The begining of the awesome Yamaha F200/225/250 series was acknowledged as a landmark in outboard history; the introduction of the most powerful and technically advanced four-strokes ever produced. Since they are now widely regarded also as the most impressive and stylishly designed engines ever to grace the stern of a boat, one thing is certain; this is the ultimate outboard experience.So extensive are the revolutionary technical features and innovations pioneered by Yamaha with these remarkable engines, that what goes on under the cowling can be described here in only the broadest terms. Suffice it to say that it involves Yamaha’s development of a new four-stroke format that turned conventional thinking on its head by creating an engine with an ‘in-bank’ exhaust system. A world first for Yamaha, this outstanding engineering concept reverses the conventional layout of the intake and exhaust systems, providing astonishing compactness.
In addition to their phenomenal power, performance and acceleration, these engines are three of the cleanest, quietest, smoothest and most sophisticated ever to hit the water thanks to, among other things, a unique EFI system, a micro-processor ECU, VCT (Variable Camshaft Timing), blow-by gas re-burning technology, and special noise reduction systems.
On-water reliability, in combination with durability, are probably the features most appreciated by Yamaha owners around the world, so our sophisticated diagnosis system is also a feature of these models; a simple plug-in link to a personal computer displays a running history of engine use and performance, making easy work of maintenance and servicing.
