Yamaha F300 BETX Long Shaft Marine Engine with Outboard Starter

Powerful New Generation Units Produced by Yamaha. The launch of the Yamaha professional or special recreational F225 / F250 and F300 series has resulted in an excellent triple power combination. The latest Yamaha Marine technologies, advanced engine structure and intake/exhaust systems design, with micro-computer control, excellent fuel - air mixing and settings, increasing combustion efficiency,  it also provides convenience and savings during maintenance periods. Yamaha helps protect the environment by developing technologies that will provide "clean combustion" and never compromises on engine power.   When examined from a user's perspective, the most attractive aspect of these new models is that they can be compared in weight and size with a two-stroke engine in the same power class, it appears to be an incredible combination of lightness and compact design features.   At the very center of the engine is a 4.2-liter 60( V6 24-valve motor° 'closed loop' exhaust system with a )Top Dual Camshaft assembly. Again, in this excellent engineering concept, which Yamaha first introduced to the world, the classic layout of the intake and exhaust equipment is reversed and surprising savings in volume are achieved. These new engineering concepts, in addition to outstanding power, performance and acceleration, have enabled the production of three of the cleanest, smoothest and most complex outboard engine models that have ever come into contact with water. Behind these advantages, Yamaha's unique electronic fuel injection system ( includes a new 'long suction' system that increases torque at low and medium speed ranges), ECM with a microprocessor, there is combustion gas re-burning technology and special noise reduction systems. Along with durability, the level of reliability provided on water is probably the most sought-after features by Yamaha users around the world. In addition, the high-tech fault detection system developed by Yamaha for use in the latest outboard engines is one of the features integrated into these models. Thanks to the connection made with a personal computer via a simple plug-in connection, the usage and performance history of the engine can be examined on the screen, providing ease of maintenance and operation. In case of an unexpected problem, it is possible to start the engine at a low speed 'allowing access to the port with safety', thanks to a useful "fault-safe" system.

Outboard Engines:

Model: Common Specifications for Four Stroke F225 - F250 - F300 HP

Matters That Show Yamaha's Difference:A:

TCI (Mini Computer Aided) Ignition Systems: The FT50 is a standard feature available on every Yamaha starting with HP. Yamaha's TCI firing systems; They are monolithic parts that do not have moving elements. This feature plays an important role in ensuring that Yamaha outboard engines hold world-renowned records in the fields of easy starting, reliability and impeccable performance. In this way; In this way;

. A.Reliability and easy operation

. A.Strong, stable ignition feature at all speed levels

. A.Longer spark plug life thanks to the continuity of the ignition spark

. A.Its advantages, which can be listed as a maintenance-free system, emerge.

PrimeStartT: The "Automatic Choke" feature included in Yamaha's "PrimeStartT" application is the standard feature on many models. As easy as starting your car, it allows the driver to start a cold engine by simply turning the switch! The system eliminates the need for the classical choke system and automatically controls the 'warm-up' process. Therefore, there is no need to apply 'heating' by running the engine in a neutral position for a certain period of time.

High Output Alternators: It is available as a standard feature in many Yamaha models. Compared to the most popular competing models on the market, Yamaha engines use plenty of accessories to start the engine, even after the engine has been idled for a long time or when running at low revs, there is a high-output alternator that always has the necessary power.

Wide Range Hydraulic Download & Lift (PT&T) System: This is the standard feature on models in the series. Yamaha's monolithic, lightweight yet powerful PT&T (Power Trim & Tilt ) system is a technology envied by the Outboard engine industry. Provided with the classic button control mechanism, the quick controller adjusts the lowering and lifting angle quite conveniently and easily, and the trim angle range from -4° to +16°; driver, it ensures that it receives the best performance from its boat in all conditions. Negative trim adjustment enables speed increase in a short time and allows the boat to be brought to the (plane) minimum friction position more quickly.  

16-Supap DOHC Direct Moving Inline Type 4 - Stroke Engine: In this Yamaha engine, there are 2 intake and 2 exhaust valves on each cylinder, and the valves are moved independently by 2 camshafts. Thus, absorption and exhaust efficiency are increased and optimum combustion is ensured. Cylinder surfaces produced by plasma fusion technology are 60% harder than steel. This provides lower weight, better cooling and less friction. In conclusion; It means a larger cylinder volume and lighter engine.

