Description

The 6LY3-STP is rated at 440HP (324kW) and the 6LY3-UTP is 380HP (279kW), both at 3,300rpm and measured under conditions defined by ISO 8665 conditions.

Ultra-smooth LY3 Series engines, lightest in their class, incorporate sophisticated electronic control to ensure constant power, almost regardless of operating conditions. They are turbocharged, inter-cooled and waste-gated six-cylinder power plants, with a wide choice of marine gear. Yanmar has become the benchmark for power-to-weight superiority and the tough, direct-injection LY3 Series extends the innovative technology to push performance still further.
