Thinking about selling my boat instead of trading it in when I upgrade. 2015 179trx with a 115 4 stroke. Has lowrance HDS Gen2 Touch, 9 at console, 7 at the bow. Linked with structure scan(lss2). Yep I know Gen2 is no longer supported. I have navionics chip for it and it works great. Mounted on precision sonar plates with gimble mounts. Motorguide digital pro 82#,24 volt. Onboard Minnkota 3 bank charger. It has about 50 hours if not less on it. Most of that from this year. What do you think it should go for?
