|Tokyo, February 8, 2002 --- Honda
Motor Co., Ltd. today introduced the new 4-stroke marine outboard motor BF175.
This extremely economical and reliable engine bolstered by Honda 4-stroke technology
achieves environmentally friendly performance that exceeds the world's strictest
emissions regulations established for 2008 by the California Air Resources Board
(CARB) in the U.S. The model will go on sale March 14 at dealers nationwide handling
BF175 was developed based on the 3.5-liter V-6 engine used in the Lagreat minivan.
Featuring Honda technologies such as Programmed Fuel Injection, the model maintains
smooth, even power output through the entire speed range. The low levels of vibration
and noise are further dampened by the addition of a large capacity intake silencer,
resulting in the quietest operating noise level in the class.
Styling for the BF175 takes advantage of the V-6 engine layout that strives for
an image of advanced technology and high functionality. This design also makes
the model easy to use in dual outboard configurations, and is in harmony with
a variety of boat designs.
The BF175 will be exhibited at the Tokyo International Boat Show and Osaka International

Major features of the BF175
- V-6, 3.5-liter, 4-stroke engine has achieved engine performance approximately
equal to that of a two-stroke engine.
- Excellent combustion
efficiency through programmed fuel injection and highly precise air-fuel ratio
control through an O2 feedback system, ensure improvements in fuel economy.
Good Environmental Performance <Honda e-SPEC product>
- In addition to exhaust
emissions that are well below the levels required by both the U.S. Environmental
Protection Agency (EPA) for 2006 and domestic Japanese voluntary controls, BF175
also exceeds the world's strictest emissions regulations established for 2008
by the California Air Resources Board (CARB).
- The V-6 configuration combined
with a large-capacity silencer ensures best-in-class quiet operation.
- A recyclability rate of 94% has been realized.(According to Honda measurement standards)
Lightweight & Compact
- The engine configuration has been designed
to realize a slim overall form, easily installable even on boats designed for
similarly classed two-strokes.
- The intake manifold and undercover made of
lightweight plastic contribute to an overall reduction in weight.
- A battery charger to which various accessories can be attached offers a
maximum capacity of 60A, the largest in the class. Over two times greater power
than others in the same class is available at low revs. (45A at 1,000 rpm)
- Counter-rotation spec. established, ensuring stability in the event that two units
are installed on a large-size boat.
