Installation of steering on the PVC boat: from the selection of a set to test launch

Controlling a PVC boat with a steering wheel instead of a traditional humming wheel or remote control is not only a matter of comfort, but also safety. This is especially true for owners of boats from 3.5 meters in length, where the physical force on the tiller when maneuvering on the wave can become tedious, and the accuracy of the control is critical. However, installing steering requires not only tool skills, but also an understanding of the design features of your boat and motor.

In this article, we will discuss the whole process – from the choice steering-box (mechanical, hydraulic or electrical) before the final setup and testing. steering-wheel Or premature wear of parts, how to properly fasten the console to avoid vibrations, and why some PVC boat owners give up steering after the first trip.

1. Selection of steering type: mechanics vs hydraulics vs electrician

The first and most important step is to decide on the steering-styleIt's not just the cost of the kit, it's the complexity of the installation, the reliability and the sense of control, and let's look at three basic options:

• 🔧 Mechanical steering It's the simplest and most budget-friendly solution, suitable for boats up to 4.5 meters long with engines up to 50 hp, the main plus: minimal parts, easy installation and repair. Minus: requires physical effort when cornering, especially at high speeds.
• 💧 Hydraulic steering - optimal choice for boats from 4.5 meters and engines over 50 hp Hydraulics smooths the shocks of waves, reduces the steering effort and increases the accuracy of control. Cons: more expensive than mechanics, requires periodic maintenance (checking the level of fluid, tightness).
• ⚡ Electric steering or fly-by-wire) - a premium option for modern boats, minimal steering effort, possible integration with GPS and autopilot, cons: high price, dependence on electronics, complexity of installation.

For most owners of PVC boats of the middle class (3.5-5 meters) the best choice will be the best choice. hydraulicsIt balances price, reliability and comfort, and it's only about small boats with low-power engines that you can think of as mechanics, and it's about electrics if you're willing to pay for premium features.

When choosing, also take into account Compatibility with your motorFor example, for outboard motors. Yamaha or Mercury Often, special adapters are required to attach the steering thrust, so please check with the kit seller or the engine instructions.

2. Set of steering: what is included and how not to make a mistake with the choice

The standard steering kit for a PVC boat includes the following components:

Component	Appointment	What to pay attention to
Steering wheel.	Direction control	Diameter (usually 30-35 cm), material (plastic, aluminum), presence of motor control buttons
Steering column	Wheel fastening and force transfer	Adjustment height, material (stainless steel is preferred), console compatibility
Tractors and cables (or hydraulic hoses)	Transfer of force from column to motor	Length (should correspond to the distance from the console to the engine), protection against corrosion
Fortress elements	Column and thrust fixation	Quality of bolts and nuts (better stainless steel A4), the presence of rubber gaskets
Motor adapter	Traction coupling to engine tiller	Compatibility with the motor model (e.g., for Suzuki DF9.9 You need your adapter.

One of the key points is that thrustIf the thrusts are too short, the steering wheel will be heavy, and if it is too long, a backlash will appear. To calculate the optimal length, measure the distance from the steering column to the motor's mount in two positions: when the motor is turned left and right at the maximum angle. The minimum length of thrust should be 10-15% greater than the maximum measured distance to avoid tension when cornering.

When buying a kit, look at the brands. Among the proven manufacturers:

• 🏆 SeaStar Solutions (USA) – leader in hydraulic systems, reliability, but high price.
• 💰 Teleflex (now part) SeaStar) - good price/quality balance, mechanical kits are popular.
• 🛠️ Yamaha and Mercury Original sets for the engines of these brands, guaranteed compatibility.
• 🇷🇺 Domestic brands (Waterman, Flagship) budgetary decisions, but quality varies.

3. Boat preparation: where and how to fasten the steering console

Successful steering starts with choosing the right place to go. steering consoleMistakes at this stage can lead to boat imbalances, vibrations, or even damage to the PVC material.

