Hi guys, i want to fit an engine before the winter sets in to protect the water pump and crankcases. I have found this one on E-bay.

But i have heard that the original Yamaha product has been failing so i dont want to fit that one. Is the one on E-bay the Yamaha guard? If so could people give me a few pointers as to what sort of choice i have got? I only want the guard to go around the bottom half of the engine.
Thanks in advance for your replies....
