The blue, red and black stripes on Yamaha outboard motors had long been symbols of the product and stood for the respective qualities of reliability, power and ease of use. They had also become a familiar and immediately recognizable icon of Yamaha outboards in waterside communities everywhere. That’s why there was naturally strong resistance from some when a sketch was presented for a new design using black, red, orange and gray arranged in a block pattern. The E40G and kerosene-compatible E40GK outboards were Yamaha’s first models to be developed specifically for commercial use. In anticipation of use in harsh environments around the world, engine performance was important, but the main focus was on excellent durability, reliability and serviceability. It was that kind of toughness that the designer wanted to express with the graphics of the new design. When these models with the new color scheme and graphics were sent to the various harsh use environments of markets in Africa, Asia, the Middle East, South America and the islands of the South Pacific, it was soon apparent how beautifully the new design fit into the scenery and how easily it became appreciated worldwide as a familiar part of the lives and livelihoods of the people and their industries. Distinctly different from pleasure-use models emphasizing speed, this new design marked the birth of a new line of rugged Yamaha outboard motors—the Enduro Series.
