Cheers matey, let us know how you get on with the problem as i had the same problem but mine was due to a knackerd gearbox rather then the transducer but tried the same as mentioned before finding out it was the box lol...
the one off the diesel 200 should fit it, im not sure if its the same but if it is you can have it cheap arse, as i need that gone lol, the zr should be on the road in the coming weeks so keep an eye out
