Pulling Winch vs. Lifting Winch

When selecting a winch for your boat trailer, it’s important to note the difference between pulling winches and lifting winches.

Pulling winches are designed to horizontally pull loads, such as dragging a boat onto a trailer. They use a ratcheting mechanism to apply steady tension, making them ideal for boat trailer applications.

Lifting winches, on the other hand, are built to vertically hoist and suspend loads, like raising an engine or lifting a equipment in a shop. Using a lifting winch for pulling—or vice versa—can lead to mechanical failure or unsafe conditions. For boat trailers, always choose a pulling winch with the appropriate weight capacity.

Boat Trailer Jacks vs. Other Types of Jacks

Boat trailer jacks are designed specifically for marine use, setting them apart from other types of trailer jacks like A-frame or drop-leg jacks commonly found on utility and RV trailers.

Unlike standard trailer jacks, which are primarily built for stationary support, boat trailer jacks are equipped with wheels or casters, allowing for easier maneuvering when hitching, unhitching, or positioning the trailer in tight spaces. They are also constructed with corrosion-resistant materials, such as galvanized steel or zinc plating, to withstand frequent water exposure and harsh marine environments.

Many boat trailer jacks feature a swivel design, allowing them to pivot out of the way when not in use, which is especially useful for boat ramps and uneven terrain.

Tips for Your Boat Trailer Parts

1. Rinse your boat trailer after saltwater exposure

Keeping your boat trailer in top shape ensures safe and hassle-free towing. One of the biggest threats to trailer longevity is rust and corrosion, especially if you frequently launch in saltwater.

To prevent damage, rinse your trailer thoroughly with freshwater after each saltwater use, paying close attention to metal components like the frame, axles, and suspension.

Choosing galvanized or aluminum trailer parts can also help resist rust. Additionally, applying a corrosion-resistant grease or protective coating to exposed metal parts, such as hubs, bearings, and couplers, can extend their lifespan and maintain smooth operation.

Regular maintenance and proactive care will keep your trailer road-ready for seasons to come.

2. Inspect your boat trailer lights regularly

Ensure your brake lights, turn signals, and running lights are working properly before every trip. Water exposure and road vibrations can loosen connections or cause corrosion over time.

3. Grease wheel bearings often

To prevent overheating and failure, it is generally recommended that you grease your wheel bearings at least once a season or every 3,000-5,000 miles. Use a marine-grade grease for added water resistance. Be sure to consult the owner's manual from the manufacturer for specific guidelines.

4. Check your winch and strap

Your boat trailer winch plays a crucial role in safely loading and unloading your boat. Before every trip, inspect the winch drum, gears, and handle for signs of wear, rust, or damage. A failing winch can lead to slipping, difficulty cranking, or even failure when retrieving your boat.

The winch strap or cable should also be checked for fraying, cuts, or weakening fibers. A worn strap could snap under tension, making it difficult—or even dangerous—to secure your boat. If you notice any damage, replace it with a high-strength polyester strap or a galvanized steel cable for maximum durability.

5. Inspect your safety chains

Safety chains act as a backup in case of coupler failure. Always cross them under the coupler when hooking up your boat trailer and check for rust or weak links.

6. Test your trailer brakes

If your boat trailer has brakes, test them before every trip. Whether you have electric brakes or surge brakes, proper maintenance ensures safe stopping power on the road.

7. Secure your cargo with proper tie-downs

Use ratchet straps to keep your boat securely fastened. Loose or worn straps can lead to shifting during transport.

8. Check tire pressure and condition

Underinflated tires can lead to blowouts and uneven wear. Check your boat trailer tire pressure regularly and replace worn or cracked tires before they fail.

9. Lock your boat trailer for security

Invest in a coupler lock, wheel lock, or hitch pin lock to deter theft when your boat trailer is parked or even if it's hitched up to your vehicle. A small investment in security can protect your valuable equipment.

10. Buy parts from a reputable supplier

CURT boat trailer replacement parts are available both locally and online. Use our dealer locator to find a trusted retailer near you or shop online through one of our official retail partners. Whether you need a winch, jack, safety chains, or suspension parts, CURT makes it easy to get the right equipment for your trailer.
