    isuzu ... cheap, indestructible, simple.
    But ... high consumption, enormous weight.
    Note that an alpha romeo diesel, 2500cc, 68kg, 137kw.

    CatBuilder,

    Where exacally in the SE. I know most of the major suppliers from New Orleans to Pensacola.


    Personally I have owned most of the major brands, and dislike them all about equally, they all have quircks, so I would prefer the one with the best local support regardless of manufacturer.

    I would also look for engines that have been derated. This keeps the engines as a lower level of engine strain, and keeps them working longer.

    I'm still working out the HP details on this engine, but I'm looking for a small, 2 or 3 cylinder diesel I can marinize, or one that is already marinized.

    Somewhere around 18HP.

    I'm farther East than Pensacola, but more than willing to drive for a deal.

    I like old engines that are easy to fix like Perkins. The less electronics and turbos the better.

    I wanted to mount it on a shallow water boat, then I decided to mount two smaller ones.
    I mounted two Castoldi jet.

    with the gearbox, cooling, electronic etc.. ranges from 125 kg up.
    I don't think gearbox needed.
    For cooling, best thing is a cooler.
    The ECU must be reprogrammed.

    Of course in case of failure, who helps you?

    Hi Catbuilder,
    I recall pontificating on that topic elsewhere and agree with many that reliability and parts are important as is SIMPLICITY and robustness - NO turbo-chargers, NO common rail injection system, Be careful with the heat-exchanger as blocking/corrosion there is an instant boat stopper... Consider having the oil filter and fuel filter placed with EASY access for changing - I am contemplating a 5 to 10 litre reservoir for the engine lubricating oil where it is easily accessible and easily removed with the filter AFTER this added reservoir... that way all the sludge should fall to the bottom of this removable reservoir... - To change the engine oil remove and empty and clean the reservoir, change the filter, refill with engine oil and DONE with minimal fuss - My tiny 20hp (3 cyl 722cc) Nanni's have only 3 litres of engine oil - Far too little for long passage motoring so a conversion is being considered and special tanks made... - I would use the same idea if I changed over to 27hp Yanmar diesel outboards - ONLY when they fit LARGE (15"+ dia.) propellers and gear ratio to give 1200 max propeller rpm...
    Just my feelings...

    Considerations excellent.

    For these reasons, being able to do, it would be better "marine use" master of its own engine.

    Oversized heat exchanger and protected by Teflon, oversized oil sump, fan air force eliminated.

    The electronics ....
    Opting out means more fuel consumption.
    Worst departures.

    Keep it means having to keep the oxygen sensor and reprogram the ECU.

    For an engine of 20 hp, I believe it is appropriate to have it as easy as possible.

    There is also a fantastic alternative.
    A good electric motor, with an adequate package of patter and a generator in motion muted 24/24.

    Thanks, Masalai...

    but this isn't to propel the boat. It's just to run a HVAC system.

    I would love to have done this, but electric propulsion is too heavy:

    Generator (or two)
    Pair of electric motors
    Running gear
    Extra heavy wiring due to high currents

    I am putting together a high performance catamaran. Weight is the primary concern.

    This diesel engines I'm looking for (now) is just to push some refrigerant around.
