Product Questions

I have a 2020 basscat with a 2020 mercury 250 pro xs 4 stroke S# 2B738472 . It has a Mercury Smart craft gauge that has all the engine data . This gauge has the features to look at the fuel tanks but isn’t hooked up . I’m looking for the correct wiring harness that would let me see my 2 fuel tanks .

Hello Chris,

I am very sorry, but we are not able to cross reference Mercury components to specific motors or to each other. About all we can suggest is to contact a Mercury dealer to get the optimum harness part number, then go from there.