• ⚖️ Boat balance: the console should be closer to the center of gravity. For most PVC boats, it's 1/3 of the nose. If you move the console too far forward, your nose will pick up; if you go back, the stern will slip.
• 📏 Distance to motor: optimally, if from the steering column to the engine is not more than 1.5-2 meters. The longer the thrust, the greater the backlash and lower the accuracy of the control.
• 🛠️ Fixing to a transom or cylinder: the console can be attached to the transom (if it is reinforced) or to the cylinder using special bracketThe second option is more reliable for boats without a hard transom.

To attach the console to the PVC boat are used:

• 🔩 Bolts with wide washers (at least 6-8 mm in diameter) and rubber gaskets so as not to damage the material.
• 🧲 Clay sealant (for example, Sikaflex 291 or 3M 5200) for additional fixation and sealing.
• 🛡️ Reinforcement plates from aluminum or stainless steel (thickness 2-3 mm), if the fastening goes to the transom.

How to check the strength of the console mount?

After installation, try to shake the console with your hands at a force of ~20 kg. If a backlash or PVC material has deformed, the mount should be strengthened, and check whether the boat does not sway when loading on the console (for example, if you lean on it).

If your boat is not on a hard floor (for example, keel or sling-floor), installation of the console becomes more difficult, in which case it is recommended:

1. Strengthen the place of attachment with an additional layer of PVC (stick the patch inside and outside).
2. Use it. folder on fast-removal mounts so that they can be dismantled during transportation.
3. Consider the option of steering-off (for example, Teleflex Safe-T QC), which is attached to a transom and does not require a full-fledged console.

Step-by-step instruction for the installation of the steering

Now, to the installation process itself, we're going to look at the universal circuitry for the mechanical system, because it's the most common circuitry, and for hydraulics, the steps are similar, but you add the fluid refilling and pumping step.

Make sure the boat is on a flat surface | Check the completeness of the steering | Prepare tools: drill, drill, keys, screwdrivers, sealant | Clear the place of attachment of the console from dirt and grease | Check the weather - installation in the rain is undesirable->

Step 1. Steering column fastening

1. Mark the console mounting locations on the boat using the level to check the vertical.
2. Drill holes in PVC material. The diameter of the drill should be 0.5-1 mm less than the diameter of the bolts.
3. Apply sealant over the holes and gaskets, then lock the console with bolts. Tighten the cross to avoid skewing.

Step 2: Installation of the steering wheel and column

1. Assemble the steering column according to the manufacturer's instructions, usually inserting the shaft into the body and locking with a locking ring.
2. Place the steering wheel on the shaft and attach it to the central nut, make sure the wheel rotates smoothly, without jamming.
3. Adjust the height of the column so that the steering wheel is at the level of your hands in a sitting position.

Step 3: Installation of traction and connection to the motor

1. Attach the thrusts to the steering column with hinge joints. Make sure they do not touch the cylinders or the floor of the boat.
2. Connect the second end of the thrust to the adapter on the engine tiller, which may require removing the engine casing.
3. Adjust the length of the thrust so that at the average steering position the engine looks strictly forward.

Step 4: Setup and Testing

1. Check the steering wheel in both directions - it should smoothly turn the engine to the maximum angle (usually 35-40 ° in each direction).
2. Make sure there is no backlash in the connections. The permissible backlash on the steering wheel is no more than 5-10 degrees.
3. Start the engine at idle speeds and check the steering. The steering wheel should return to neutral when released.

If you install hydraulic steeringAfter installation, you need to:

1. Refill the system with a special liquid (usually) Dexron II or SeaStar Hydraulic Fluid).
2. Pump the system, remove the air. To do this, turn the steering wheel from side to side 10-15 times, then add the liquid to the level.
3. Check the tightness of all connections - the dashing is unacceptable!

1. correctness of the thrust adjustment (they should not be stretched).

2. Status of lubrication in hinges (for mechanical systems).

Level of liquid (for hydraulics).

