Bought a new Garmin 93sv in the black friday sale. Went to work and engineered me a dash and bolted that baby on. Dash is bolted to fiberglass behind dash. Original was just held on by plastic anchors. Used old dash as template to cut out new one with dremel from sheet of dash composite i ordered on line. Ditched speedo gauge is it had not worked in years. Used dual layer of composite for extra strength.
Boat is a 2006 285 pro XL.
