CDI/TCI Ignition Systems
Standard on every Yamaha.
Yamaha’s CDI and TCI ignition systems are ‘solid state’ components, with no moving parts. This plays an important role in creating the remarkable record of easy starting, reliability and faultless performance for which Yamaha outboards are well known around the world.
- Reliable and easy starting
- Strong, steady spark generation at all speeds
- Consistency of spark allows longer plug life
- Maintenance free system

Shallow Water Drive
Standard on most Yamaha models.
- Enables boat to be operated safely in shallow water
- Protects propeller and allows manoeuvring close inshore
|
|
|
Applies to:
F4A, F6A, F8C

High-output Alternators
Standard on most Yamaha models.
Compared with most competitive models, Yamaha engines have a high-output alternator to ensure that plenty of power is always available to start the engine, even after prolonged periods of idling, or using multiple accessories when running at low revs. |

Applies to:
F6A, F8C

Micro-computer ECM (Engine Control Module)
The ECM is a sophisticated micro-computer; the ‘brain’ behind many of the functions that make a Yamaha so reliable and user-friendly.
In fact, the ECM monitors and controls a variety of functions and features, depending on the model, and is responsible for everything from running the ignition timing and controlling PrimeStart™, to activating the many warning and protection systems that look after the engine and the user. In reality, it is almost the ‘heart’ of a Yamaha as well as the ‘brain’.
On all models from 50hp upwards, a simple hook-up to a laptop computer via the convenient access port, allows instant engine diagnosis, on the spot. Now that’s real progress!
- Constant monitoring of all data inputs and settings
- Maintains smooth running, trouble-free performance
- Advanced software optimises ignition timing in all conditions
- Monitors and activates warning and protection systems
- Computer engine diagnosis on all models 50hp and above

Fresh Water Flushing System
Standard on all models 6hp and above.
Another user-friendly and simple idea from the Yamaha engineers! Just connect a garden hose to the easy-access, front-mounted connector and flush away the salt and other dirt that accumulates in the engine waterways. Obviously it helps reduce any corrosion and extends the life of the engine still further. And there’s no need to even start the engine to carry out this simple maintenance procedure.
- Reduces corrosion and extends engine life
- Convenient, simple connection and operation
- Flush with no need to start or run the engine

Yamaha’s Ideal Anti-corrosion Protection
As a result of Yamaha's years of dedicated research, development and sheer on-the-water experience, every Yamaha owner can now enjoy the benefits of the most comprehensive and well-proven coating and protection system ever devised for an outboard. Or come to that, for a marine engine of any kind.
YDC-30
This unique anti-corrosion aluminium alloy, developed by Yamaha, has proven itself to be the most effective material for the protection of exterior engine components.
Self-sacrificing anodes
Large, but unobtrusive anodes are fitted in carefully calculated positions on engine casings, mounting brackets and lower units, and also inside the engine block and waterways of some models. The combination of high grade alloys from which these anodes are made, work together to ensure that the effects of saltwater are minimised and controlled as far as possible.
Special zinc coating
An additional zinc coating is applied to all non-moving stainless steel parts. This increases resistance to galvanic corrosion and acts as an anode back-up.
High quality stainless steel
Anti-corrosive stainless steel is used for many components such as drive and prop shafts, steering arms and through tubes.
5-Stage exterior coating
A build-up sequence of tough primers, undercoats and acrylic resin coatings are sealed in (but only after being oven-baked for ultimate adhesion and hardness) by the final coat of clear urethane lacquer which gives a Yamaha its unique lustre and long-lasting gloss finish. |

Start-in-gear’ Protection
‘Start-in-gear’ protection prevents the engine being started when Forward or Reverse is selected. On Manual Start models, setting any gear other than Neutral will cause the recoil starter to lock. On Electric Start versions, the power supply to the starter motor is isolated unless Neutral is selected. |

Applies to:
F6A, F8C

Warning Systems for engine protection and safety
Depending on the model, all Yamaha outboards feature comprehensive monitoring of major functions, such as oil level, engine overheat or over-rev. There are various warning devices fitted to alert the user, including cowling-mounted lamps, instrument lamps, and buzzers.
In the unlikely event of a problem, the system will automatically reduce the available engine rpm, providing maximum protection for the engine while the fault exists, and allowing the best opportunity to get the boat back to shore without damage. |

Yamaha’s 4-stroke technology – it’s the Number One difference!
A Yamaha 4-stroke seems to think it’s a 2-stroke! In recent years, our driving ambition in outboard design has been to combine the lightness and compactness of the incredibly reliable, high performance 2-strokes that made us so famous, with the superior economy, smoothness, sophistication and environment-friendliness of 4-stroke engine technology. The Yamaha Four Stroke line-up now offers the previously impossible: A complete range of 4-stroke engines, all comparable in weight and size to 2-stroke outboards in the same power class.
The key was YAMAHA innovation: look at our Four Stroke range and you’ll see technologies like CDI ignition, advanced EFI (Electronic Fuel Injection) systems, revolutionary engine layouts, ingenious intake and exhaust systems … even VCT (Variable Camshaft Timing); all with a ruthlessly efficient system of micro-computer control monitoring every aspect - from fuel mix - to combustion efficiency - to maintenance scheduling. It’s no accident that a Yamaha Four Stroke outboard holds the world record for fuel economy.
Above all, Yamaha’s 4-strokes succeed so admirably because from the very start, we never tried to adapt ordinary, everyday automotive engines, as most others have done. We built only pure marine-specification 4-stroke engines from scratch: every cubic centimetre, inside and out, designed with on-water performance in mind … and dedicated
to your on-water pleasure! |
