Marine Electronics Katherine

Boat wiring, batteries, solar, chartplotters, sounders and radios for Katherine boats, installed for Top End salt and heat.

Workshop in Winnellie, on the boat at the marina, ramp or mooring. Free consultation and a written quote before any work.

Katherine is the NT's third-largest urban centre and the service hub for pastoral, mining, defence, and remote-community work. Equipment runs in dust, heat, and long supply lines — anything we touch here has to be serviceable on-site by people who won't be flying us back next month.

What we fix

Wiring and rewires

From a new switch panel to a full rewire with tinned cable, proper crimps, labelling and a diagram at the end.

Batteries, charging and solar

AGM and lithium banks, isolators, DC-DC chargers, solar and inverters sized for how you use the boat.

Plotters, sounders and radios

Consultations

We provide clear scope, timing, and cost expectations before major work starts.
