We pride ourselves on supplying the highest quality aluminium boat trailers, designed and built for rugged Australian conditions. Like any vehicle, all trailers require maintenance. Adhering to this Maintenance Schedule will serve you with a quality Wahoo Boat Trailer you can trust for many years.
Brake Line Instructions
Steps to Boat Trailer Fitting
- Set winch post to length of boat
- Check bearing buddies and hubs heat
- Sink trailer
- Winch boat onto trailer
- Drive trailer onto firm, level ground
- Adjust rear bunk supports
- Set winch post
- Set Bow Y-Support or Bow boards
- Set centre rollers (if fitted)
- 10 Final set winch post
- Secure boat to trailer- Winch is not for securing boat to trailer
- Set tow hitch weight- 8 -10% of boat weight (Check Tow bar is correctly rated)
- Check tyre pressure - 45 - 65 PSI
- Test drive and check bearings and wheel nuts
Always ensure correct tow weight prior to towing.
- Grease bearings buddies and Tow Hitch
- Trailer Flush
- Lanox every 3 - 6 months
- Hand-break adjust first 100km (if applicable)
- Check bearings every 3 months
Ensure your boat is adjusted to your trailer. Our trailers are designed as universal trailers, there are two main adjustments - Rear support bunks (width and height) and Bow Y-support (height) or bow boards (width, height, angle). There are also optional centre rollers (height).
Drive on/Float on Bunk/Skids
The main supports are the Bunks or Skids. They are set up towards the rear of the trailer either side of the keel. They can be adjusted horizontally to fit in with your boat hull and this will also determine the height your boat sits on the trailer. They can also be adjusted vertically to provide additional height adjustment. The drive on bunks / skids will align the boat to the centre of the trailer when the boat is retrieved and loaded on the trailer.
Bow Boards Guides
Centre Rollers and Bow Y-Support
Adjustable in the vertical plane (up and down), simply adjust to the keel shape of your boat. The keel rollers and Bow Y-Support are only designed to take up to 10% of the boat weight
Two main adjustments. The ability to move vertically and horizontally they have two purposes:
- Provides boat bow support and stability.
- Helps guide your boat on and off trailer.
Once the boat is fitted to the trailer correctly, the final task is to tie the boat down. A tie point is located at the front of the trailer, at the base of the winch post. Ensure you tie the front of the boat to the trailer. The other tie points are either side, near the tail lights, on the underside of the IBeam rails. You can also place tie down point anywhere on the main I-Beam rail - if required. You will require a long ratchet strap. Place the strap over the rear of boat from one side to the other. Tighten strap to anchor the rear of the boat. A safety chain should be positioned under the winch- this needs to be attached to the front of the boat.
The winch is only to retrieve the boat onto trailer, NOT to secure the boat to the trailer. Moreover, the winch is not design to pull your boat up the full length of the trailer. Wahoo Boat Trailer are designed to be a Drive on / Float on trailer. If you attempt to winch your boat onto the trailer the full length, you may damage the winch, trailer or boat.
Finally check tyre pressure and inflate to correct pressure usually around 40 - 55 PSI depending on the weight of the boat trailer combination
Check bearings are adjusted after fitting the boat as the cones can move when loading the boat onto the trailer for the first time
Checks and Adjustments required after first 5km with boat on trailer.
- Check and adjust wheel bearings (it is important to ensure the hub is packed full of grease). We recommend the use of bearing buddies/ protectors to help prevent water ingress.
- Check and adjust hand brake (if fitted)
- Grease the grease nipple on the 2 tonne tow hitch
- Check tyre pressures and inflate as required to correct PSI
Locations with high salt content and high humidity are prime for aluminium or galvanising finish to deteriorate very quickly. A high degree of care is required to slow the deterioration.
Use soapy water and brush to remove salt residue off the aluminium and galvanising after use.
Always wash out brake callipers with soapy water after each use to increase life of these items.
Ensure drain holes in the trailers axles and cross-members are kept clear and checked as a regular maintenance schedule. This will ensure any trapped water is cleared.
Using a hose press onto the drain hole under the centre of the axles and cross-members. Use a low pressure to flush the axles with clean tap water, this will flood the axle tube and help clear any salt residue.
The water will run out of the ends of the axles and the cross-members, cleaning out all salt water and residue. Run water for around 5 minutes.
Failure to carry out the above cleaning process can reduce the life expectancy of your trailer.
Bearing Buddies Maintenance
Bearing buddies / protectors are recommended for all our Wahoo Boat Trailers, Bearing buddies are designed to keep water out of the bearing hub.
Prior to your trailer entering the water, it is important to wait until the hubs have cooled.
When cold, pump grease into bearing buddies, until plate at back starts to move. This will fill the hub of grease, therefore eliminating water protruding into the hub
Wheel Bearing Maintenance
As with any vehicle, it is good practice to get any trailer checked by a profession mechanic every 6 months to avoid costly on road costs. Alternatively book into a Wahoo Boat Trailers dealer for an accredited Wahoo service. We strongly suggest a Wahoo Service every 12 months
Check wheel bearings and brake adjustment within the first 5km of using the trailer.
Check and service wheel bearings every 3 - 6 monthly for regular boat users
If the wheel does not rotate on the axle smoothly, replace bearings. This should be carried out by a professional mechanic or a Wahoo Boat Trailer dealer for a service.
Grease the coupling every six months or when no grease present on the shaft
It is recommended to inspect axle components at least twice a year for loose bolts and breakages. Spray axle and hubs with lanox or similar product after washing trailer
Brakes require service every 6 months.
Brake adjustment for the mechanical override system can be adjusted at coupling bracket and should be bleed at the calipers using the handbrake lever.
Ensure swing-up jockey, wheel when swivelled from the horizontal position to vertical, the spring loaded handle and extension pins lock securely into both holes in the jockey wheel mounting plate. Lubricate and Lanox regularly to keep rust away.
Check for cracked wiring and damaged lenses and all functions of the LED’s are working at least every 6 months
Regularly check for the correct inflation pressure and uneven tyre wear. Tyre rotation should be carried out every 6 or 12 months depending on trailer use.
Do not overload your winch, use it only for the application it has been supplied for on normal ramp conditions. Ensure winch strap is dry. If wet, unwind strap to dry out. This will avoid rust on drum and strap from deteriorating. Oil the winch shafts, bushes and gears as needed.
