Mounted scotty FF mount at front of yak. Drilled 3/4" hole behind mount using step bit into yak. Drilled 2, 1/8" holes into rubber stopper to pass tranducer wire, and power wire through. Ran cables through stopper and secured stopper into 3/4" yak hole for a snug fit.

Soldered, and heat shrunk power wire positive, to fuse holder, and other side of fuse holder to 9V battery clip positive that attaches to battery holder. Soldered and heatshrunk negative side of power wire to negative of 9V battery clip. Coiled wire with fuse holder, and attached to tie wrap secured inside Pelicano box on wrap mount.
