Yamaha F60FETL This four-stroke engine is designed for those who value reliability, low noise and economy, not wanting to put up with loss of power. Engineers at the Japanese corporation put into this model all the advanced technologies that made the brand. Yamaha synonymous with quality in the world of water-motor technology.
Special attention was paid to the ergonomics of control and ease of maintenance, as evidenced by the presence of an electric starter and an alternator. Owners of fast boats and heavy PVC inflatable boats will appreciate the traction specifications of this engine, allowing you to confidently glid even at full load. Below we will discuss in detail the design features, technical nuances and real performance of this popular unit.
Design features and design
Appearance of the engine F60FETL It immediately gives its belonging to a modern lineup. FourStrokeThe compact and streamlined casing not only protects the internal mechanisms from salt water and splashes, but also contributes to efficient heat removal. The use of lightweight aluminum alloys in the design of the lower unit and bracket has reduced the overall weight, while maintaining high strength and resistance to corrosion.
The cooling system is built on a closed circuit with forced circulation of off-shore water, which ensures a stable operating temperature even in maximum load mode. Oil Mist Lubrication (grease oil mist) significantly prolongs the life of the piston group, splashing oil directly into the crankcase.
⚠️ Warning: When you first start or after a long downtime, be sure to check the oil level in the crankcase, as the motor can come without the oil poured.
The design of the bumper is thought out to the smallest detail: the engine emergency stop button (stop button) is located so that it can be quickly pressed in a critical situation. The handle of the bumper has an anti-slip coating, and the gas fixing mechanism allows you to set the necessary revolutions for trolling or switching to glising.
Technical specifications of the Yamaha F60FETL
At the heart of the model is a four-stroke engine of 854 cubic centimeters with an upper camshaft (SOHC), which ensures excellent combustion of the fuel mixture and minimizes emissions. Maximum power of 60 horsepower is achieved at high revs, but torque is available in almost the entire range of operation.
Ignition system TCI Capacitor Discharge Ignition (CDI) ensures a confident start in any weather, whether it is hot summer or cool off-season. The 16-amper generator allows you to charge the battery while driving and power navigation devices, sonars or lighting equipment.
For clarity, we will give the main technical parameters in the table:

| Workload | 854 cm |
| Max. Power. | 60 hp (44.1 kW) |
| Launching system | Electrical starter |
| Weight (with screw) | 114 kg |
⚠️ Note: The specified weight is indicative and may vary slightly depending on the installed propeller and the length of the daydwoot.
Control and launch system
Modification with index L titled F60FETL This indicates a long leg (506 mm), which is ideal for transoms of standard keel boats and boats, and the launch system is implemented through an electric starter powered by a 12-volt battery, which saves the owner from having to pull the starter cord, which is especially valuable in cold weather or frequent launches.
The motor is controlled either through a ramper or through a remote rampel-gas (depending on the configuration and installation). To switch to the rampel control, it is enough to simply disconnect the remote cables, although this model most often uses a regular rampel. Forward-Neutral-Reverse (Forward-Neutral-Back) has a clear fixation and smooth stroke, excluding accidental switching.
The engine control unit constantly monitors the state of the systems and, if a malfunction occurs, activates an audible alarm. Indicators of overheating or drop in oil pressure light up on the panel, warning the operator to slow down or shut down the engine.

Performance and fuel consumption
One of the great advantages of four-stroke technology is that it's cost-effective, compared to two-stroke technology. Yamaha F60FETL It consumes significantly less gasoline, especially at cruising speeds, and the actual fuel consumption depends on a variety of factors: the weight of the boat, the condition of the bottom, the propeller chosen, and the driving style.
On average, when driving on a planing under full load, the flow rate is about 15-18 liters per hour. When you go to displacement mode or when trolling, this figure drops to 3-5 liters, which allows you to take long walks without refueling. AI-95 or AI-98 recommended for stable operation of the engine and prevention of detonation.
The quietness of the engine is another trump card, and the absence of the need to mix oil with gasoline and the presence of an effective silencer make the trip comfortable for communication, you can talk calmly to passengers without raising your voice, which is not possible on older two-stroke models.
How do you save fuel?
Keep the bottom clean — algae fouling can increase consumption by up to 20 percent, and it's also important to pick the right pitch for the propeller: too much stride will make the engine run in overload mode, and too little will not allow you to get on plane efficiently.
Maintenance and maintenance
Regular maintenance is the key to a long life for you. YamahaThe first service is usually done after running (the first 10 hours), then every 50 or 100 hours, depending on the regulations. The main procedures include replacing the engine oil, the oil filter and checking the spark plugs.
It is important to regularly inspect the condition of the lower unit for impacts and the presence of water in the gearbox. Lubrication of the slash joint of the paddle shaft should be made with a special lubrication with each change of oil in the gearbox. Do not neglect to replace the thin cleaning fuel filter, as the quality of fuel at different filling stations can be very boiling!
The cooling system requires attention in the form of regular freshwater flushing, especially after being operated in salt water, which will prevent scale and corrosion from forming inside the cooling shirt and thermostat. Thermostat is a critical element, and jamming can lead to serious overheating.
After each exit on salt water, be sure to wash the engine with fresh water. To do this, use a special nozzle on the "goose neck" and start the engine for a few minutes to wash the salt from the cooling system.
Selection of propeller
The right propeller choice has a direct impact on acceleration dynamics and top speed. The standard aluminum propeller that comes with the kit is chosen as an average option. However, for heavy boats or specific tasks (for example, water skiing or trolling), you may need to install a propeller with a different pitch or diameter.
If the engine does not reach the maximum recommended speeds (usually 5000-6000 rpm), then the pitch of the screw is too large. Conversely, if the engine roars, but the boat does not accelerate, the pitch of the screw is too small. Experiments with stainless steel screws can give an increase in efficiency, but they are more expensive and less repairable when hit.
When choosing, pay attention to the marking: the first digit is the diameter in inches, the second is the step. For example, the 11x13 screw has a diameter of 11 inches and a step of 13 inches. F60FETL The range of steps usually ranges from 9 to 15 inches depending on the load.
Frequently Asked Questions (FAQ)
What is the best oil to use in Yamaha F60FETL?
Manufacturer recommends using class motor oils FC or FD It is important that the oil is specifically designed for four-stroke outboard motors, as it contains additives that protect against corrosion in high humidity conditions.
What is the maximum speed of a boat with this engine?
The speed depends on the type of hull and weight of the vessel. For a light inflatable boat (about 300 kg with a crew), the speed can reach 40-45 km / h. For a heavier boat (500 + kg), the speed will be about 30-35 km / h. Accurate data can only be obtained empirically on a particular vessel.
Do I need to dilute the gasoline with oil for this engine?
No, absolutely not! Yamaha F60FETL It's a four-stroke engine with a separate oil lubrication system in the crankcase, and it puts pure unleaded gasoline in the tank, and mixing the oil with the gasoline will cause candles to coking, soak up, and possibly fail.
How to store the engine in winter?
To preserve, you need to drain all the fuel from the carburetor and tank (or use a stabilizer), replace the oil in the engine and gearbox, twist the candles and pour some oil into the cylinders, turning the crankshaft. Store the motor in an upright position in a dry room.
Why does the engine stop at idle speed?
The most common causes are a contaminated carburetor (idle jelly), an incorrectly exposed mix quality screw, air suction through the intake manifold, or a faulty ignition system (candles, coil).
The Yamaha F60FETL is an investment in comfort and reliability, and with proper maintenance, it can run thousands of hours of motorized driving while maintaining its traction performance and economy.
