Если обороты двигателя превышают
рекомендуемые, замените гребной винт на модель с большим шагом.

Если обороты двигателя ниже рекомендуемых, замените гребной винт
на модель с меньшим шагом.

ПРИМЕЧАНИЕ

Не допускайте продолжительной работы
двигателя на оборотах, превышающих рекомендуе-мые – это может привести к повреждению двигателя.

0*Изменение
шага гребного винта на 25 мм приведет к изменению оборотов двигателя на 200 об/ мин.

Кроме того, изменение оборотов зависит от типа
винта, воды (соленой/пресной), типа судна (мас-сы и формы корпуса) и т. д.

0*При подъеме мотора с помощью системы гидроподъема
максимальные обороты двигателя увели-чатся.

Yamaha outboard motors are different from the remaining unmatched reliability, exceptional quality, remarkable fuel economy, and ease of compact design art.

Yamaha Motor Co., Ltd. has been manufacturing outboard motors since 1960. The first-born company was the 123-cube «R-7». In the same year, the plastic boat «SAT-21» appeared on the market.
Starting literally with the release of the first outboard motor, the leadership of Yamaha Motor Co., Ltd. began to pursue a very aggressive sales policy, actively capturing the markets of the
United States, Canada, Europe and Asia. Australia did not escape this fate, as, indeed, other countries and even continents. Today, Yamaha Motor Co., Ltd. products will be sold both under their
own logo and under other brands.

The active development of the market for motorcycles, jet skis, snowmobiles, ATVs and other power equipment is forcing many manufacturers to improve various production technologies and improve
product quality. One of the first «Yamaha Motor Co., Ltd.» began to use on a 2-stroke outboard motors separate lubrication system, which was called «Autolube». More sophisticated technologies on
2-stroke engines began to be used in the 90s of the last century and made it possible to keep powerful models in the production program that meet the environmental standards of many countries and
even surpass them. HPDI technology, which is equipped with high-power injected 2-stroke engines, implies the presence of a fuel injection system in the combustion chamber under high pressure, due
to which the fuel-air mixture burns almost completely. This allows not only to reduce harmful emissions into the atmosphere, but also to increase the efficiency of the motors themselves, as well
as to reduce the specific fuel consumption.

By 2000, Yamaha Motor Co., Ltd. produced 6 million outboard motors, which spread throughout the world.

If today we ask the owners of boats and boats in various parts of the world, whatever motor they wanted to buy for their boat,
then the Yamaha engines will be the first in the rating, so firmly established in their minds is the image of Yamaha Motor Co., Ltd. implies high quality and good consumer opportunities.
