You must have a water-temperature sensor or a temperature-capable transducer.
The temperature offset compensates for the temperature reading from a temperature sensor. 
1.  Measure the water temperature using the temperature sensor or temperature-capable transducer 

that is connected to the chartplotter.

2.  Measure the water temperature using a different temperature sensor or thermometer that is known 

to be accurate.

3.  Subtract the water temperature measured in step 1 from the water temperature measured in  

step 2. 
This is the temperature offset. Enter this value in step 5 as a positive number if the sensor 

connected to the chartplotter measures the water temperature as being colder than it actually 

is. Enter this value in step 5 as a negative number if the sensor connected to the chartplotter 

measures the water temperature as being warmer than it actually is.

4.  From the Home screen, select

5.  Enter the temperature offset calculated in step 3:

For the GPSMAP 6000 series, use the Rocker or the Numeric Keypad to enter the 

temperature offset. 
For the GPSMAP 7000 series, use the on-screen keyboard to enter the temperature offset.
