Help with Yamaha Digital Speedo

[dbranco00]

I have a 1999 parker with a 2004 sinlgle yammy 225.
My gauge wont work at all now.
I need to buy a new one?
There is no part number on the gauge itself

Can someone help me with this? I have checked ebay but they look the same
with different part numbers.

Thanks
Dan
