2011 Centurion Enzo SV230+ - just bought the boat used last year and still trying to get the manuals for it but my ballast pumps are not working this year - no issues with them last year. I could hear the pumps start up when I was getting the boat ready last week (out of water - just switched them on/off very quickly). I put it in the water and it sat for a couple of days and then went to use it - batteries were low - low enough that were not even running the bilge. Had taken on a bit of water - pumped out fine but now cannot hear my ballast pumps at all and blower is not working....also noticed my gps/perfect pass and even the dial speedo isn't working.... any ideas? Seems electrical to me but not sure where to start.
