Boat Towing & Trailering

Boat Trailer Parts, Towing Gear & Launch Ramp Essentials

Shop boat trailer parts and towing accessories for safer road trips, easier launch days, and better protection between home, storage, service, and the ramp. Find bow rollers, bow stops, trailer winches, brake actuators, hubs, bearings, lights, wiring, tie-down straps, safety chains, couplers, bunks, guide-ons, jacks, and trailer maintenance parts.

Trailer fitment can depend on boat weight, hull shape, axle rating, coupler size, brake type, wheel size, roller shaft size, and local towing requirements.

Popular Towing & Trailering Searches

Find the Trailer Part or Towing Accessory You Need

Use these links to narrow the collection by the part or job. When a dedicated collection is not available, the link opens a Marisol Marine product search.

Support & Retrieval

Rollers, Bunks, Winches, Stops, and Guide-Ons

The trailer should support the hull evenly, hold the bow securely, and help the boat load straight at the ramp. Match rollers, bunks, stops, shafts, brackets, and guide-ons to the trailer frame, hull shape, and boat weight.

Road Gear

Brakes, Bearings, Lights, Couplers, and Tie-Downs

Road safety depends on the trailer being rated, visible, connected, and secured properly. Check hubs, bearings, brakes, lights, tire condition, coupler fit, safety chains, and tie-downs before towing.

01

Secure the Boat

Use a bow connection, stern tie-downs, and properly rated straps so the boat cannot shift during braking, turns, or rough road conditions.

02

Check the Running Gear

Inspect tires, hubs, bearings, brakes, lights, wiring, coupler latch, safety chains, and the jack before every longer tow.

03

Launch With Control

Guide-ons, bunks, rollers, winches, and bow stops help line up the boat and reduce hull, trailer, and ramp stress.

Fitment Help

Measure Before Ordering Trailer Parts

Trailer parts often look similar but fit differently. Check roller width, shaft diameter, coupler ball size, axle rating, hub bolt pattern, brake type, light plug style, bunk bracket dimensions, and trailer frame size before ordering.

For rollers and bow stopsMeasure roller width, outside diameter, shaft diameter, bracket spacing, and the contact point on the hull.
For brakes and actuatorsMatch disc or drum brake type, actuator rating, coupler size, axle capacity, and brake-line configuration.
For hubs and bearingsConfirm bearing numbers, seal size, hub style, bolt pattern, spindle size, and axle rating before replacing parts.
For lights and wiringUse marine-ready lighting and confirm plug type, wire routing, grounding, submersible use, and corrosion protection.

Towing & Trailering FAQ

Choosing Boat Trailer Parts

What should I check before towing a boat?

Check tire condition and pressure, wheel bearings, hub temperature, brake operation, lights, wiring, coupler latch, hitch ball size, safety chains, winch strap, bow eye connection, and stern tie-downs.

How do I choose the right bow roller or bow stop?

Match the roller or stop to the shaft diameter, bracket width, trailer geometry, hull contact point, and boat weight. Measure the old part when possible.

Are disc and drum brake actuators interchangeable?

No. Trailer brake actuators must be matched to disc or drum brakes, trailer weight rating, coupler size, brake-line layout, and the braking system installed on the trailer.

When should trailer bearings be inspected?

Inspect bearings before long trips, after submersion-heavy use, if a hub runs hot, if grease looks contaminated, or if you notice noise, wobble, vibration, or uneven tire wear.
