I'm trying to figure out the best way to mount a battery (for a fishfinder) on my Tarpon 140. I have a 12V 10A battery - it's about 6" wide x 2.5" deep and 4.5" tall - weight at least 5+ pounds. I'm thinking because of the weight I want to keep it in centerline of the boat. I fish in the ocean - sometimes in pretty snotty conditions - so I really need it to be secure. Does anyone have any tips or suggestions on battery mounting?
Thanks in advance for any advice!
