Bukh vs Farymann

[Major_Clanger]

I'm considering buying secondhand either a Bukh DV10 or a Farymann 10hp (Kubota based). I know both are regarded as reliable units but which would you choose, and why? I think I'm leaning towards the Farymann because spares are more plentiful and cheaper. Boat is a Co26 with little space for the engine.

Be good to have some opinions please.

Neither. Bukh is too big and heavy and are you sure the Farryman is Kubota rather than Hatz based?

Probably first choice would be a Yanmar 1GM as this is the lightest, simplest and most freely available engine. Alternatively a Beta/Nanni 10 would give you 2 cylinders and freshwater cooling in a similar size package albeit a bit heavier. They are, though probably less freely available secondhand.

You will only do this job once and fitting an old fashioned (Bukh) or unusual (Farryman) engine is perhaps not the best choice. Stick to mainstream brands.

I’d go for the Beta 10, great little engine and would fit nicely in a Co 26, I fitted one in my last boat which was an Invicta 26 which is very similar, never had any trouble with over the 18 years before selling the boar last year.

Thanks chaps... I wish I'd kept the 13.5 Beta I'd planned to install, but it was going to be a tight squeeze so I sold it a while ago. Yanmars are fine but for the noise and vibration but I take on what you say about the Bukh and Farymann (def NOT Kubota although the vendor swears it is).

It'll probably be a Yanmar, if I can find one at a fair price. Thanks again.

The 1GM is very little smaller than a Beta 13.5. 20mm shorter and a bit bulkier at the rear because of the extra cylinder. I replaced one with a Nanni 13.5 and it went in exactly the same space except the mounts are in a different position fore and aft and higher relative to the shaft centreline so had to add a packing piece to the bearers. Other than that it was the easiest replacement job imaginable.

Look for another Beta/Nanni. You won't regret it.

Spare parts for the Bukh 10 are generally readily available, I think, though expensive. Consumables - filters, etc, - are all (IIRC) standard automotive, so cheap, though.

I'd be surprised if a DV10 was smaller than a Beta 13.5, though - the Bukhs are hefty lumps - unless it was one particular dimension that was critical. (I did actually investigate swapping those two very engines between a couple of boats I owned, but can't now remember exactly what the dimension differences are. (Bukh taller, shorter length, slightly narrower at rear and wider at front? Definitely different sized exhaust and water inlet pipes; prop rotation reversed; Bukh much heavier.)

I wonder whether a Yanmar YSB 12 would fit? Perhaps too wide?

Cancel that, what a daft idea. Another outdated engine with future spares issues.

One may have realised by now that I'm trying to achieve all this on a tight budget!

 

[Tranona]

Definitely not. Much to big, heavy, outdated and now the NHS dentist service is so limited you would have big bills!

I have a twenty year old Farymann that has never missed a beat. It is horribly noisy - it's like having a cement mixer in your living-room.

I keep thinking I should modernise, but it is so simple that any job on it can be done with a boy-scout's toolbox. It has a large flywheel, which means it can easily be started by hand. I can have engine even if I have total electrical failure on the boat. It can be run at massively different temperatures and still work - depending on whether its raw water is fresh or salt, and there even exists an air cooled version. One surveyor exhorted me to hang on to it at all costs saying "I have seen those engines pumping water in South African mines where they have been running non-stop for 20 years."

So I guess I'll continue to hate it but keep it. Bit like my Taylor's stove.
