Operating a boat with an outboard motor often requires constant control of the engine, which requires the operator to be in close proximity to the transom. However, the standard length of the ramp does not always allow you to occupy a comfortable position, especially if the boat has a tent or awning that limits the space for maneuver. pulpIt becomes an indispensable accessory for improving the ergonomics of small-sized vessel management.
This tuning element allows you to shift the point of application of the operator's effort, providing a more convenient view and the ability to sit on the nose or central bank, rather than huddled at the side. This is especially true for long transitions, when your hands get tired of holding the handle of gas, or when trolling, when you need to control the spinning in your hands. extension handle It can change the feeling of driving a boat.
It is important to understand that the lengthening of the control lever changes the mechanics of interaction with the motor, requiring smoother movements to prevent sudden jerks of the bow of the vessel. In this article, we will discuss in detail the design features of various models, how they are reliably attached and the nuances that must be considered during installation, so as not to damage the engine rotation mechanism. Safety and reliability of mountings here come to the fore.
Design features and types of extension cords
The water-powered accessories market offers many options for redesigning a regular ramp, each with its own engineering solutions. The most common type is telescopic models that allow you to adjust the length of the departure depending on the current situation on the water. These devices usually consist of two pipes that fit into each other, with a lock that can be made in the form of a screw clip or a quick-release lever.
The second popular option is rigid nozzles of a certain length, which do not have the ability to adjust, but provide maximum rigidity of the structure without backlashes. Rigid extension cords They are often made of stainless steel or high-strength anodized aluminum, which guarantees a long life even in an aggressive salty environment. The choice between a telescope and a rigid bar depends on how often you need to change the control geometry.
Special attention should be paid to the versatile models with a flexible joint or hinge, which allows you to change the angle of inclination of the handle, which allows the operator to position the hand in the most natural position, reducing the load on the wrist.
- 🔩 Helical-fixed telescopic systems provide precise adjustment of length to the height of the operator.
- 🛡️ Monoblock rigid structures are characterized by maximum strength and absence of backlashes when driving.
- 🔄 The hinge joints allow you to change the angle of inclination of the handle for maximum comfort.
- 🌊 The materials of execution range from lightweight aluminum to heavy stainless steel.
⚠️ Note: When choosing a telescopic extension cord, make sure that the locking mechanism securely locks the tube. Spontaneous addition of the extension cord while driving at high speed can lead to loss of control of the boat.
Advantages of using an elongated rummel
The main reason boat owners decide to install additional equipment is to increase the comfort of the control. Standard romp often causes the operator to sit in an uncomfortable position, especially if the transom of the boat is located high or, conversely, low relative to the water level. Lever lengthening allows you to move away from the side, straighten your back and lean against the back of the seat, which is critical for many hours of fishing.
In addition to ergonomics, the extension cord solves the problem of compatibility with protective equipment. When installing a windshield or a full-fledged awning transformer, the standard handle can rest on the elements of the structure, preventing the engine from turning to a full angle or simply interfering with the passage. Shifting the control point forward frees up space in the cockpit, making movement on the boat safer.
And it's also worth noting that you can control your thrust more precisely when you're trolling, and when you're closer to the center of the boat, you can get a better sense of the boat's roll, and you can micro-move the course, which is harder to do when you're at the transom itself, where the pitching amplitude is highest. plug-in popular among fans of fishing on the track.
And the undeniable advantage is that you protect the operator from the spray that comes from the screw and the gearbox, and you stay dry even when you're excited, which is especially nice in cold weather, and it's a little thing that greatly enhances the pleasure of cruising.
Manufacture materials and strength requirements
Because the cord is subjected to constant dynamic loads, the material requirements are extremely high, and the main enemy of any metal structure on the water is corrosion, so manufacturers use special alloys. sea-aluminum (Series 5000 and 6000), which has high strength and excellent corrosion resistance.
Stainless steel is used less often because of its heavy weight, but in places of critical joints or in budget models, it is also possible to find it. It is important that all fastening elements - bolts, nuts, screws - are also made of stainless steel of the AISI 316 or AISI 304 brand. Using conventional ferrous metal will lead to rapid rusting and acidification of threaded joints, which will make dismantling impossible without a Bulgarian.
Plastic elements, such as handles or fixers, must be made of impact-resistant polymers that are resistant to ultraviolet radiation. Cheap plastic in the sun becomes brittle and can crack at the most inopportune moment, leaving you without control. composite It does not burn out and retains elasticity even after several seasons of operation.
To extend the life of the metallic parts of the extension cord, treat them regularly with silicone lubricant and rinse with fresh water after each release into salt water.
When buying, pay attention to the quality of welds or joints of pipes, they should not be cracked, sinks or traces of poor processing, any defective material under load can be a point of destruction of the structure.
