Finding a reliable and economical engine for a small inflatable boat often leads to one particular model. Yamaha 8 Enduro This is not just a marketing name, but the result of a deep modernization of the standard power unit for low load mode.
Decision Buying a Yamaha 8 Enduro outboard motor PVC boats are often accepted by owners of PVC boats with lengths from 320 to 390 cm. It is on such vessels that this engine reveals its potential, providing confident planing with one or two passengers. However, before buying it, it is important to understand the technical nuances that distinguish this version from the usual “eight”.
Unlike standard versions, the Enduro version is designed for long transitions at economical speeds. Fuel consumption This is a very low level, which is critical when fishing or traveling to remote locations, and then we'll go through all the aspects of operation, specifications and where you can buy this unit.
Why the Enduro version?
The main difference is the refined fuel mix system. Yamaha They changed the calibration of the carburetor and the ignition settings, which allows the engine to operate at low speeds, to keep it from deafening and to burn candles, which is a common problem with conventional engines in long-term trolling.
If you plan to use the boat mainly for fishing, where the speed of 10-12 km / h is the main, then the standard engine will work inefficient mode. Yamaha engine 8 Anduro It's not without these drawbacks, it keeps the craving even for the idle, allowing you to slowly catch promising areas of the reservoir without risking stalling.
⚠️ Warning: Do not try to reconfigure the carburetor of a conventional 8 hp engine yourself to Enduro mode without special equipment. This can lead to overheating of the piston group and engine failure.
In addition, this modification is often equipped with an elongated daydwoot, which makes it ideal for installation on high-sided boats or specialized boats. The reliability of the cooling system is also enhanced by optimizing ducts for partial load operation.
Technical specifications and features
When you look at the technical parameters, it's worth noting the two-stroke design of the engine. Despite the popular opinion about the gluttony of two-strokes, the Enduro version of this engine demonstrates amazing efficiency. Power 8 horsepower is achieved with optimal combustion of the mixture.
The engine weighs only 21.5 kg, making it easy to carry to one person and quickly set to a transom. The start system can be either manual (through the cable) or electric, depending on the specific configuration you choose when buying.
An important element is the CDI (electronic) ignition system, which provides a stable spark in all humidity conditions. Lubricant It is carried out through a mixture of gasoline and oil in a ratio of 50:1, which greatly simplifies the maintenance compared to four-stroke analogues.
| Parameter | Meaning |
|---|---|
| Type of engine | two-stroke |
| Power | 8 hp (5.9 kW) |
| Workload | 184 cubic centimetres |
| Weight. | 21.5 kg |
| Recommended fuel | AI-92 + butter 2T |
Fuel consumption and economy
One of the main questions that arises when a user decides to Buying a Yamaha 8 Enduro outboard motor In trolling mode (about 3000 rpm), the flow rate is approximately 1.5 to 2 liters per hour, a record for engines of this class.
When you go full planing, the consumption increases to 3-3.5 liters, but in this mode, Enduro engines are rarely used. The main element is a moderate course, where the fuel economy reaches 20-30% compared to standard models without the Enduro console.
Use only quality two-stroke oil labeled TC-W3. Cheap oils can quickly coke exhaust windows and reduce engine power.
To calculate the range, you can use a simple formula: divide the tank volume by the average flow rate. With a 12-liter tank, you can walk more than 100 kilometers in economical mode, which covers the needs of most fishermen and tourists.
Compatibility with PVC boats
The choice of the boat directly affects the efficiency of the motor. Yamaha 8 Enduro It is perfectly combined with PVC boats with lengths from 3.2 to 3.9 meters. On three-meter boats it will provide confident plane with one person, and on four-meter boats it will provide comfortable movement of two.
It is important to consider the boat's load capacity and the height of the transom. If the transom is too low, the motor will capture water; if it is high, cavitation will occur. The optimal height of the installation is 381 mm (15 inches) from the top cut of the lower unit to the anti-cavitation stove.
