For complete instructions on setting up a new NMEA 2000 network or 

expanding an existing one, see the other document packed with your 
EP-90R, "Setup and Installation of NMEA 2000 Networks, General 
Information" part number 988-0154-173. If that document is not 

available, it can be downloaded free from the Lowrance web site. 

The EP-90R Pressure sensor can provide pressure data for the 

following categories: Atmospheric Pressure, Engine Boost Pressure, 

Engine Oil Pressure, Engine Water Pressure, Fuel Pressure, 

Transmission Oil Pressure and Pitot Speed. 
WARNING: 

Pitot Tube (Water Speed) 
We recommend installing the EP-90R near the boat’s original 

speedometer.  

If your engine does not have a speedometer hose, you will have to 

purchase a pitot tube kit to use the EP-90R Pressure sensor. For 

pitot tube installation instructions, refer to your pitot tube 

installation manual. 

The following steps cover the recommended installation of the EP-90R. 

You will attach the EP-90R to a pitot tube hose in the same manner. 
1. Remove the pressure hose from the boat’s speedometer. 
2. Clip off the end of the pressure hose that was connected to the 

speedometer. This will help ensure the pressure hose will fit snugly on 
the EP-90R hose barb attachment. The hose-barb attachment 
requires a 1.4" (6.35 mm) hose.