4. Coaxiality of the steering column and the motor (they must be parallel).

5. Common Mistakes and How to Avoid Them

Even experienced boatmen sometimes make mistakes when installing the steering, and here are the most common ones and ways to prevent them:

• ❌ Wrong traction length → It leads to tension or backlash.
  DecisionAlways measure the distance at maximum engine angles.
• ❌ Weak mounting of the console → The console wobbles or breaks off on the wave.
  Decision: Use reinforcing plates and a quality sealant.
• ❌ Ignoring the balance of the boat → The nose or feed is uprooted, controllability deteriorates.
  DecisionPlace the console closer to the center of gravity.
• ❌ Lack of lubrication in the hinges → The steering wheel creaks and spins tightly.
  Decision: Use a frost-resistant lubricant (for example, CRC Marine Grease).
• ❌ Improper hydraulic pumping → The air in the system leads to a "soft" steering wheel.
  DecisionPump the system at least 3-5 times until the bubbles disappear.

Another common problem is that steering The reasons may be as follows:

• Imbalance of propeller blades (check and balance the propeller).
• Wear of bearings in the steering column (replacement required).
• Insufficient rigidity of the console attachment (strengthen the design).

1. symmetrical thrusts (they must be of the same length).

2. the center of the motor (it must be strictly on the axis of the boat).

3. Pressure in the hydraulic system (in case of a malfunction of the pump, an imbalance may occur).->

Just as important is the right thing. steer after installation:

• 🔧 Mechanical systemOnce a season, check the backlash in the hinges and lubricate them.
• 💧 Hydraulic systemOnce in 2-3 seasons, change the liquid and check the tightness.
• ⚡ Electrical system: Keep track of the status of the wiring and contacts.

6. Test start and final setup

After installation of the steering control must be carried out test-launchTo make sure it's working and safe, here's a checklist to check:

Check the reliability of the console and all bolts | Make sure that the thrusts do not touch the cylinders or the floor |Control the steering wheel in both directions (should be smooth) | Start the engine on idles and check the reaction to steering |Check the steering wheel back to neutral position->

The first launching should be in calm (without strong winds and waves) Follow this algorithm.

1. Step back from the shore for 50-100 meters and check the reaction of the boat to steering turns at low speed.
2. Increase the speed to average and appreciate the steering wheel effort – it should be comfortable.
3. Perform a few sharp turns to check the reliability of the fasteners.
4. Check if there are any hydraulic fluid darts (for hydraulic systems).

If you notice the following problems, return to the shore immediately:

• 🚨 The steering wheel does not return to neutral position.
• 🚨 There was a strong backlash or knock in the steering column.
• 🚨 The engine does not respond to steering or turns with a delay.
• 🚨 Vibration that is transmitted to the steering wheel and hull of the boat.

1. Insufficient pressure in the hydraulic system (supply the liquid).

2. wear hinges in the mechanical system (replace traction).

3. Incorrect adjustment of the centering of the motor.->

After a successful test run, you can start finalization:

• Adjust the height of the steering column to your height.
• Set up the steering wheel force (for hydraulics this is done by adjusting the pressure valve).
• Make sure that all the buttons on the steering wheel (if any) are properly controlling the motor.

Steering maintenance and care

For the steering to last, it must be maintained regularly.

Type of system	What to check	Frequency
Mechanical	Luft in hinges, traction condition, lubrication	Before every season and after 50 hours of motorbike
hydraulic	Liquid level, tightness, pump operation	Every 100 hours or every 2 seasons
Electrical	Status of wiring, contacts, operation of sensors	Before the season and when mistakes occur

For mechanical:

• Make sure to use cold-resistant lubricants (for example, Liqui Moly Marine-Fett).
• Check for corrosion, replace them at the first sign of rust.
• Adjust the back of the steering wheel, tightening the nuts on the hinges.