⚠️ Attention: Installing an 8 hp engine on boats less than 2.8 meters in length is prohibited by safety regulations and can lead to a boat tipping over due to too sharp a set of speed and lack of buoyancy margin on the nose.
Also, consider the weight of the engine relative to the load capacity of the boat. For light inflatable models, every kilogram counts, but 21.5 kg is quite a lifting weight that does not reduce the payload critically.
Where to buy and what to pay attention to
Deciding where Buying a Yamaha 8 Enduro outboard motorThe market is full of offers, but the risk of running into counterfeit or “gray” imports without support remains high.
Official dealers provide a complete package of documents, including a warranty card and a user manual in Russian, and they often offer pre-sales preparation services (break-in on the stand), which saves you from the initial fuss with settings.
☑️ Checking when buying a motor
When buying from hand or in the secondary market, be sure to check the compression. The normal value for a used motor should not be lower than 9-10 atmospheres. Also check the lower unit for deep scratches that could disrupt the cooling system.
Service and preparation for the season
The durability of the engine depends on proper maintenance. Before the season, you need to check the condition of the spark plug, clean the fuel filter and lubricate all movable connections. Adjustment of the carburetor It is rarely required, but idling is mandatory.
The new engine takes about 10 hours to run, and it is not recommended to give full gas at this time. The mixture should be slightly richer than usual, so more oil is added to the tank (a ratio of 1:25 instead of 1:50), unless the manufacturer has indicated otherwise in the instructions for a particular batch.
To store the engine in the winter, you need to conserve: drain water from the cooling system, treat the inner cavities with anticort and store it upright, which will prevent corrosion and cracking of the osteoils.
The Secret of Long Service to lower unit
After each trip in salt water, be sure to rinse the engine with fresh water. The salt crystallizes in narrow cooling channels and causes rapid overheating, even if the motor looks clean visually.
Don't forget to change the fuel filters. In our country, the quality of gasoline can vary, and the fine mesh in the tank or carburetor quickly gets clogged with dirt, causing engine outages at high revs.
Comparison with competitors
There are similar offers from Tohatsu, Suzuki and Chinese manufacturers on the market. Yamaha 8 Enduro It's also known for its maintainability and availability of parts, even in remote areas, and it's easier to find parts for Yamaha than for many of its competitors.
Chinese engines win in price but often lose in casting and assembly accuracy. Tohatsu engines are similar in performance, but Yamaha's Enduro version has a more streamlined system for working on poor mixtures, as evidenced by many years of experience in operation.
Yamaha 8 Enduro is an investment in reliability. The overpayment for the brand pays off with no problems launching in cold weather and stable operation for years.
The choice should not only consider the price of hardware, but also the cost of ownership. Fuel consumption and resource before major repairs in the original Yamaha, as a rule, higher than the budget counterparts.
Do I need to register the 8 hp engine in GIMS?
Under current Russian law, small vessels with a motor of more than 8 hp (5.88 kW) are subject to registration. Since the power of the Yamaha 8 Enduro is exactly 8 hp (or slightly less in kW), formal registration is not required. However, the engine documents (check, PCM) should always be with you to confirm the power during inspection.
Can this motor be used in shallow water?
Yes, but with caution. The engine is standard lower unit length. For very shallow waters, there are models with a short lower unit or a lift system (Tilt), but a standard Yamaha 8 requires a depth of at least 30-40 cm to safely draw water without capturing sand.
Which oil is better to put in the mixture?
Use only oils labeled TC-W3. The best choice will be the original Yamaha 2M or 2WC oils. They provide the best lubrication and minimal smoke, which is important for a two-stroke engine.
What to do if the engine does not start?
Check for sparks, candle condition and fuel supply. Often the problem is with a clogged carburetor jet lacquer or old gasoline. Also make sure the fuel crane is open and the pump pear is properly connected.
