Introduction
LY3 Series (Shaftdrive)

Yanmar LY3 Series Marine Diesel Engine
(380 - 480hp)
Advanced electronic control provides constant power governing, regardless of fuel temperature up to 50°C, and a multi-engine synchronization feature allows for one-level operation.

Information from the electronic control system is shown on a new Yanmar multi-function LCD display at the helm. Yanmar's multi-function LCD display shows critical engine data received from the electronic control system via a CAN-BUS Network. The captain is provided with real-time engine data, including engine speed, trip duration, battery voltage, coolant temperature, fuel consumption, amount of fuel remaining (by using an optional fuel sensor), plus boost and oil pressures. The alarm function monitors 16 alarm indicators and interactive command window displays the parameter details. The alarm system also logs the sequence of events for advance troubleshooting.
