Trailer Service

One major component of trailering your boat is the proper maintenance of the entire trailer from brakes, lights, bearings, tires and a wide variety of other items. If you fail to complete regular service on your boat trailer severe consequences can happen from damage to your boat or trailer; you may also cause someone else to get hurt. Don't let this happen to you; service your trailer regulary.




Idenified as GAWR (Gross Axle Weight Rating) and found on the trailer's VIN plate, usualy near the trailer tongue, this tells you the max weight all the axles on the trailer can carry, The two types of suspension found on boat trailers are the leaf spring and the torsion axle. The leaf spring system is been around for many years and is designed to bend when it hits a bump so that the boat being carried remains stable, The other type of system is the torsion axle which operates as a single unit at each end of the trailer axle and provide a much smoother ride. They are more expensive.


Bunks Or Rollers:

Your trailer holds the boat in place with either a series of rollers or with a number of long boards (Bunks), Be shure to inspect the carpet as well as the long board for wear. The same will apply for the roller system on your trailer.



Located on the trailer tongue, many actuators have a master cylinder that will hold your brake fluid. As the trailer pushes into the slowing vechicle, the mechanical actuator activates the brakes on the trailer. You need a actuator that is designed for either disc or drum brakes. The other type of brake system is the electrical system which will activate when the brakes are applied from the tow vechicle.



Boat trailer lights are either incandesent bulbs. (which has been standard for years). The newest type of lights for trailers is the LED system which burn much cooler and last longer, Always before every trip make shure to check your trailer lights every time you go on the road.



Boat trailer tires have a "ST" (Special Trailer). or the words "Trailer Use Only" on the sidewall, Please make shure when replacing tires that the are for trailer use only. When checking trailer tires air pressure please note that they have a higher pressure rateing than your vechicle. The correct trailer tire pressure can be found on the side wall or on the identification plate on the front of the trailer.



Every state has different rules about trailer brakes, (Please check with your local state or call a professional). Their are two types of brake systems they are the drum and disc brakeing system, drum systems have to be adjusted every 3,000-4,000 miles while disc brakeing systems dont have to be adjusted they are self adjusting, both systems should be flushed every time the trailer is put into the water.
