depleted my 36-volt trolling motor batteries by

mid-day, and despite being on winning fish, my day was done. Instead of a winning payday, at tournament’s

end, I made enough cash to retrofit my boat with a new

charging system and bigger batteries with more reserve

capacity, so I would never fail again.

Boats built a decade ago are factory-wired for

profit margins, not designed to handle CIA-level modern


We expect too much out of our

boat’s wiring, and worse yet we are too

scared to fix the problem. Whatever fear

is keeping you from getting the electrical

performance you need, maybe this

article will help you overcome.

I recently took the plunge and

retrofitted my 2008 Ranger Z20 wiring

and battery system after much study

and deliberation. My project may

not fit your specific needs but follow

my journey and learn how to get the

electrical performance you want and


My demands on battery juice

include aerators, navigation and

courtesy lights, NMEA 2000 network,

multiple big screen fishfinders with quad

processors and ethernet network to

share waypoints, charts, and transducers, 3D Structure Scan transducer and software module, Active Target (live sonar) transducer and module, Point-1 Heading Sensor, four digital iCommand gauges, multiple fluid level and temperature sensors, 36v Ghost electric motor with autopilot, and even a YoloTEC power pole powering a GoPro camera all day. Add an underwater camera, phone charging and music, streaming football games on my HDS units, WIFI, Bluetooth, and more.
