I have an '04 240 Sundancer with the Mag 350. So my fuel gauge and speedometer are not working. They worked at the end of the season last year. On the first startup this spring they weren't. I replaced the sending unit. The fuel gauge is the last gauge in the order. The speedo is next to last. I plugged them in individually in the place of a working gauge and still nothing. I ordered two new gauges and still nothing. Any ideas?
). I had the same problem. Mine were the oil pressure, speedo and fuel. They replaced my sending unit and checked the pickup tube for speedo and found no issue with the oil pressure. I can verify that the oil pressure is ok by scrolling through the digital display. The gauge was replaced. Problem still exists from time to time. Hit a wake just right and they kick back on. Which doesn't make a lot of sense. They are canbus and the digital never fails. Only the gauge. Best guess is to check connection on back of gauges.
