I think Minn Kota could hit a big market by offering a Link upgrade.
If a new boat comes with Lowrance standard and an Ultrex it is doubtful the Link option is offered.
Most folks will replace electronics far more often than trolling motors.
When my Lowrance units are obsolete I will go back with Humminbirds.
I would be nice if MK lets us go with the "whole boat" concept without having to replace a perfectly good TM.
