thanks for the info. and your right about tracker wanting a serial number. I also found out that the tv18 was actually made by fisher boats. i called fisher and they also wanted a number. I was told byt the Fisher parts department to get a look a a newer tv18, check to see if the fit might be thaq same and use the serial number from a newer model to order a console. I was also told tracker only stocks consoles back 5 years.
