My gaffrig mechanical (water driven) speedo doesnt work. I blew air thru the hose and its clear. Are these easy to repair ? Also...how are these measured ? Mine is 4" across the front...and around 3 3/4" across the glass face. If anybody upgraded to a gps unit and has a white gauge...please let me know. Thanks.

They used to rebuild them for a fairly reasonable cost if you sent them back to the factory. I had mine done about 3 years ago. I don't know if you can still do that though.

i have one thats liquid filled thats a 4". i checked on having mine rebuilt but was cheaper to buy new non liquid

First of all, are you sure there isn't a hole in the line? I've blown holes in mine numerous times. Secondly, I have a non working GPS speedo, Livorsi, if you're interested. You would just have to send it back to them to get fixed. I'd take $100.
