Hopefully 80% will be from cruising, but there are times the batteries need charging.

Using that pompous so and so Mr Smelly's term 'Hobby Boater' means our engine has done 0 hours tied up charging. More often than not the engine is stopped in a lock so it's easier to talk. It's mandatory to knock the engine off in all manned locks and courtesy on the unmanned locks on the Great Ouse anyway. Upshot of that is all but a couple of hours where I've been working on her have been with the prop turning and us underway  Battery charging when stationery is taken care of with a Genny 🚢👍 Another benefit of not running Widow Twankie's laundry on board is the engine isn't getting worn out cleaning the week's washing 👍 |

Last Beta lasted 24 years, so I'm not unduly worried, just a little disappointed. I used to know an old guy who ran a motorcycle shop and he jokingly used to say his warranty lasted 25,000 miles, or crossing his threshold whichever came first. Think he must work for Beta now. I wonder if it's an anti-liveaboard thing like some battery warranties that exclude live aboard boats? On Telemachus's point, there are strict instructions in the manual and on stickers on the engine NOT to run for battery charging at less than 1200rpm. Rog Oh well that’s new! Not in our manual from 2010/ no engine stickers. Obviously you can run it slower once the charge current drops off. The problem is that diesel engines don't really like being run at low rpm, even cruising speeds are too slow for them. From time to time I put my BMC into neutral when up to temperature and rev it on the limiter for 20-30 seconds, you wouldn't believe the amount of black crap this leaves blasted all over the bank and in the cut. |

Yes i know, but if the majority of the engine running time is cruising (albeit at a fairly low power on the cut) the the occasional period of static charging culminating at idling, isn’t going to make a significant difference. It has to be said that the Kobota is a much cleaner engine than a BMC, when we occasionally do a blast on a river (last time, on the Thames) there is no smoke or black crap, just power. And that is under load, not in neutral. |

I don't wish to be snobby, but the bmc was for j4 vans and such. Postman pat engines. 😂😂

Postman pat engines. 😂😂 Along with gensets and tractors  Good old fashioned little engine that can be taken apart and put back together with half a dozen spanners and a hammer. They were the engine of choice for hire fleets for good reason. A good deal cheaper than the slightly more powerful Perkins 4-107/8 They are from a bygone age though. |

Rumour has it many golfs were recycled bmc's.
Better add, 80's and 90's models.

Very easy to work on, all parts readily available etc. A bit noisy, and reluctant to start when cold without a lot of pre-heat but generally fairly bulletproof. |

A neat conversion would be weld one of these:- www.merlinmotorsport.co.uk/p/10-jic-7-8-unf-round-alloy-weld-on-female-boss-wf-037To the inlet manifold and then screw in,pipe and wire up one of these:- www.asap-supplies.com/thermostart-bonfire-heater-plug-for-perkins-4108Absolutely no way it will refuse to start with both heater plugs and a bonfire. BTW, I have a few spare long series drills for decarbonising the glow plug ports If you want one posting to you 🍻👍🚢 ETA video |

They also suffer the usual boat engine malaise - miserly boat owners!
They need looking after.
They need regular oil changes,
They need the heater plugs checking and ports cleaning.
They need to have the injectors cleaned and services at least once a century - many won't have been touched since the day they were screwed together.
Many are now ripe for having the injector pump overhauled (along with countless other DPA powered engines) before the input shaft seal fails and fills the sump full of diesel with the risk of trashing an engine.
They need the valve clearances checking at least once a decade.
They need regular fuel filter changes.
They need to have been (as John points out) installed by someone with half a brain and an understanding of how a cooling system should work.
Sadly they are lucky to get a couple of the above let alone all of them!
