As said above, many things to consider. Is this going to be your “from now on rig” or are you going to flip it in a couple of years. If the former, then yes, repower, update graphs and make it yours.

If the latter, youll not see the investment back out in a couple of years.JohnJones Trolling Motor Services870 773 3474Motorguide/MinnKota/PowerPole/Lowrance/Humminbird
