Craig..
We used the Nordsgog. in our Foutain, it interfaced fine with our Garmin Chart plotter. We used the NEMA out feed no problem. The bezel in Gaffrig worked fine, not sure of the size of your orginal speedo. Be carfull!! that is probably the heaviest piece of equipment you can put on your Bullett..never saw a boat with one installed that didnt slow down 3-5 mph. :p

Hey Randy,
As much crap as we had in the water all year, I never had a pickup tube last more than an hour!!! My handheld gps worked all of the time.

Craig223, If you use just one attenna for both units you will have to have the gps c.p. on for the speedo to work. I don't need the gps chart plotter on all the time so I used 2 attenna's. Tom

craig if you take a hole saw the same size as the existing hole then put that inside the new hole saw it will use the smaler saw as it guide
