Trolling motor LCDs are incredibly useful — but they’re also one of the most vulnerable components on a motor. In South African conditions (sun, heat, dust, water and long-distance transport), LCD failures are more common than most anglers expect.
This guide explains why LCDs fail, how to protect them, and what to do if yours stops working, so you can avoid unnecessary damage and expensive mistakes.
Why Trolling Motor LCDs Fail
Even quality motors can suffer LCD problems over time. The most common causes include:
- Sun & heat exposure – Prolonged UV and high temperatures fade screens and damage internal components.
- Water ingress – “Water-resistant” does not mean waterproof, especially around seals and buttons.
- Transport vibration – Long trips on rough roads loosen internal connections.
- Incorrect storage – Leaving motors uncovered on decks or trailers accelerates wear.
- Pressure washing – High-pressure water forces moisture past seals.
Most LCD failures are gradual — not sudden.
How to Extend the Life of Your LCD
A few simple habits can dramatically increase LCD lifespan:
- Always cover the motor head when not in use
- Avoid leaving the motor in direct sun for extended periods
- Disconnect power when trailering long distances
- Never use high-pressure water to clean the head unit
- Check that cables are not under tension when deployed or stowed
- Store the motor in a dry, shaded area when not in use
These steps cost nothing — but save a lot later.
Warning Signs Your LCD Is About to Fail
Look out for:
- Fading or dim display
- Ghosting or lines on the screen
- Slow or delayed button response
- Random screen resets or shutdowns
If you notice these signs, take action early.
What To Do If Your LCD Stops Working
Before opening anything or ordering parts:
- Confirm your exact motor model (thrust rating, year, series)
- Do not open the control head unless instructed — this can void warranties
- Avoid cheap, generic replacement screens
- Confirm compatibility before purchasing any replacement
Many LCD issues are repairable — but only with the correct parts.
Can a Trolling Motor LCD Be Replaced?
In many cases, yes — but it depends on:
- Motor brand and model
- Availability of compatible LCD units
- Lead times from suppliers
Some models require complete control-head replacements, while others allow LCD-only repairs.

Final Thought
A trolling motor LCD is an investment. Protecting it properly — and knowing how to respond when problems start — can save you frustration, downtime and unnecessary cost.
