Ranger 520R and 521R Series Trolling Motor Battery Switch Mounting Bracket

Set up your Ranger 520R / 521R the right way with a purpose-built battery switch mounting bracket designed for clean installs, easy access, and long-term reliability. Engineered around the R-series rear compartment, this bracket helps you place the cutoff switch where it’s protected yet reachable at a glance.

Why This Bracket Matters

A properly mounted battery switch is more than convenience—it’s safety and serviceability. Quick access lets you isolate power for maintenance, charging, or emergencies, while a fixed location prevents wiring strain and clutter in the battery bay.

Designed for Ranger 520R / 521R Fitment

Built specifically for the R-series layout, this bracket follows the compartment geometry so the switch sits correctly without forcing awkward cable angles. The result is a professional, factory-like install that looks good as well as provides plenty of clearance between the bottom of the switch and the top of your batteries.

Marine-Grade Construction

• CNC-cut aluminum for strength with a durable, corrosion-resistant finish
• Stainless fasteners and Nylock nuts help resist vibration and loosening
• Built to handle long runs, rough water, and trailering

Compatible Switch Types

Works with common marine battery cutoff switches used for trolling motor or accessory banks (e.g., compact ON/OFF or mini-selector styles). Check your switch footprint to confirm hole spacing and stud clearance.

Installation Notes

• Mounts to a flat surface in the rear battery compartment
• Use marine-grade cable and properly crimped ring terminals
• Route cables to avoid chafe and maintain clear access to the knob
