Interesting thought getting hot water from an air cooled engine. I'd have thought the best way would be via a belt driven generator and an immersion heater. But that's not "free" heat, you would need to burn more diesel to get the electricty, via a fairly inefficient engine and a fairly inefficient alternator. |

Because it's in the boat that ticks all the other boxes. Personally it wouldn't be a deal-killer for me although it would need consideration on a case-by-case basis because as has been noted they're all old. Worst case, engines can be changed if you have to do it.

That's true but I was just thinking about the best way to get hot water from an air cooled diesel engine, not specifically about the recovery of rejected heat. |

Thanks for all the replies people, maybe my first post should have also said which are good engines to look out for. So Vetus are expensive for parts, what about Isuzu and Barrus Shire etc seem to be a few boats around with these engines. I would ideally like a boat with an engine that produces hot water.

Isuzu get some good reviews from owners. will have the option of a calorifier circuit for hot water.
Barrus do the Shire units which are Yanmar based which is a long standing well respected Japanese manufacturer. They also do one called a Barrus Shanks which I think is a Chinese base unit. Does not mean it's rubbish but I think they are a bit cheaper. Again it will do hot water.
Beta marine are good solid units as are Nannidiesel. Both use Kubota engines which are definitely OK.
There will be a lot of different boats about and as @nemesis suggested earlier the engine is not necessarily the deal breaker.
Plus of course a poorly maintained modern engine could end up being worse than a well looked after old engine.
BMC 1.5 is not such a terrible engine but then I would say that as I have two in one of my boats and they are very pleasant.

Beta, Beta or if you must Nanni (Nanni sevice is crap) I reckon Nanni do a slightly tidier job on the marinising but when I repowered my barge 11 years ago I did buy an engine from Beta Marine for it. ETA this sort of thread is definitely prone to choice supportive bias. |

They are good units. My mum ran a BV1505 in a 55 foot NB for 12 years while I had the Russell Newbery in my 55ft nb. The RN is more traditional and some brass but that Beta was a bloody good engine and took up a lot less space.
I would recommend Beta partly because I chose to buy a new one.
In terms of second hand inboard engines I have owned my list is
Lister SR2
Russell Newbery DM2
Sabb 2G
Lister Petter LPW2
Petter PJ4
Perkins P4
Perkins M90
Kubota twin (Kubota marinised)
BMC 1.5 X 2
Only new engine purchased was a Beta 90.
However if I did replace the BMC 1.5s in Dulcinea I would be very tempted to put in a couple of 3 cylinder Yanmars as long as they were for keel cooling.

Kubota, Isuzu, Yanmar. Things in common: all Japanese, all current.

Not sure about the Isuzu. I think there are some issues with spares for some of these.

Remember Bukh, proper marine engines, not glorified vehicle/industrial units.
Avoid cam belts, so that's Ford XLD and Lombardini in typical NB sizes

naughtyfox has a little red thing where the engine should be. Good units indeed. Not greedy, a nice sound and high build quality. I'd definitely be happy with a Bukh. Another reliable one is the Sabb. There are a few about. I put a 2G in a 40ft narrow boat in around 2007 which I had for 2 years. It was a great engine. Very nice item I think it's still in the boat. Kubota are remarkably good units. I had a Kubota Marine twin 750cc with a little PRM box on it in the Colvic. Running up and down the Thames all over the place it was totally reliable and clean running. Wonderful little engine. Not sure how old it was but there was a receipt for £1005 for engine and gearbox new so I guess 1980 ish probably. If so that was a really good item to be running that well after nearly 30 years.
