Controlling the outboard motor with a standard gas handle is not always convenient – especially if you are standing on the bow of the boat, fishing from the stern or operating the vessel in a non-standard position. Gas handle extension So this solves this problem by allowing you to adjust the engine speed up to 1-2 meters from the transom, but how do you choose the right model, install it correctly, and avoid the typical errors?
In this article, we will take a look at all the nuances, from the design of extension cords to step-by-step installation instructions, you will learn which materials are more reliable (aluminum vs. stainless steel), how to avoid levitation And why cheap Chinese models can fail at the most inopportune moment. Why a cable-driven extender is categorically not suitable for electronically controlled throttle (ETC) motors.
Why you need a gas handle extension: 5 real situations
Many boat owners consider the gas extender an unnecessary luxury — until they face one of these problems:
- 🎣 Fishing from the stern: When you catch a spinning or feeder, and the motor is mounted on a transom, you have to constantly bend over or ask your partner to adjust the gas.
- 🏄 Control on the move: at speeds over 30 km / h standing at the transom is dangerous - the extension cord allows you to control the motor, sitting on the seat or standing closer to the nose.
- 🔧 Boat tuning: If you have installed additional equipment (echo sounder, radar), access to the gas handle may be blocked.
- 👨👩👧👦 Family travel: When children or passengers are on board without experience, it is better to control the engine yourself, without being distracted by moving around the boat.
- ⚓ Mooring: It is more convenient to approach the pier on low gas if the handle is at hand, and not a meter away from you.
The extension does not just add comfort, it securityAccording to GIMS, up to 15 percent of accidents on small craft are due to loss of control of the engine during a sharp maneuver or falling overboard, and with the extension extender, the risk of such situations is reduced significantly.
Types of Extension Couples: Which to Choose for Your Motor
All gas extension handles are divided into three main typesAnd a choice error can lead to engine failure or loss of control.
Mechanical (steering)
The most common and budget type, the way it works is that the cable in the shell transfers the force from the extension handle to the regular gas handle. carburetor and injector motors with mechanically driven throttle valve (for example, Yamaha 9.9 FMHS, Mercury 15 M).
Pros: Low price (from 1,500 ), easy installation, reliability with proper installation. Cons: over time, the cable stretches, can jam with inflections, requires regular lubrication.
2. Hydraulic
They use hydraulic fluid to transmit force, they are optimal for medium- and high-power motors (30 hp), where smooth gas adjustment is important. Teleflex SeaStar, Uflex.
Pros: There is no backlash, smooth running, long service life (5-7 years). Cons: high price (from 8000 RUB), the complexity of the installation (you need to pump the system), the risk of leaks.
3. Electronic
Connect to ECU They're powered by the engine and they're powered by the throttle, and they're only compatible with modern motors. ETC Electronic Throttle Control (Electronic Throttle Control) Suzuki DF140ATL, Honda BF150.
Pros: accuracy of adjustment, the possibility of integration with GPS- Autopilot. Cons: price from 15 000 RUB, requires professional installation, is vulnerable to moisture.
| Type of extension | Compatible motors | Average price, RUB | Complexity of installation |
|---|---|---|---|
| Mechanical (wiring) | Carburetor, injector without ETC | 1 500–4 000 | Low. |
| hydraulic | Injectors from 30 hp. | 8 000–20 000 | Medium |
| Electronic | With ETC (Suzuki, Honda, Yamaha) | 15 000–35 000 | High. |
⚠️ Attention: If your motor is equipped with a system ETCmechanical or hydraulic extension cord will disable himCheck the documentation: the presence of an electronic control connector is a sign of incompatibility with cable models.

Step-by-step instructions for installing a mechanical extension
You can install the cable extension cord yourself in 1-2 hours.
- 🔧 Set of screwdrivers (cross, flat)
- 🔨 Drill with drills Ø3-4 mm (if you need to fasten to a transom)
- 🛠 Keys for 8-10 mm
- 🧴 Silicone cable lubricant
- 📏 Roulette or ruler
Step 1: Dismantling the regular gas handle
Unscrew the screws of the handle attachment to the motor (usually 2-4 screws under the cross screwdriver). Carefully remove the handle without damaging the return spring. If the handle is fixed by the lock ring, use round-cutters.
Step 2: Installation of the adapter
Most extension cords come with an adapter that fits into the seat of the standard handle, and fasten it with screws from the kit, making sure that the cable hole matches the rotation axis.
Step 3. Laying the cable
Place the cable from the motor to the place where the extension handle is installed. Avoid sharp curves (radius at least 15 cm) and fasten the cable with plastic clamps to the transom or seat.
Step 4: Fixing the extension handle
Set the handle in a selected position (e.g., side console). Use screws or washer bolts. Adjust the length of the cable so that the handle is smooth, without delay.
