Driving a small vessel requires not only navigation skills, but also ergonomic arrangement of controls. The regular cranks installed by manufacturers are often fixed in length, which does not take into account the individual specifications of the boatmaster's build or the specific landing in a particular boat. pulp - a simple, but extremely effective accessory that can radically change the comfort of management.
This tuning element allows you to increase the lever of force, which is especially true for medium- and high-power motors, where the rotational force can be significant. In addition, increasing the length of the handle allows you to shift the grip point, freeing up space for the legs or allowing you to take a more comfortable position during a long transition. PVC Metal boats often face the need to adapt the standard equipment to their needs.
In this article, we will discuss in detail what types of extension cords exist, what materials they are made of and what to look for when buying. You will learn how to install correctly so as not to disrupt the emergency shutdown system, and whether to make this element yourself. A competent approach to modernizing the tiller group is a step towards safe and comfortable operation of your boat.
Why do you need an extension cord and what tasks it solves
The main function of the bumper extension is to change the geometry of the motor control. The regular handles are often short, which causes the operator to reach forward or bend, putting extra stress on the back. extensioner allows you to straighten your back and control the engine, resting on the elbow on the side or thigh, which reduces fatigue on long trips.
The second important aspect is safety, and when you're driving a powerful motor, for example, you can use it. Yamaha 30 or Tohatsu 18A long lever allows you to pull the motor off the back or to shift the steering wheel abruptly even with one hand without losing balance on the swaying bottom of the boat, which is critical in emergency situations when the count is seconds.
⚠️ Attention: Excessive lengthening of the rample without changing the gear ratio (for distance) or without taking into account the inertia of the motor can lead to too sharp turns. Be careful: a long lever increases the amplitude of movement, and an inexperienced driver can accidentally turn the boat 180 degrees at a sharp jerk.
Also, the lengthening of the bumper is often necessary for the installation of additional equipment, and it is convenient to put a trim control button, a tachometer or a mode switch on the elongated handle if the normal location of the controls is inconvenient, which turns the bumper into a full operator remote, where everything is at hand.
Manufacturing materials: aluminum, steel or plastic
The choice of material for the extension is always a trade-off between weight, strength and cost. There are three main options in the boating market and the range of homemade craftsmen, each with its own advantages and disadvantages that must be considered before buying or manufacturing.
The most common material is aluminum It combines high corrosion resistance, which is critical for fresh water and especially salt water, and low weight. Aluminum extension cords do not rust, are easy to process and look aesthetically pleasing. However, the softness of aluminum requires a greater thickness of the tube walls to avoid straining when compressed.
Stainless steel It's used less frequently, mainly for power elements or in low-end Chinese counterparts. Steel is stronger than aluminum, but much heavier. For a rummel that has to be operated constantly, the extra 300-500 grams at the end of the lever can become tangible, causing rapid fatigue of the hand. In addition, poor-quality steel can be subject to spot corrosion.
Plastic or composite extension cords are factory-made or expensive tuning, they don't conduct cold, they feel good, they don't corrosion, but when you hit them hard or twist them, they can crack, so you have to pay more attention to the quality of those products.
Compatibility with popular motor models
When choosing an extension, it is important to consider the design of your motor. Not all bumpers have a standard seat. Most modern two-stroke and four-stroke engines with a power output of 2 to 30 hp have a unified mounting assembly, but there are nuances.
The most easily tuning engines Tohatsu and Mercury (low power), as their rumples often have a simple tubular structure with an internal channel for the gas cable and emergency cable. Tohatsu 9.8 or 18 can be found in finished form or manufactured by selecting a pipe of the appropriate diameter.
Motors. Yamaha F and 2-strokes are also popular with anglers, and it's important not to overdo it with length, because the carburetor's damper can have a limited stroke, and if you set a lever too long, it can hit the transom or the body kit elements when you turn to the maximum angle.
For Chinese engines (Hidea, Sea-Pro, MikatsuOn the one hand, they often copy the design of Japanese analogues, which allows for the use of universal extension cords. On the other hand, the quality of the metal and assembly may be lower, so it is worth checking the reliability of the regular mounting of the tiller to the lower unit before installing any additional levers.
The secrets of compatibility of Chinese engines
Chinese manufacturers often change the design of the tube from batch to batch. Before buying an extension cord, be sure to measure the diameter of the landing tube of your engine with a rod, a difference of even 1 mm can make installation impossible or, conversely, lead to backlashes, which are dangerous on the water.
Instructions: how to install the extension cord yourself
If you decide not to buy a finished product, but to make a tiller extension for an outboard motor yourself, you will need to follow a certain sequence of actions. Homemade designs often outperform store designs in quality, as they are made "for themselves."
