The comfort and safety of movement on the water directly depend on the quality of the navigation vehicle. boat-stand It's not just a tuning element, it's a critically important outboard motor, and without that mechanism, manually controlling a heavy propeller becomes a grueling water fight, especially when there's wind or current.
The modern market offers many options for consoles adapted to the specifics of the soft side, but it is important to understand that there are no universal solutions. Construction Your boat, the type of boat used transom-holding And the power of the motor dictates the choice of equipment, and the wrong selection can lead to damage to cylinders or even loss of control on the go.
In this article, we will discuss in detail how to choose the optimal model, which materials are preferable for harsh operating conditions and how to properly mount the system so that it lasts for years. The critical parameter is the height of the rack relative to the lower unit of the engine, since an error here will lead to air sucking or, conversely, to overheating of the engine due to insufficient water intake.
Purpose and arrangement of the steering rack
The main task of the steering rack is to transform the rotational motion of the bumple into a convenient angular movement of the steering wheel mounted on the rigid console. pulp The outboard motor requires a lot of effort to turn the lower unit, which creates a lot of resistance. gearbox Or a cable system, allows you to control the boat with one finger, regardless of speed and load.
Structurally, the product is a vertical pipe or profile, on the upper end of which the steering wheel is fixed, and inside or outside the thrust of the control passes. The lower part is equipped with a fastening assembly, which is fixed on a transom or a special bracket. slip-bearing and tightness of the thrust entry determine the smoothness of the course and durability of the node in an aggressive aqueous environment.
⚠️ Note: When buying, pay attention to the presence of lubricated nodes. Cheap models often come with closed bearings that cannot be serviced, leading to corrosion and jamming after the first season.
An important element is also the cable cable, which connects the rack mechanism with the rotary mechanism of the motor, which should have high tensile strength and tensile resistance. Stainless steel or special aluminum alloys are the main materials used in the production of high-quality racks, as they are not afraid of salt water and ultraphylete.
Criteria for selection: materials and construction
Choosing. steering-post, first of all, look at the fabrication material. Aluminum alloys with anode coating are lightweight and do not rust, but can deform when hit hard. Stainless steel is stronger but much heavier, which can be critical for lightweight inflatable boats with low load capacity. Plastic elements are only permissible as decorative casings, but not load-bearing structures.
The geometry of the rack should be the size of the cockpit. A console that is too tall can block the view or interfere with movement, and a low console can create inconvenience when driving. The optimal height is selected individually based on the height of the boatmaster and the location of the seats. Also important is the diameter of the mounting of the helm, which is standardized, but it is better to check compatibility with your model. steering-stage.
Let’s look at the main types of constructions:
- 🛶 Monoblobular racks: whole pipe with welded flange, are highly rigid, but difficult to transport.
- ⚙️ Prefabricated models: consist of several sections connected by threads or bolts, convenient for storage in a bag-packaging.
- 🔧 Universal brackets: allow you to adjust the departure and angle of inclination, suitable for boats with complex transom geometry.
If you plan to fish with a sonar, choose racks with the ability to attach additional equipment or brackets for sensors.
You don't have to skimp on the quality of the cable pair. Cheap wires in plastic braids quickly lose their elasticity in the cold and can crack, and you'd better choose products with a metal braid or a quality polymer that retains its properties at low temperatures. luft in the connections of the cable is unacceptable, since it leads to a delay in the reaction of the boat to the turn of the helm.
Compatibility with PVC boats and transboards
The steering of an inflatable boat has its own specifications related to the softness of the transom. Direct attachment of the rack to the transom board through a PVC cylinder is often impossible or inefficient due to the deformation of the material under load. cross-plate or rigid brackets that distribute the load.
A trans plate is a rigid plate (often made of aluminum or coated plywood) that is attached to the trunk of the boat and is already mounted to the steering rack and motor. This design allows you to withstand considerable effort when maneuvering. It is important that the stove has sufficient support area and reliable attachment points to the sides and bottom of the boat.
| Type of boat | Recommended type of attachment | Max, engine power. | Features |
|---|---|---|---|
| Rowing (up to 3.2 m) | Removable bracket on the transom | up to 5 hp | Minimum weight, simple installation |
| Motor-racing | Trans plate (aluminum) | 15 hp. | Hard fixation, PVC protection |
| Fully-fledged motor | Reinforced slab with a roumpel post | 30 hp. | For permanent use with steering wheel |
| Hard-bottomed boat | Integrated console | up to 50 hp | Maximum comfort and review |
When choosing compatible equipment, consider the type of inflatable keel. If the keel is inflatable (NDND), the vibration from the engine is transmitted differently than on slurry boats. Amortizing gaskets between the transom plate and the balloon are required to prevent rubbing of PVC fabric.
