I installed a Solix 15 SI GPS, 360 Imaging, Delta Pro 3 bank charger, 3 group 31 Duracells, 8 gang switch panel, and a Terrova 80 I pilot link with bluetooth. Spent more on this than the boat(1448 Lowe) & motor(25 Merc 2 stroke) new. My wife (my financial advisor) actually talked me into the Solix. I was looking at the Helix.
