Sure - you just need to make sure you get the correct sender units. Two items to worry about, electrically, are number of gauges driven and the full scale resistance of the sender (usually ID'd by OEM of the gauge they are compatible with). If you have two instrumented helms, you'll need "dual station" sender units; if not, then the standard single stations senders are what is needed. The newer VDO pressure gauges show a higher pressure as the resistance of the sender goes up. Best way to ensure compatibility is to get the gauge number of its label...next best way is to measure the full scale resistance required using a potentiometer and an ohm meter.