Can I install a steering rack on a boat without a transom stove?
Theoretically, you can use clamps around the cylinder, but it's extremely risky. At high speeds, the balloon deforms, and the control becomes unpredictable, and there's a high risk of damaging the material.
Instructions for the installation of the steering system
Installation of the steering rack requires accuracy and adherence to technology. Mistakes at this stage can lead to loss of sealing of the boat or failure of control. Before starting work, make sure that all components are available and the surface of the transom is cleaned and defatted.
The installation process is as follows:
- Mark the mounting points of the transom plate or bracket. The center of the thrust hole must strictly coincide with the axis of rotation of the motor.
- Install shock absorbing gaskets made of rubber or neoprene between the stove and the transom.
- Secure the plate with bolts, using washers of increased diameter to distribute pressure on PVC.
- Mount it. steering-post on the stove, checking the verticality of the installation.
- Strip the cable traction from the rack to the motor, avoiding sharp corners and bends.
☑️ Checklist before launching
Pay special attention to the laying of the cable, it should not rub against the sharp edges of metal or PVC. hub The tension of the cable is regulated by special nuts at the ends; it must be such that it does not create excessive resistance.
⚠️ Warning: When drilling holes in the transom plate, use only metal drills and be sure to remove the burrs. Sharp edges can damage the cable or boat cylinder when vibrating.
Maintenance and care of the mechanism
The longevity of the steering is not only dependent on the quality of the materials, but also on the regularity of maintenance, and after each release to salt water, the system must be washed with fresh water to wash away the residue of salt, which is the main enemy of the metal. stainless steel It can be subject to point corrosion in an aggressive environment.
For marine applications, only special lubricants that are not washed away with water (e.g., lithium-based or special sprays) are suitable. The lubricant should be applied to the entry points of the cable and to the steering wheel bearings at least once a season or after long downtime.
Check the condition of the cable traction regularly. Signs of wear are:
- 🔍 The appearance of rust on visible sections of the cable.
- 🛑 Difficulty moving or jamming when turning the steering wheel.
- 📉 The appearance of backlash, which cannot be eliminated by adjustment.
- 🧵 Damage to the outer braid of the cable.
Timely replacement of worn-out cable is much cheaper than engine repair or rescue operation due to failure of control at full speed.
If you find that the steering wheel has become tight, do not use force. Take the mechanism apart, clean the old lubricant and dirt, and replace the damaged elements. Keep the boat with the installed rack is better disassembled or under the cover to protect the mechanism from dust and moisture.
Frequently Asked Questions (FAQ)
Can I install a steering rack on a motorized boat up to 5 hp?
Technically, it's possible, but economically and practically impractical: motors of this power are lightweight and short lower unit, manually operating them does not require much effort, and mounting a rack will increase the weight on the transom and reduce the speed of the boat due to aerodynamic drag.
How long should the steering cable be?
The length of the cable is selected individually depending on the distance between the steering wheel and the engine. Standard sets are often 3 meters long, which is suitable for most boats up to 4.5 meters long. For longer vessels or for complex laying (with rounds), order a longer cable or use an extension cord.
Do I need to remove the steering rack when transporting a boat?
If the rack is removable and does not interfere with the packaging, it can be left, but if you use a soft boat case, the protruding parts of the rack can damage the PVC when compressed, it is better to dismantle the steering wheel and the top of the rack, if the design allows.
Why is the steering cable breaking?
The main reasons: corrosion of the inner veins due to moisture entering the braid, rubbing on sharp edges, sharp jerks during maneuvering or improper adjustment of tension (too tight course).
Is the steering rack compatible with electric motors?
Yes, most universal racks are suitable for rumpling electric motors, but since electric motors are usually lighter than gasoline ones, make sure the transom stove can withstand the weight of the rack and steering wheel without disturbing the boat's balance.
