily checks.

Has anyone changed one of these themselves? What size puller did you use for the pulley? I'm trying to decide if I can tackle it myself. We've got the usual twin alternators plus Travelpower (2008 aluminium poly-v pulleys). Last time I paid somebody to do it but I'm reasonably competent and would love to save the money. The chap who did it last time said he needed to shorten his puller as the engine is in a cocoon and access to the front end is tight.

It's not one with an amplifier in the base of the aeriel is it? If the power connection to the base of the aeriel has failed, the performance would be affected.

Resolved. A wad of toilet paper jammed in the inlet port on the cassette was preventing the connector being withdrawn from the cassette. I removed the cassette by disconnecting the cassette valve assembly from the cassette. I was then able to reach the inlet port to clear it and finally remove the cassette inlet port from the base connector. Not quite as revolting a job as I was expecting.

To confirm, it's a beta acoustic housing. That's where the BV1903 is housed. It's likely to be the main propulsion engine, as it's in a narrowboat. Can't see the prop shaft from this picture but I'd guess it runs under the raised floor between the back hatch and the engine housing so it's unlikely to be a hydraulic drive. We've got the same arrangement with a Beta 43, but with deck boards covering the engine as well,

Thanks all. Yes, the lock is disengaged. The cassette moves about an inch before jamming. I suspect the filter may have lifted somehow. Can't think of anything else. I'll see if I can find a flat bar to slide between the cassette and the filter on my next visit to the boat next weekend.

I can't get the cassette out of the cradle. It slides about an inch and then won't budge any further. Has anybody seen this before? I can't see anything jamming but then the cassette is in the way. Seems to be something perhaps on the right-hand side.

Ours is a 5.5KVa Travelpower on a Beta 43. Beta did supply a 7.5KVa one for a short time but no more. If using full capacity the revs need to be about 1500 but it copes in tick over for everything else. It does need an eye kept on the drive belt, though as it tends to eat them.

That link leads to a combi inverter/charger kit, not 240v alternator. I've got a Dometic Travelpower; modified Bosch alternator and dedicated inverter, driven from the engine. Cheaper than a stand-alone genset, but not quite in the same league as it requires the main propulsion engine to be running, being driven from it by a belt. I'd say that the 5.5kVa Travelpower is a useful alternative to a 5kVa genset, but a compromise when compared directly.

It's not a replacement for an inverter like a Victron MultiPlus, as that device runs off the boat's domestic batteries. A Travelpower set-up does have its own inverter to convert the output from the Travelpower alternator to 240v AC but this cannot use the domestic battery bank to make 240V AC when the engine is not running. There were three different Travelpower units provided as an option by Beta at different times. The most common one is the 3.5kVA, least common was a 7kVA unit and slightly less rare is the 5.5 kVA version. The 7kVA unit was only supplied for a short time because there were issues with transmitting enough power via belts.
