Most boating trips that end early end on the trailer. A spring check takes an afternoon.
Wheel bearings
Check for play and heat after a short drive, and grease or repack bearings on the schedule in your trailer's manual. Bearing protectors help keep water out after launching.
Lights and wiring
Test brake, turn and running lights with the tow vehicle. Corroded plugs and grounds cause most failures; clean them and use dielectric grease. Submersible LED lights hold up far better than incandescent lights at the ramp.
Tires
Trailer tires fail from age and low pressure more than wear. Check the date code and inflate to the pressure on the sidewall. Carry a spare that fits.
Bunks, rollers and winch
Replace worn bunk carpet and cracked rollers that can damage the hull. Inspect the winch strap for fraying and the bow stop for cracks.
Tie-downs and safety chains
Use transom straps and a bow safety chain, cross your trailer safety chains under the tongue, and check the coupler latch every time you hitch up.
