Used marine engine Yanmar 6AYM-WET 829HP for sale

Description

Built for the long haul on commercial fishing trawlers and ferries in the 25–35m range, the Yanmar 6AYM-WET delivers 829HP at 1,900 RPM — enough grunt for working vessels that run hard every day without babying the throttle

Fuel draw runs around 225–250 L/h at full load, which is competitive for a 20.4L turbocharged diesel at this power class — you're not paying premium for fuel you didn't burn.

Yanmar built the AYM series for non-stop commercial operation, and these engines routinely hit 40,000–50,000 hours before a major overhaul when cooling lines are kept clean and injectors serviced on schedule.
