53 Development of Large V6 Four-stroke 225PS Outboard Motor 2002-32-1822

Since 1998, outboard motor manufactures are making every effort to meet the regulatory requirements that restrict the exhaust emissions from marine engines. Industry's first and the largest 4-sroke outboard motor F225A was introduced in the spring, 2001, targeting at off-shore fishing market in the U.S. This report describes technical features of 225HP V6 four-stroke outboard motor, which successfully conforms to the required limits, while maintaining the operating performance and compactness comparable to the corresponding two-stroke model, which has traditionally been in the mainstream of this marine engine segment.
