It wasn’t until a year after the introduction of the P-7, that Yamaha outboard engines began to be recognized and accepted on the market with the release of the second model, the P-3. The P-3 was developed and refined based on feedback directly from the market. It had been developed precisely for the needs of the growing commercial-use market, where 3 hp engines were the de facto standard. Having been developed with a focus on engine durability and corrosion resistance, the P-3 was especially resistant to abrasion.
This was thanks to the exclusively developed aluminum alloy is used, which contained silicon. It was also the first domestic outboard engine to use die-cast parts, helping achieve a lighter and more compact design. Special attention was also given to making the engine easy to start and operate. The fuel tank of the P-3 was designed by female staff members, which was unusual in those days but met one of Yamaha’s shared values: innovation.
At that time, red outboard engines were quite popular and the coastal waters were truly a sea of red. One year after the launch of the P-3, however, waters off saw a conspicuous increase in “yellow hats,” as Yamaha outboard engines soundly infiltrated Japan’s coasts.
The engine was powered by a 63cc air-cooled single-cylinder 3 hp engine. It was made of aluminum alloy which contained silicon.
