Connecting lowrance carbon nine to mercury SC 1000 speedometer

[snickers2]

How do you wire the lowrance carbon line to a mercury SC 1000 speedometer gauge so that it reads the GPS speed?

There are five wires in the HDS communication bundle:
Yellow (not the Yellow wake-up wire, the NMEA wire will be included with the other NMEA wires)
Orange
Blue
Green
Bare

Hook the yellow Lowrance wire to the white wire with Blue Stripe from the MercMonitor.
Hook the Bare wire to the Blue Wire with White Stripe from the MercMonitor AND hook both to ground. I used the ground at the fuse block under the dash.

Press Menu twice, select Network, Turn NEMA 0183 communication on, select NEMA 0183 Sentences. On the sentences screen, I selected all of them under GPS and all other categories.

Do a MASTER RESET on the MercMonitor after all was completed. Select Settings, then Speed, turn Pilot Tube OFF and Paddlewheel OFF. Turn GPS Enable to ON, and turn USE GPS SPEED to Yes.

Thanks for the information. I’ll try it and I’m sure it will work. Thanks again.

Mercmonitor and Smartcraft Speedo are two different gauges.

For the OP, the above procedure MAY work but the exact setup should be in your Smartcraft Tach/Speedo manual.

I got the SC 1000 speedometer to show The speed from the GPS by connecting the yellow wire to the white wire with the blue stripe and connecting the blue wire to the blue wire with the white stripe and it worked.
