Trans wheels for PVC boats of the type NDNDM (low pressure, non-rigid bottom flooring) are not just an accessory, but a necessary element for comfortable transportation. Without them, moving the boat along the shore or launching into the water becomes a test: the weight of even a small PVC boat (from 30 kg) combined with dirt, sand or gravel makes the process extremely uncomfortable. However, improper fastening of the wheels can lead to damage to the transom, PVC fabric rupture or even loss of the boat during movement.
In this article, we will discuss all stages of installation of transom wheels For the NDNDM boats, from the selection of mounts to the final adjustment. nuances of working with low pressure PVCYou can also find a comparison table of popular wheel models, a checklist for self-installation, and answers to frequent questions such as whether it is possible to attach wheels to a boat with an aluminum transom, or how to avoid corrosion of metal elements.
Why do transom wheels are necessary for PVC NDND boats
Boats from low-pressure (HPD) differ from classic high-pressure PVC boats in their softness, their bottoms are not rigid, and the transom is often made of the same PVC or reinforced plastic, which creates several problems when transporting:
- 🔹 Weight is distributed unevenly: without wheels, the boat has to drag for a transom, which leads to overload of seams and joints.
- 🔹 Risk of PVC damageSand, stones and driftwood on the shore can wipe or punctured material when dragged.
- 🔹 The inconvenientness of launching: even boat trolleys are not always saved if the transom is not equipped with wheels.
- 🔹 Storage problems: wheels allow you to easily move the boat around the garage or parking lot without the help of a second person.
Statistically, More than 60% of damage to NDND boats occurs during land transportationThe wheels on the transom reduce this risk by 80 percent by evenly spreading the load and lifting the body above the abrasive surface.
⚠️ Attention: If your boat has a NDNDM ferro-squamousCheck it for rust or cracks before you install the wheels, and fastening to a damaged transom can aggravate corrosion or cause bolts to break.
Types of transom wheels for PVC boats: which are suitable for NDND
Not all wheels are universal – for boats low-pressure It is important to choose a model that:
- 🔧 He has. adjustable height (Not to be able to hold onto the ground when the boat is tilted).
- 🔧 Equipped. shock-absorbing (To protect PVC from vibrations).
- 🔧 Suitable for soft-trans (unless it is reinforced with a hard material)
Consider the main types of wheels and their applicability for NDNDM:
| Type of wheels | Advantages | Deficiencies | Is it good for NDND? |
|---|---|---|---|
| Removable screeds | Quick installation, do not require drilling | Can be displaced when moving, limited load capacity | Yes (for boats up to 50kg) |
| Bolts (hard attachment) | Reliable fixation, can withstand a lot of weight | Requires transom drilling, risk of corrosion | Conditionally (with anticorrosion treatment only) |
| On depreciation brackets | Protection of PVC from vibrations, adjustment by height | More expensive than analogues, more difficult to install | Perfect. |
| Universal telescopic | Suitable for different types of transoms, easily removed | Can be used in intensive operation | Yes (with proper adjustment) |
For boats NDND the best choice will be depreciation or telescopicThey compensate for the softness of the structure and prevent overloading of the seams. If the transom is reinforced with aluminum, you can consider the bolt mount, but with a mandatory sealant treatment and anti-corrosion composition.
Preparation of PVC NDND boat for wheel installation
Before installation, you need to check the condition of the transom and the boat itself, especially critical for NDND, where the soft design requires accuracy.
Check the transom for cracks and rust (for metal transoms)
Clean the surface of dirt and sand (use a soft brush)
Check the pressure in the cylinders (should be within the manufacturer's norm)
Apply markings for fastenings (taking into account symmetry)
Prepare tools: drill, drill, sealant, keys->
If the transom is made of PVC, forbidden Drill it without reinforcement.
- 🛠️ Folding plates from aluminum or composite (distribute the load).
- 🛠️ Clay sealant for PVC (e.g., for PVC) Bostik 5205 or Polyurethane glue).
- 🛠️ Soft-pad screeds (for removable models).
For boats with aluminum transceiver:
- Handle the drilling sites
corrosion-predator(for example, zincor). - Use it. stainless-bolt (A2 or A4 according to ISO 3506).
- Install. rubber-washer between the bracket and the transmuter.
⚠️ Attention: When drilling PVC transom, use squirt Low drill speeds (up to 300 rpm) otherwise the material may "trend" or break.
Step-by-step instructions for fastening transom wheels
Let’s look at the universal installation algorithm by example. depreciation (The most reliable option for NDND) For other types of wheels, the steps will be similar to those adjusted for the mount.
Step 1: Marking and preparing the holes
1. Turn the boat upside down and clear the surface of sand and moisture.
2. Apply the brackets to the transom and mark the holes with a pencil. Use symmetry. laser-level Or roulette.
3. If a PVC transom, stick to the drilling sites reinforcement (You can either cut out of an old boat or buy ready-made ones).
