That was just about all I managed to find about it, but if I am to buy them it would be nice to have some more detailed info.
The engines were (I am guessing here but it sounds likely) taken from the Swedish Navy´s Spica robot boat when they were taken out of service, most military engines were taken out of the vehicles by blowtorch and pliers so there is little hope of finding one with its ECU attached.
I am still awaiting a reply from the seller, because of the age, bulk and weight of the engines I am not prepared to pay very much for them. If the engines comes with a cut cable trunk they are worth even less.
Would make a nice addition to the jet collection though.
I might have some info about them..... they were used on the SRN4 Hovercraft operated by Hoverlloyd and then Seaspeed in the UK. My grandfather was the technical director of Hoverlloyd when they setup the hoverport and did a LOT of development with the british hovercaft coporation. If you have an email address I will see if I can email you the stuff I have... not sure its totally relevent to the engine, but might be of interest.
Just checked and I have an exploded drawing, an oil system diagram and some test data...
