I can't find the email with the exact quote, but I seem to remember around 9K.
Of course you would then need a transmission, and the prm 260 would have been my choice, and that was 3500 I think. So entire package was like13K, which is not a bad price. But then additional fabrication for my use would have been a additional 10K I bet to install it and I would have lost a lot of my engine space for a genset.
Some interesting engine stuff from Steyr with AC generator which becomes electricpropulsion if desired built into the assembly between gearbox and engine. Had a quick look at our big boat show in QLD Aust. earlier in the year. No price before you ask I did not get into it too deeply.
Professional Boatbuilder Magazine had an article this month on "Niche Diesels" mentioning Beta and Steyr as companies that specialized in refits. simple rugged and reliable engines not sensitive to bad fuel,etc. Professional BoatBuilder magazine
I am interested in the "not sensitive to bad fuels" as it is not the engine that has the problem it is the injection system. Bosch invented and perfected the mechanical injection system and are in the forefront of modern electronic diesel injection. These injection systems are basicly copies made under license Nippondenso etc. So I do not see how they can be more or less sensitive to bad fuels. The filtration system may be more complex allowing a greater ability to remove contamination but this could be done on any engine. The metering system (pump) and injectors no matter what the brand do not like water.
