Your Step-by-Step Boat Trailer Inspection Checklist


To ensure 100% safety on your road trips, thoroughly inspecting your boat trailer is extremely important. Fortunately, performing such inspections isn’t that hard and can be done keeping in mind this below-explained checklist.

Start By Checking the Condition of the Tyres & Also Perform Pressure Checks

Your trailer tyres should be checked regularly for signs of tears or rips. Also, if you’ve been using the same tyre for a long time; the rubber can get hard and start showing small cracks on its sidewalls. Look for such signs too, and if found, replace them immediately to avoid an unfortunate blowout.

You also need to inspect the tyre pressure.

  • If you own a touring type of trailer, then your tyre pressure should be between 45 and 65 psi.
  • And if your trailer travels more on off-roads, then the working pressure should be something between 32 and 45 psi.

Next Check Then Wheel Bearing, Hubs and the Trailer Axle

For this; you need to lift the wheel from the surface and wobble it holding both sides.

  • If you notice movements in your trailer wheel, then it is a sign that you need to replace its bearings.
  • Similarly, if you notice a rumble when spinning the wheel, then it is a sign that its bearings need replacing.
  • For the trailer axle, ensure it is straight, square and sits on the centre pin of the spring.

Thoroughly Inspect the Boat Trailer Brakes

There are usually 3 kinds of brakes used on boat trailers. The electromagnet brake which needs a controller, the hydraulic brake which consists of a reservoir on the trailer’s drawbar and mechanical disc brakes!

You need to inspect them individually for signs of wear-tear on its shoes and pads. If you are not happy with its condition find a reliable supplier of trailer spare parts in Sydney and replace them with newer ones. Also, check the fluid levels of the hydraulic brake.

Next Is Your Trailer’s Suspension

The key aspects to check for in your trailer’s suspension include as follows –

  • Broken or cracked leaves
  • Leaks in the shock absorber
  • Indications of leaf separation

Look to tighten all loose bolts and further inspect the bushes and bolts for possible wear marks.

What Else To Check For?

In addition to the above components; you should also focus on these trailer components.

  • Check the chassis and crossbars by looking for signs of welds, cracks or rusting issues.
  • Inspect your trailer lights and wiring properly. Remove the lenses and clean the dust and dirt inside. You can also take out each of the globes and ensure its connections are clean. But if not, then look to clean it using a rag or emery paper.
  • And finally, inspect the tow hitch and aptly lubricate wherever needed. Check for wear signs and if replacements are needed, get it done immediately.


Perform these inspections regularly and replace whatever’s damaged, worn out or broken with new parts procured from a notable supplier of boat trailer accessories who often sell such parts at budget-friendly rates and even offer impressive warranties.
