4-Stroke outboard engines

Significantly Improved Fuel Economy During Cruising

TOKYO, Japan, March 6, 2008 – Honda Motor Co., Ltd. announced that it has implemented model changes for its BF50 (50HP) and BF40 (40HP) medium-sized, 4-stroke outboard engines. The new models will be available starting March 6 at Honda outboard engine dealers throughout Japan.

The new BF50 and BF40 outboard engines will retain their class-leading lightweight, compact packaging, enhanced with PGM-FI1 electronic fuel injection, Honda’s original BLAST2 (Boosted Low Speed Torque) air/fuel ratio and ignition-timing technology, and lean-burn control to deliver powerful startup and acceleration together with outstanding fuel economy during cruising.

BLAST, along with a newly designed gear case and other improvements, contributes to improved acceleration and a higher top speed, while lean-burn control results in a 22%3 improvement in fuel economy over the previous model4 during cruising. Battery charging capacity has also been increased to 17 amperes—over 1.7 times that of the previous model—to achieve class-topping5 charging performance.