Digital Electronic Remote Control: With the electronic data cable that is comfortable, fun and automatically synchronizes in double and triple engine mounts, with classic remote control wires fulfilled, the control of the engines in this model is both very enjoyable and easier. In dual and triple engine mounts, it is possible to start or stop all engines with a single button.

Multipurpose Digital (Numeric) Indicators: These digital indicators are available as standard accessories in this type of outboard engine models produced by Yamaha. These indicators are designed to provide optimum (en effective) visibility and can be used smoothly for a long time; It provides sensitive data that will help get the best performance and efficiency from the engine.

There are three different types of indicators:

. A.A "Multifunctional Speedometer" that includes engine speed (RPM), engine operating time, tilt angle, oil level and warning lights";

. A.A "Multifunctional Speedometer" that shows speed, distance traveled, time, fuel and battery voltage"

. A.And finally, a Fuel Control and Management Indicator that monitors fuel consumption and fuel economy".

SDS propellers (Vites Impact Damping System): SDS(Vites Damping System), which was first developed for the V8 and V6 models, reduces the "Clunk" sound between the tail gears during gear changes and enables smoother gear changes. A detachable rubber hub and fins on the propeller hub reduce sound and vibration, allowing for quieter and smoother gear shifting.

YAMAHA IMMOBILIZER SECURITY SYSTEM: Your engine is now safer with this system, which was first implemented by YAMAHA in the world. Once you lock your engine with the help of the remote control and leave it, your engine will be deterrent and safe from theft. With YAMAHA IMMOBILIZER SAFETY SYSTEM, the key to control is in your hands. Warning Systems Used for Engine Protection and Safety: In all Yamaha outboard engines, depending on the model, oil level, it has the feature of comprehensive monitoring of basic functions such as engine overheating or high speed. There are various warning devices installed on digital indicators to warn the user, such as lamps and an audible warning system. When an unexpected problem is encountered, the system reduces engine speed and ensures maximum protection of the engine as long as the malfunction continues. In this way, it is possible to take the boat/boat back to the beach without damage.

ECM (Motor Control Module) with Micro Computer: ECM is quite complex, in the case of the brain behind many functions, which makes Yamaha such a reliable and user-friendly outboard engine, it is an equally reliable microcomputer.   In fact, ECM monitors and controls a number of functions and features depending on the model, from setting the ignition time and checking the PrimeStartT function, it is responsible for all functions, from the introduction of many warning and protection systems that prevent damage to the engine and user. In reality, it forms a Yamaha's heart as well as its brain. All Four-Stroke EFI models F50 and higher and all HPDI and Vmax HPDI models, thanks to a simple connection with a laptop via a convenient access slot, instant fault detection can be made where the engine is located. This is real progress! . Monitors all data entries and setting locations without interruption, . It maintains smooth operation and trouble-free performance of the engine,

. A.Thanks to the advanced software, the ignition time setting is set to the most appropriate values in all operating conditions.

. A.Monitors and activates warning and protection systems.

. (diagnostik) provides computerized fault detection in the engine on all Four-Stroke EFI models at 50HP and above and on all HPDI models,

Propeller Models Rotating in the Opposite Direction: As it is known, in the standard mounted dual engine assembly (her two propellers rotate clockwise), the boat is always 'pulled' towards the port side and the steering becomes very difficult to control, especially at high speed stages. To solve this problem, Yamaha offers a counterclockwise rotating propeller assembly on high-power models. When this assembly is assembled together with a motor rotating in the standard direction, excellent 'neutral rudder' control is achieved.

Built with Sweet Water Washing System: Here's another user-friendly and practical idea discovered by Yamaha engineers! Just connect a garden hose to the easy-to-access fastener mounted on the front or side of the engine and remove any salt and other debris accumulated in the engine's water channels. It is obvious that this process will contribute to reducing possible corrosion and increasing engine life. And the engine does not even need to be started to implement this simple maintenance method.

In this way;

. A.Reduces corrosion and extends the life of the engine,

. A.It provides convenient, simple connection and easy operation,

. A.It enables internal washing without the need to start the engine or leave it running.

Yamaha's Ideal Protection Against Corrosioni: As a result of years of experience in Yamaha's extensive research, development and applications at sea, every Yamaha user now; it has the opportunity to enjoy the most effective and versatile coating and protection system advantages ever designed for an outboard engine. These are also valid for all types of marine engines.
