Your aluminum boat trailer is built for strength, corrosion resistance, and performance—especially when it’s crafted by Real X Trailers. But like any piece of quality equipment, it needs regular maintenance to stay in top condition. A well-maintained trailer not only protects your boat but also ensures safer towing, smoother launches, and fewer unexpected repairs. Whether you’re trailering down the coast or just heading to the local ramp, these five essential maintenance tips will keep your trailer road- and ramp-ready for the long haul.
1. Rinse After Every Saltwater Trip
Even though aluminum resists rust, saltwater is relentless. Over time, salt can cause corrosion, especially around hardware and moving parts. After each saltwater launch or recovery, rinse your trailer thoroughly with fresh water, paying special attention to:
-
Axles and suspension
-
Wheel hubs and brakes
-
Stainless steel hardware and fasteners
Don’t forget to flush out hard-to-reach areas where salt deposits tend to build up. At Real X Trailers, we use marine-grade aluminum I-beams and stainless steel hardware, but a regular rinse will significantly extend their lifespan and preserve that showroom shine.
Pro tip: Use a hose with a spray nozzle for better reach and pressure. For deeper cleaning, consider a salt-neutralizing rinse additive to eliminate residue.
2. Inspect and Grease Your Wheel Bearings
Your trailer’s wheel bearings take on the heavy load of your boat and absorb the stress of every road trip. Even if you have sealed or stainless steel hubs, water intrusion—especially from repeated launching—can still lead to wear or rust.
Every few months, or before long hauls, check your bearings by:
-
Removing the bearing cap and inspecting for any milky grease, rust, or unusual noise
-
Repacking bearings with marine-grade wheel bearing grease
-
Replacing damaged seals or bearings immediately
At Real X Trailers, we use high-quality hubs and components, but routine lubrication and checks ensure those parts go the distance. You can also upgrade to bearing protectors for added peace of mind.
3. Monitor Tire Pressure and Condition
Your trailer tires don’t just support your boat—they face sun, salt, and heavy loads regularly. Under-inflated or worn tires are a safety hazard and can leave you stranded.
Before each trip, make it a habit to:
-
Check tire pressure using a reliable gauge
-
Inflate to the manufacturer’s recommended PSI (found on the tire sidewall)
-
Inspect tread depth and sidewalls for cracking, dry rot, or bald spots
-
Don’t forget the spare tire—rotate it into use at least once a year to keep it road-ready
Real X Trailers offers premium tire packages specifically built to handle harsh coastal conditions, but regular checks are key to long-term performance.
4. Test All Lights and Wiring
Your trailer’s lighting system isn’t just a convenience—it’s a legal requirement. Real X Trailers includes submersible LED lights on every model, but saltwater, vibration, and age can affect wiring over time.
Before every outing, test:
-
Brake lights
-
Turn signals
-
Running and marker lights
Use dielectric grease to seal and protect wire connections from moisture. Carry spare bulbs or LED modules and a few basic tools—because the boat ramp isn’t the best place to troubleshoot in the dark.
If your lights flicker or fail consistently, it might be time to check ground wires or upgrade to a fully sealed harness system.
5. Examine Bunks, Rollers, and Mounting Hardware
The bunks or rollers on your trailer do the critical job of supporting your boat’s hull. Over time, carpet can wear thin, brackets can loosen, and rollers can crack—especially under the pressure of frequent launches.
At least once a season:
-
Inspect bunk carpet for fraying or bare spots
-
Check that rollers spin freely and aren’t flattened or cracked
-
Tighten all mounting bolts and brackets
-
Realign bunks or guides to ensure they match your boat’s hull contour
Because Real X Trailers custom-builds each trailer to match your boat’s exact dimensions, a snug, hull-friendly fit is guaranteed—but seasonal inspection helps keep that fit perfect and prevents unnecessary hull damage.