For hydraulic systems:

• Use only the recommended liquid (usually) Dexron II/III or specialized marine liquids).
• When replacing the fluid, wash the system with fresh liquid to remove contaminants.
• Check the hoses for cracks and scuffs, replace them every 5 to 7 years.

For electrical:

• Watch the waterproof connectors. If water gets in, you can short circuit.
• Update the firmware of the control unit (if provided by the manufacturer).
• Check the voltage in the onboard network - drawdowns can lead to failures.

8. Alternative solutions: when steering is not necessary

Installing steering is not always a viable option, and in some cases, alternative ways of steering a boat can be simpler, cheaper and more practical.

• 🎯 Extension-coupled tiller It's suitable for small boats (up to 3.5 meters), allows you to control the engine while standing or sitting in any part of the boat. Pros: cheap, simple, no need for a console. Cons: requires physical effort.
• 📡 Remote control of the motor (for example, Teleflex Big T or Yamaha Remote ControlIt allows you to control gas and corners from the remote. Pros: compact, no need for a steering column. Cons: less accurate control, not suitable for high speeds.
• ⚓ Autopilot. - modern systems (e.g., Garmin Reactor or Simrad AP24) can steer without the steering wheel. Pros: comfort on long crossings. Cons: high price, dependence on electronics.

When to give up steering:

• If your boat is less than 3 meters, a ramper or extension cord will be more convenient.
• If you use the boat only for quiet fishing on the lake without current.
• If you have a limited budget and the boat is not designed for high-speed travel.

However, if you:

• Often walk long distances or along the river with the current.
• Use a boat for water sports (walkboarding, towing).
• You have a motor with a capacity of over 30 hp.

The steering will not be a luxury, but a necessity.

FAQ: Frequent questions about steering installation

Can I install steering on a PVC boat without a hard floor?

Yes, but it will require additional reinforcement measures.

• Use it. folder on quick-removal mounts.
• Strengthen the attachment site with additional layers of PVC and aluminum plates.
• Consider steering-out (for example, Teleflex Safe-T QC), which is attached to the transom.

Important: without a hard floor, the console should be as light as possible so as not to deform PVC.

Which sealant is best used to fasten the console?

For mounting the console to the PVC boat suitable for the following sealants:

• Sikaflex 291 - universal, elastic, resistant to vibrations.
• 3M 5200 - super-strong, but difficult to dismantle (suitable for permanent fastenings).
• Bostik MS Polymer - good adhesion to PVC, does not turn yellow with time.

Do not use silicone sealants – they are not strong enough for such a load.

What if the steering wheel is too tight after installation?

Possible causes and solutions:

• Wrong traction length → Shorten or lengthen the thrusts.
• Lack of lubrication in the hinges → Lubricate all movable joints.
• The nuts on the hinges are pulled. → Then, let them loose until they are out of the way.
• Low pressure in the hydraulic system → Pour the fluid and pump the system.
• Wear of bearings in the column → replace the bearings.

Can you install hydraulic steering yourself, or is it better to contact specialists?

You can install hydraulics yourself if you have:

• Experience with hydraulic systems (or willingness to follow instructions carefully)
• Special tool for pumping the system (pump, liquid tank).
• Time for setting up and testing (the first pumping can take 1-2 hours).

If you are in doubt, it is better to contact the service. Mistakes when installing hydraulics (for example, air entering the system) can lead to a failure of the steering wheel at the most inopportune time.

What diameter of steering wheel to choose for a PVC boat?

The steering wheel diameter depends on the size of the boat and personal preferences:

• 30cm It's optimal for boats up to 4 meters. It's compact, it doesn't take up much space.
• 33-35 cm - universal size for boats 4-5 meters. Convenient for long trips.
• 38 cm or more It's suitable for large boats (from 5 meters) or speed boats, and it gives you more leverage to control.

Also pay attention to the material of the steering wheel: aluminum light and durable, plastic - cheaper, but less durable.
