Yamaha’s two stroke 40HP engine is a shining example of what can be achieved from over 50 years of experience in designing and manufacturing top quality two stroke outboard engines. The E40JMHL is built around an extremely popular three cylinder configuration featuring loop charged fuel induction delivering heaps of grunt along with smooth and responsive operation throughout the RPM range.
Yamaha’s legendary three-cylinder two-stroke outboards are powerful, lightweight and compact. Excellent response throughout low and mid range RPM is achieved through superior exhaust manifold design and an ideal crankshaft arrangement
Superior manufacturing techniques allow a leaner oil mixture, reducing smoke, odour and engine carbon build-ups while also reducing oil consumption and running costs.
Yamaha’s unique marine alloy, YDC-30, has been developed exclusively to handle the harshest of marine environments and is the result of years of Yamaha research and testing.
Loop-charged scavenging creates a circular fuel flow for efficient transfer of exhaust gas and even distribution of the air-fuel mixture. The result is greater combustion efficiency for excellent performance and better fuel economy.
Maintenance Free CDI Ignition- The capacitor discharged ignition system provides strong spark and precise timing, preventing plug fouling, improving starting performance and reducing maintenance.
