Nordic Tug 37

Hi all

My new to me 2007 NT37 appears to have the fresh water tank and fuel tank senders not working. The water tank just shows full on the gauge, and the 2 x fuel tank show empty on the smart view display.

Are the senders on NT a known problem in failing, just seems strange that all three are not working. Not overly worried about the fuel as there are sight gauges on the tanks, but the water level gauge would be good to have working.

Am I missing something obvious?

It is possible that the first owner has not done calibration filling ever on the smartcraft system (fuel).

There may also be electrical corrosion somewhere water/fuel tank wires.

Here's a link to the fuel meter kalibration, read also your NT folder for smart craft tank calibration which is done in 4 stages, as I recall.

I thought the water tank had a similar sensor as the link where a fuel tank could so help you?

We have a 2002 NT37. Fuel and water tank sensors are not working. We installed a sight glass for the water tank using the water pump supply line fitting.
