After the initial PR splash, there has been very little in the news about it!! Volvo have occasionally used this installation in their ads!! I don't know of any other Cat yard in OZ following them!! But then it could just be due to local conditions as the water is pretty thin in many of the popular boating areas in OZ!! This is why I went to 250 HP Suzuki's on my 40 ft Cougar Cat after owning a Nooscat with Yanmars in it. Second benefit is that one can keep the props clean by keeping them out of the water when the boat is not in use. The boating world needs a light diesel outboard!! Cheers!

How about retractable rim-drive units? You might work these partially retracted as well. And you could service them without hauling the vessel each time??
