Honda - BF20

It all started with a desire to
keep our air and water clean
In the age before Honda developed the now
mainstream 4-stroke outboard engines, many
people thought that it was virtually impossible
from a technical standpoint to develop a 4-stroke
outboard engine. Honda enthusiastically took on
this challenge. The history of 4-stroke outboard
engines can be told with the outboard engines
developed by Honda. Since outboards are used
in the great outdoors the thing that we are most
proud of is our steadfast commitment to the
concept of 'foremost concern for the environment.'
We have followed this principle since outboard
development started in the 1960s. The result is
clean water and fresh air. Honda will continue
to take on this challenge with useful innovative
concepts and unique technology, guaranteeing
nature will be preserved for future generations.
