Here are the 40HP outboards. With less than 1,000 cc, they deliver good speed and low consumption. Italian yachtsmen like 40HP outboards because most of them do not require a boating license. They are particularly appreciated by those who rent dayboats, for example. According to the current law, it is sufficient that they have a displacement of less than 1000 cc, if four-stroke, or 750 cc, if two-stroke. In any case, they offer interesting top speeds thanks to their reduced displacement.

The following is a selection of what the major manufacturers offer on the market today. Weight and other characteristics may vary depending on the selected shaft.

Suzuki DF 40 A ARI

It is named after the Chinese term “Ari” which means “ant”, the animal that manages to carry 30 times its weight. The thermal unit is derived from the more powerful DF60AV with which it shares the cubic volume, 941 cc, and the three-cylinder architecture. Compared to four-cylinder models, it is lighter and more compact.

Honda BF 40 D
