    It wouldn't be my first choice.
    The ones I'm familiar with are 1 and 2 cyl. air cooled, terribly noisy and badly balanced, but there may be other ones as well.

    They have a product range of marine, or marinized, water-cooled diesels also. No idea about them beyond brochure data and pricing, but atleast the smaller models seem to have a little different head and cam design.

    CDK, all the Lombardini engines above 40 HP are 4 cylinders, except for the largest one, which is 5 cyl. You have perhaps worked with small sail drives, up to 20 HP? They have 2 cylinders, which are in effect difficult to balance perfectly - but that, I guess, is more a matter of physics of moving masses than of the engine brand. ;) Lombardini engines have a pretty good reputation for reliability and fuel consumption among Italian boaters. It is a 90 yrs old company, their engines have been powering thousands of tractors, trucks, gensets, industrial vehicles etc. over all these decades - it should tell something about their value, I guess.

    @Jemora:
    IMHO, you should also take into consideration the availability of dealers and maintainance facilities. Lombardini network in the UK can be found here: http://www.lombardinimarine.it/en/rete_wor.asp?nazione_eng=United Kingdom - try to see if there is someone in your zone.

    Cheers

    I would be looking for something more traditional and something that sounded nice to listen to on those quiet stretches of the Manchester canal.

    An old 300 RPM single with a big flywheel springs to mind.

    We have been using Lombardini 4 cyl turbocharged engines in commercial applications and are very satisfied with them and the backup from the factory. This engine comes in non-turbocharged version as well; both smooth running at 3000 rpm, which is comparably low rpm for this size of engine. Iveco are painting them red and selling them under their name for marine use.

    No, I have not. It is exactly like I said, I'm familiar with single and twin cylinder Lombardinis only, used in small tractors and generators.
    If they know how to build reliable, quiet engines I do not understand why they also build engines that simply fall apart within 2 years.

    "They have 2 cylinders, which are in effect difficult to balance perfectly - but that, I guess, is more a matter of physics of moving masses than of the engine brand. "

    This is a common hassle that the engine mfg understands.

    Usually there is a DESIGNED SWEET SPOT rpm Where the engine is as smooth as any other.

    Normal cruise , at the sweet spot.

    This will usually not be published , but for a guesstimate I would look for the torque peak.

    A call to the factory and a question to an engineer might at least get the RPM to avoid.