Step 5: Setup and Testing
Check the extension cord at idle: the handle should smoothly return to its original position. If you detect backlash, pull the cable with a adjusting screw.
Check the cable attachment to the handle and motor | Make sure the cable is not twisted |Application silicone lubrication on the cable |Test the smoothness of the ride on land |Have a spare cable with you (if you are traveling far)->
⚠️ Attention: If after installation the engine stalls at idle speeds, the problem is cable-tighteningShorten it by 2-3 mm and repeat the test.
Tuning and improvements: how to improve the gas extender
Even factory extension cords can be modified for greater comfort, and here are some of the improvements we've tried.
Installation of the idling striker
Problem: the gas handle spontaneously shifts in the wave, the revolutions jump. lock-rotor Or a magnetic lock in the idle position, and an M4 screw with a lamb will do.
2. Protection of the cable against corrosion
The cable in the shell rusts over time, especially if the boat is kept outdoors. movillo or litholeAnd wrap the shell. shrink-tube.
3. Extension of the handle for sitting control
If you're driving a motor sitting down, the standard length of the extension handle (20-30 cm) can be uncomfortable. squirt Or stainless steel tubes.
4. Illumination of night fishing pen
Attach it to the pen. LED tape Or a Velcro LED flashlight, and you can use the backlight from the 12V onboard network or from the powerbank.
How to make a homemade extension cord from a bicycle cable
For a budget decision, take a bicycle brake cable (length 1.5 m), a lawnmower handle and an aluminum bracket. shelledOtherwise, it will cling to the parts of the boat, and the life of this extension extender is 1-2 seasons.
Frequent mistakes and how to avoid them
Incorrect installation or operation of the extension device may result in slippage Or engine failure. Here are the most common mistakes.
- 🔧 Twisted cable: leads to a difficult stroke of the handle and increased wear of the throttle mechanism.
- 💦 Lack of lubrication: The greaseless cable rusts and wedges. silicone lubricant (not litol!) so as not to attract dirt.
- 🔄 Sharp curves of the cable: The radius of the bend should be at least 15 cm, otherwise the shell will be rubbed.
- ⚡ Ignoring compatibility: The electronic extension cord on the carburetor motor will not only not work, but can also burn ECU.
- 🛠 Independent improvement of hydraulics: disassembly of the hydraulic extension cord without experience will lead to air entering the system and failure.
Another typical problem. pen-vibration It's usually a weak mount or a worn-out sleeve, so you tighten all the bolts and replace the plastic sleeves with bronze.
If the extension cord starts to bite in the cold, the problem is the thickened lubricant. frostproof silicone (for example, CRC Silicone) or temporarily move to WD-40 (But don’t forget to update it every 2-3 exits.)
Maintenance and care: extending the service life
To make the extension cord last longer, follow these recommendations:
-
After each launching:
Wash the cable with fresh water (if the boat was used in salt water). Rin the handle and mounts with a dry cloth.
-
Once a season:
Take the cable off, clean it of the old lubricant, and apply a new one. Check the shell for cracks.
-
Every 2 years:
Replace the cable and bushings (even if they look normal) and the kit costs from 500,, which is cheaper than engine repair.
-
Before winter storage:
Grease the cable preservative (for example, Liqui Moly MoS2) and store the extension cord in a dry place.
For hydraulic extension cords, add a paragraph: Once a year, pump the systemYou can do this yourself with a syringe and a hydraulic fluid. DOT 4.
⚠️ Attention: If the hydraulic extension cord starts to "fall down" (the handle goes too easily), this is a sign fluid leakageYou can't run it any further, you can risk losing control of the engine.
FAQ: Answers to Frequent Questions
Can I install an extension cord on an electronically controlled (ETC) motor?
No, mechanical and hydraulic extension cords are incompatible with ETCIt's a motor like that. plug-on (for example, Garelick Eez-In) which is connected to the normal electrical system.
How long should the extension cord be?
The optimal length is 1-1.5 m Longer cables (over 2 m) can sag and cling to the parts of the boat. For hydraulics, the maximum length is 3 m (thereafter lost efficiency).
Can I make the extension cord myself?
Yes, but only for mechanical motors, you'll need a wire rope in the shell (like a scooter), a lawn mower handle, an aluminum bracket and clamps, and you'll need to keep it running smoothly without backlash.
Why did the gas handle get tight?
The reasons may be:
- Tighten the cable, ease the tension.
- The lubricant dried - clean and lubricate the cable with silicone.
- Bending the bracket - align or replace.
- The cable is worn out - replace the cable completely.
Do I need to register the extension cord in GIMS?
No, the gas handle extension is not alteration of boat designBut if you modify the control system (e.g., installing an electronic autopilot), it's already a conversion, it needs expertise.
