    I bought a 98 sundancer 290 recently with twin 5.0s with smart craft. It used to alarm every 2 Mins with sea pump ckt lo and show no pressure on port. I replaced the sensor, all is clear now and reads well. Starboard doesn't alarm, however it also read 0. So I replaced it as well. After I did, the same sea pump ckt lo alarm came back and still reads 0 but for Starboard this time. I went back to the old sensor bc I don't want to hear the alarm, but any ideas? I would like a reading. Temp is normal on both motors and everything was recently gone through by a mechanic. Can I reset smart craft? Or maybe there is a bad wire somewhere.

    Did you use Mercruiser sensors?

    There have been issues with the off brand sensors.

    It's an OE sensor but not Merc. Same exact one I used on the port engine and it worked perfect. I can try the Merc brand sensor though
