* Net horsepower and torque are measured on an MX360 production engine or prototype MX400 engine with the factory-installed air cleaner and muffler using Yamaha-developed test standards. Actual
power output of a particular engine can vary due to manufacturing tolerance differences, as well as numerous factors such as ambient operating conditions, how the engine is maintained, the type of
equipment being powered, and variances in the installation, including the intake and exhaust systems, fuel delivery, and engine cooling.
**Tentative data; subject to change with final production testing. All information herein is based upon prototype model.
***Fuel consumption estimates are based on Yamaha testing of an MX360 production engine or prototype MX400 engine with the factory installed air cleaner and muffler. Actual fuel consumption will
vary due to manufacturing tolerance differences, as well as numerous factors such as ambient operating conditions, how the engine is maintained, the type of equipment being powered, and variances in
the installation, including the intake and exhaust systems, fuel delivery, and engine cooling.