4. drill holes with a diameter of 0.5-1 mm smaller than the diameter of the bolts. plastic-drill with a sharpening angle of 90°.
Step 2: Installation of brackets
1. Put on the bolts. threader (for example, Loctite 577).
2. insert bolts into the holes and fix them on the back with nuts with grover.
3. Do not tighten the bolts to the point - leave a backlash of 1-2 mm to compensate for the deformation of PVC.
4. Install shock absorbing bushings (if they are included).
Step 3: Wheel Installation and Adjustment
1. fasten the wheels on the brackets according to the manufacturer's instructions.
2 Adjust the height so that when the boat is tilted by 10-15 ° wheels do not touch the ground.
3. Check the free rotation of the wheels - they should not cling to the transom or cylinders.
For removable screed wheels:
- 🔩 Use screeds with a width of at least 25 mm.
- 🔩 Lay between screed and PVC rubber-stick.
- 🔩 Tighten the screeds evenly, avoiding distortions.
After installation, apply to bolts and screeds silicone lubricant This will protect them from corrosion and facilitate dismantling in the future.
Typical mistakes when fastening wheels and how to avoid them
Even experienced water-engineers make mistakes that lead to breakdowns.
- ❌ Tug-and-tug bolts → PVC deformation or a thread failure.
⚠️ Attention: The optimal tightening moment for PVC-transom is 4-6 N·m.
dynamometer. - ❌ Ignoring depreciation → The vibrations break the seams of the boat.
- ❌ Installation of wheels without strengthening the transom → PVC rupture under load.
- ❌ Use of steel (non-stainless) bolts → corrosion and jamming.
To avoid problems:
- Always use. soft-stack (rubber, neoprene) between metal and PVC.
- Check the mounts after the first 2-3 uses - the bolts may weaken.
- For boats weighing >50 kg, install double-wheel (Tandem) for uniform distribution of the load.
If after installing the wheels lufts or creaks, the reasons may be as follows:
| Problem. | Possible cause | Decision |
|---|---|---|
| The wheel is dangling. | Bolts loosened or sleeves worn | Replace the mounts or replace the sleeves |
| Screaming while driving | There is no lubrication or friction of the metal about PVC | Apply silicone lubrication, check the gaskets |
| The wheel clings to the balloon. | Incorrect height adjustment | Adjust the bracket or shorten the axis |
Maintenance and care of transom wheels
To make the wheels last longer, follow simple rules:
- 🔧 After each use wash the wheels with fresh water (especially after the salt water).
- 🔧 Lubricate once a season
bearing(use) lithium-lubrication). - 🔧 Check it out. tire-pressure (if the wheels are pneumatic).
- 🔧 Keep the wheeled boat in suspended Or on a flat surface (so as not to deform the transom).
For removable wheels:
- Take them off for the winter to avoid straining the screeds.
- Store in a dry place, pre-processed corrosion-proof (for example, WD-40).
If the wheels start to "eat" rubber or deform, this is a sign:
- ⚠️ Exceeding the maximum load (check the weight of the boat + engine + cargo).
- ⚠️ Wearing of bearings (replacement required).
- ⚠️ Incorrect adjustment of height (wheel touches the transom).
Regular inspection of wheels and mounts before each outing prevents 90% of the breakdowns associated with transportation.
Comparison of popular models of trans wheels for NDND

How to choose wheels for a motorized boat
For boats with an engine > 5 hp, wheels with a carrying capacity of at least 100 kg and reinforced bearings are recommended. Kender KW-15 or Yamaha Trolling Wheels Also check the bracket's compatibility with the transcuser - some motors require additional reinforcement.
FAQ: Frequent questions about transom wheels for PVC NDND
Can I install wheels on a boat with aluminum transceiver?
Yes, but with a mandatory anticorrosion Use stainless bolts (A4) and rubber pads. If the transom is thin (less than 3 mm), reinforce it with aluminum linings.
What wheel diameter to choose for the sandy coast?
For sand, the optimal diameter is 200–250 mmSmaller wheels will fail, larger wheels will be inconvenient to transport. flat-tyre (for example, Flinc TW-200).
What to do if the wheel starts to fall?
1. Check the tightening of the bolts (tighten if necessary).
2. Examine the sleeves and bearings - replace them with wear.
3. If the backlash is in the bracket, add rubber-stick between metal and PVC.
Can you make transom wheels yourself?
Yes, but only if you have experience with metal and PVC, homemade wheels are made from:
- 🔧 Bicycle wheels (diameter 20-24 inches).
- 🔧 Aluminum or steel brackets (at least 3 mm thick).
- 🔧 Bolts and stainless steel nuts.
However, factory models are more reliable - they take into account loads and have depreciation.
How to transport a boat with wheels by car?
1. secure the boat on the roof or in the trailer sling (at least 4 mounting points).
2. The wheels must be hard-fixedSo you don't hang around while you're moving.
3 If the wheels are removable, it is better to remove them during transportation.
4. The speed during transportation is not more than 90 km / h (to avoid vibrations).
