Trailer Information

Maintaining the trailer

Galvanised trailers are coated in a galvanised finish. This chemical process bonds very hot liquid zinc to the trailer and its components. The zinc covering forms a barrier that protects the steel under the zinc. The environment in which the trailer is used, stored and maintained determines the level of deterioration of the zinc. In areas of high humidity, high salinity or poor water quality, it is common for the zinc finish to deteriorate very quickly. A high level of care is required in these environments.

Trailers must be washed thoroughly after use and stored in a dry, well ventilated area. Salt residues may drop onto your trailer from the hull above while in storage. If this occurs, wash as soon as possible.

It is normal as the zinc surface ages that a white powder (calcium carbonate) forms on the galvanised components. Calcium carbonate is normally evident in the low drainage points of the trailer where salt residues collect.


Connect the coupling to the tow bar by placing the coupling directly over the ball, pull up the handle and let the coupling slide down over the ball then release the handle letting it bottom out on the top of the coupling. Mechanical, hydraulic and standard couplings need to be greased every six months or when there is no grease present on the shafts.

Safety Chains

Connect the safety chain to the vehicle with D shackle supplied with the trailer. Do not use a padlock between the safety chain and the car while travelling.

Jockey Wheels

When manoeuvring the trailer on either concrete, lawn or a soft surface, the jockey wheel should be in its wound down position. This enables easier manoeuvring of the trailer.

Axles and Springs

It is recommended that the suspension components be inspected at least twice yearly for any evidence of loose u-bolts, bolts and corrosion or breakage of the leaf springs. Painted and galvanised suspension components should be sprayed regularly with products such as lanolin based sprays.

Wheel Bearings

Wheel bearings should be checked at least every 90 days and before putting the boat away for any lengthy period. They should be replaced every 6 months depending on trailer use.

For a quick check, jack up the wheel and give it a wobble from side to side:

If there is slack in the bearing you will need to retighten the axle hex nut and give the wheel a spin.

If it is noisy you will need to change the bearings.

If you re-assemble the hub and there is evidence of water, this will also render the bearings unfit for use and require replacement.

Routinely check the wheel hubs whenever you stop for fuel or refreshments. If the hub feels abnormally hot, inspect the bearings before continuing. On extended trips, carry spare wheel bearings, seals and races.


If your trailer is braked, the braking system is a disc brake over-ride system with either mechanical (cable operated) or hydraulic (fluid operated) brakes.

At any sign of deterioration, mechanical brake cables need to be replaced. To adjust the tension on mechanical brakes ensure the boat, motor and all equipment are on the trailer. The cable can then be adjusted at the front pully or the adjustment bolt on the calliper. Remember to leave enough slack in the cable to allow for the flex in the trailer while underway.

Trailers with a gross mass over two tonnes are fitted with hydraulic electric braking system and disc braked on all four wheels. This system needs an in-car electronic electric brake controller to operate it correctly, owner supplied and fitted by an auto electrician. The braking unit must be mounted high over the coupling and kept clear of submersing and high pressure cleaners at all times.

It is important to check the trailer’s brakes for operation prior to departure on each trip.

Alloy and Steel Wheel Stud Patterns

Alloy 9”, 10”, 13” and 14” wheels - stud size: 7/16”, pitch circle diameter: 108mm (41⁄4 commonly called HT).


Correct tyre pressures are located on the yellow sticker at the front of your trailer and on the tyre’s side wall. Regular checks for the correct inflation pressure and uneven tyre wear should be carried out. It is recommended for maximum tyre life that the tyres be rotated on the rim every 12 months or 6 months for heavy use. It is also recommended that a spare wheel is carried along with the tools required to change them.


  • Wheel nut torque on the trailer wheel and the spare wheel should be checked at regular intervals.

Trailer Frame Drainage

It is important that the drain holes throughout the trailer frame are kept clear and checked on a regular basis. This allows for drainage of any trapped water to exit the frame.

Trailer Lighting

Lighting and wiring need a six month inspection to ensure that there is no cracked lamp lenses, no corrosion has got into the wiring, lamps and that all functions of the lamps are working.

Check tail lights and turn signals work when attached to the towing vehicle. Before backing the trailer into the water, disconnect the light plug from the car. This will greatly reduce the chance of blowing out the trailer lights.

Hand Winch

Never overload your winch, use it only for the application it has been supplied for on normal ramp conditions. All winches are fitted with webbing straps (the same material as seat belts). This material is designed for higher load rating and braking strain, compared to equivalent cable.

When you finish with the trailer remember to check that the winch strap is dry to avoid rusting on the winch drum. Oil the winch shafts, bushes and gears periodically when needed.

Fitting Boats to the Trailers

The boat should sit hard on all keel rollers. Galvanised parts should not be touching any part of the hull and the side Teflon skid pads should be positioned as far out from the keel as possible then to be adjusted up firm against the hull of the boat.

If your boat doesn’t come up straight after trailer adjustment and all skid pads and roller measurements are correct, then check that the boat sits horizontal in the water. Even a very slight lean will bring the boat up to one side. Move fuel tanks, fishing gear etc to bring the hull horizontal to the water.

The boat should be fastened to the trailer by a cable or strap from the bow eye to the winch, plus a safety chain or cable from the bow eye to the winch stand or trailer tongue. The stern of the boat should be tied down to the trailer. Tie down points are fitted to podded models. These are to be used as tie down points. The boat transom-to-trailer tie down straps and winch lines are designed for normal towing conditions on paved roadways and moderately rough secondary roads (at slow speeds only). We recommend the use of additional straps or rope tie downs for securing the boat to the trailer, particularly for longer trips or whenever you expect to encounter rough roads. The use of a motor support bracket is also recommended.

Trailering Tips


  • Remember to close all hatches and doors in the boat before trailering. Store all loose equipment, so it cannot slide, fall or blow out. Ensure the canopy/bimini is down and secure and that all seating inside the boat is also secured. It is possible for seats to move while travelling – ensure all seats are strapped down and securely fastened.
  • Do not use your boat as a trailer. Do not carry excess weight in the boat while trailering or travelling on the water.
  • When reversing, engage the reverse lock on the trailer hitch. This will lock on the trailer hitch and stop the trailer brakes operating when reversing. Remember to disengage the lock when the reversing operations are complete.
  • Too much or too little tongue weight will cause difficult steering and tow vehicle sway. Generally 5% to 10% of the boat and trailer weight should rest on the tongue.
