Ballast sending unit

[kdrouet]

I have a 2008 Mastercraft CSX220 and just started to have problems with my front ballast tank. The tank fills but does not register on the Perfect pass display. How easy is it to diagnose the issue and what is most likely the problem (float, sending unit, both???)?

Thanks,

Keith

I've got a 2008 MS200 with the exact same problem...dealer replaced the sending unit but this did not fix the problem. Not sure what they will try next.