Installation and installation instructions
The process of installing the extension cord usually does not require complex tools and special skills, but requires careful and consistent action. Most models are attached directly to the existing gas/reverse control handle. The first step is to dismantle the standard handle if the extension cord design involves replacing it, or prepare a place for docking.
If you use an overhead model, it's worn over a regular ramp, and it's important to make sure that the contact surfaces fit tightly, often with rubber seals or special gaskets that come with a kit that prevents the metal from squeaking and creaking against the metal. After you put it on, you need to tighten the locking bolts.
☑️ Checklist of extension unit installation
Special attention should be paid to the gas control cable. When installing the extension cable, the cable may tighten or, conversely, sag. You need to check that when you turn the tube to the extreme positions, the cable does not stretch to the string, but does not hang too loosely, otherwise you may have problems opening the throttle. Sometimes you need a slight adjustment of the length of the cable at the place of its attachment to the motor.
⚠️ Warning: After installation, be sure to check the stroke of the gas handle. It must return to neutral (idle) position automatically under the action of the spring. If the spring does not work due to friction in the extension cord, the operation of the motor is prohibited!
The final step is testing: fasten the motor to the transom (or use a stand), start the engine and check all modes of operation: neutral, front and rear, make sure that the extension cord does not touch the elements of the boat, clothing or awnings when the tube is fully moving.
Comparison of popular models and specifications
When choosing a particular product, you should focus not only on price, but also on technical specifications that affect durability and convenience. Below is a comparative table of the main parameters that you should pay attention to when buying.
| Parameter | Budgetary models | Mid-segment | Premium class |
|---|---|---|---|
| Materials | Aluminum (low-series alloy) | Aluminum (anodized) | Stainless Steel / Carbon |
| Type of fixation | Screw clip | quick-release lever | Double lock system |
| Adjustment of length | No or 1 provision | Telescope (2-3 positions) | Smooth telescopic |
| Weight. | Medium. | Optimal. | Minimum |
| Guarantee | 3-6 months | 1 year | 2-3 years |
Budget options often fail to meet the quality of edge processing and the reliability of the fixers; they may be suitable for rare trips to calm water; For active operation and access to large bodies of water, it is better to consider models of the medium and premium segment, where higher quality is used. bearing and seals.
The secret of longevity of compounds
In expensive models, inside a telescopic tube, a Teflon sleeve is often used, which reduces friction and prevents pipes from jamming into each other. In cheap analogues, metal contacts the metal, which eventually leads to bullies.
It is also worth considering compatibility with a particular brand of engine. Universal models are suitable for most brands, such as: Yamaha, Mercury, TohatsuBut for motors with electronic control or a specific shape of the handle, original adapters may be required.
Maintenance and maintenance of equipment
Any equipment operating in an aquatic environment requires regular maintenance. The cord extension is no exception. The main focus should be on mobile joints and threaded retainers. They must be disassembled periodically, cleaned of old lubrication, sand and salt deposits, and applied a new consistent lubricant.
If you notice that the telescopic part is getting tight or you're getting too much slack, that's a signal to maintain, and in the first case, lubrication will help, in the second case, replacing worn rubber seals or pulling up the adjusting screws, and ignoring these signs can lead to a jamming mechanism right on the water.
It is not recommended to store the extension cord assembled during the off-season unless it has been preserved, but it is better to disassemble it, wash it with fresh water, dry it and store it in a dry room, which will prevent the development of electrochemical corrosion in the contact areas of dissimilar metals.
Regular washing with fresh water and lubrication of moving parts is the guarantee that the cord extension cord will serve you more than one season without loss of functionality.
Visual inspection before each season will help to identify cracks or deformities in the early stages, and pay special attention to the places of attachment to the regular tiller, as this is where the maximum stress on the kink occurs.
Frequently Asked Questions (FAQ)
Will a universal extension cord fit a 5 hp motor?
Yes, most generic models are designed for a standard tube diameter, which is the same for motors of different power, but for low-power motors it is important not to overdo it with length, so as not to create an excess lever that can damage the gearshift mechanism.
Do I need to register the cord extension in GIMS?
No, the cord is considered an additional piece of equipment or accessory that does not alter the design specifications of the vessel or its power, so registration of these changes in the documents is not required.
Can I make an extension cord myself from a water pipe?
Theoretically, it can, but it's not safe: pipes (steel or plastic) are not designed for dynamic loads and vibrations; steel will quickly rust and plastic can burst; it's better to use specialized products made of marine aluminum.
Does the extension cord affect the engine warranty?
If the installation is done correctly, without damaging the normal units and the integrity of the control mechanisms, the warranty on the engine is maintained. However, if the reverse mechanism breaks due to improper installation of the extension cord, warranty repair may be refused.
How to remove backlash in a telescopic extension cord?
The backlash is usually eliminated by lifting the fixing screws or replacing worn rubber seal rings inside the pipe, and if the design permits, you can use adjusting sleeves.
