Just got a new used boat. It is a bass tracker 175. The electronics on it need some major work. Where's a good place to go to have it repaired? Also, the fish finder on it is shot. I am looking to pay ahywhere from $300 - $500 dollars on a new one. Does anyone have any suggestions?

Look at the Lowrance 510 it is a good color unit in the upper part of your price range. You can add a few bucks and get a sonar/gps like the 522.

Not sure where you live, or what units you need help with, but might give them a call.

Of course the best place for Sonar repair is the folks that made it, call them also (really try them first).