First, you need to remove the standard handle, which is usually attached to bolts or clamped with a clamping clamping, carefully remove it, trying not to damage the gas cable and the emergency switch wire (if it is built into the handle), often inside the tube of the tube, a cable passes, and it will need to lengthen or move the mounting point.
☑️ Checklist before the start of work
The main challenge is to control the gas. If your motor is controlled by turning the handle (gas in the handle), the extension cord must be tightly coupled to the throttle mechanism. This uses an additional cable or a rigid traction. If the gas is controlled by a separate handle on the tiller, the task is simpler - you just need to build the pipe.
The extension cord is best fitted to the regular tiller by a pipe-to-pipe method, with bolts through drilled holes. Be sure to use a grover or thread lock so that the vibration of the motor does not unwind the connections. After assembly, check the passage of the gas cable and the operation of the emergency switch.
⚠️ Attention: When self-manufactured, make sure that the extension cord does not block access to the candle hole or drain water from the cooling system. Also make sure that in extreme positions the pump does not touch the PVC tank with sharp edges, otherwise breaking the cylinder at full speed will become your main problem.
Gas and trim management
The lengthening of the bumper opens up new possibilities for ergonomics, but it raises the question of controlling additional functions. On the long handle, it is convenient to place the trime regulator (if the motor is equipped with electrohydraulics) and the mixture enrichment button.
To implement trime control on an elongated tiller, ready-made sets of buttons for outboard motors are often used, they are sealed and resistant to salt water. The wiring should be laid inside the extension pipe, if diameter permits, or along it, fixing with clamps and insulating with thermal shrinkage.
| Function | Method of implementation on the extension | Complexity |
|---|---|---|
| Gas (throttle) | Turning the handle or a separate trigger | High. |
| Trim (tilt) | Button switch (up/down) | Medium |
| Emergency stop | Button or magnetic switch | Low. |
| Tachometer | Installation of a digital sensor on the end | Medium |
Use it. sea-lubrication Water and electricity are a dangerous combination, especially when there's gasoline around.
To lay wires inside the metal pipe, use plastic corrugated or Cambrick, which will prevent the insulation from rubbing against the sharp edges of the metal when vibrating and will allow you to easily replace the wire if necessary without disassembling the entire structure.
Safety and Typical Errors in Tuning
The tuning of the tuber is not only about comfort, it's also about responsibility. An incorrectly installed extension cord can cause an accident. One of the most common mistakes is to disrupt the engine emergency shutdown system. The cable "cheeks" must have a sufficient range, but not sag, so as not to catch on to clothes.
Another common problem is backlash in the joints: if the extension cord hangs on the tiller, the control becomes inaccurate ("coat"). At high speeds, this can lead to loss of course or even folding the structure under load. All threaded connections must be tightened with force and fixed.
And balance is also important, because a too heavy extension cord at the end of a lightweight bumper can change the weight of the motor, putting too much strain on the lower unit or bracket, and this is especially true for short-leg motors, where the lever is already large.
⚠️ Attention: Never use wooden rods or undesigned metal bars to lengthen the rummel without a reliable attachment. The design must withstand a jerk force equal to several tens of kilograms, plus dynamic load from pitching and vibration.
Check the extension cord regularly. Metal gets tired, plastic gets old, mounts weaken. Every season, you do a check: rock the handle, check the cables, make sure there are no cracks. Your safety on the water depends on the reliability of each node.
The main principle of tuning the tube is the reliability of the mounting above all else, it is better to leave the standard length than risk losing control due to a broken homemade extension cord.
Frequently Asked Questions (FAQ)
Can I use a cord extension on remote-controlled motors?
No, on a rompel-gas and remote-control (steer-gas) engine, the tiller is used only to turn the motor, and the gas is controlled separately, and the extension of the romple is only possible for the convenience of turning, but the organization of gas control on it is not necessary, since the gas cables already go to the remote control.
How long can the rummel be as long as possible?
Optimal is considered to increase the length by 20-40 cm Further elongation makes the control uncomfortable due to the large amplitude of movements and can lead to deformation of the handle of the motor at the mounting site, since the load on the bending increases proportionally to the length of the lever.
Do I need to register the cord extension in GIMS?
No, the cord is considered a removable accessory or tuning element, which does not change the structural specifications of the vessel (length, load capacity, engine power) and does not affect buoyancy.
Where can I buy a ready-made extension cord?
Finished extension cords are less common than the motors themselves, and can be found in specialized boating stores, on marketplaces (AliExpress, eBay) for outboard motor tiller extension, or ordered from a turner to individual sizes.
