Yanmar 6LY Marine Engine Parts
Yanmar 6LY Marine Engine Parts
What Is the Yanmar 6LY Marine Engine?
The Yanmar 6LY Marine Engine is a well-established inline six-cylinder marine diesel family used in recreational, cruising, performance, repower, and light-commercial vessels.
An important point when sourcing Yanmar 6LY marine engine spare parts is that "6LY" covers several generations. The older mechanical 6LY engines and newer electronically controlled 6LY engines do not all use the same fuel-system and control components.
The family includes engines such as:
- Yanmar 6LYA-STP
- Yanmar 6LY2A-STP
- Yanmar 6LY3-STP
- Yanmar 6LY400
- Yanmar 6LY440
The current 6LY-CR generation consists of the 6LY400 and 6LY440. Yanmar describes these as fourth-generation 6LY engines using Denso common-rail fuel injection and electronic vessel controls.
Alfa Marine Spare Parts supplies OEM, genuine, aftermarket, and remanufactured Yanmar 6LY marine engine spare parts for scheduled maintenance, repairs, fuel-system service, cooling-system repairs, major component replacement, rebuilding, and overhaul requirements.
Yanmar 6LY Technical Information
Because the 6LY family covers different generations, technical specifications should always be connected to the exact engine model.

Yanmar rates the current 6LY400 at 294 kW / 400 mhp and the 6LY440 at 324 kW / 440 mhp, both at 3300 rpm.
What Is the Difference Between Older and Newer Yanmar 6LY Engines?
This is one of the most important questions when ordering parts.
The 6LY family has evolved considerably.
For example, the 6LY2A-STP is a mechanically controlled engine using direct injection with an inline injection pump. Yanmar lists it at 324 kW / 440 mhp at 3300 rpm.
The later 6LY3-STP uses electronically controlled injection.
The current 6LY400 and 6LY440 use a Denso common-rail system and electronic controls.
This means you should never order a component simply by saying:
"I need a part for a Yanmar 6LY."
The complete engine model and serial number are important.
Yanmar 6LY400 Marine Engine
The Yanmar 6LY400 is part of the current 6LY-CR generation.
Key specifications include:
- Rated output: 294 kW / 400 mhp
- Rated speed: 3300 rpm
- Cylinders: 6 inline
- Displacement: 5.813 L
- Bore × stroke: 106 × 110 mm
- Fuel system: Denso common rail
- Aspiration: Turbocharged and intercooled
- Controls: Electronic
- Dry weight without gear: Approximately 585 kg
Yanmar also lists the 6LY400 as HVO-approved.
Yanmar 6LY440 Marine Engine
The Yanmar 6LY440 shares the current 6LY-CR architecture but provides higher rated output.
Key specifications include:
- Rated output: 324 kW / 440 mhp
- Rated speed: 3300 rpm
- Cylinders: 6 inline
- Displacement: 5.813 L
- Bore × stroke: 106 × 110 mm
- Fuel system: Denso common rail
- Aspiration: Turbocharged and intercooled
- Controls: Electronic
- Dry weight without gear: Approximately 585 kg
Yanmar also lists the 6LY440 as HVO-approved.
Yanmar 6LY2A-STP Marine Engine
The Yanmar 6LY2A-STP is an earlier mechanically controlled member of the family.
Yanmar specifies:
- Rated output: 324 kW / 440 mhp
- Rated speed: 3300 rpm
- Displacement: 5.813 L
- Cylinders: 6
- Bore × stroke: 106 × 110 mm
- Combustion: Direct injection
- Fuel system: Inline injection pump
- Aspiration: Turbocharged and intercooled
- Controls: Mechanical
- Dry weight without gear: Approximately 535 kg
This distinction matters when sourcing injectors, injection pumps, control components, sensors, wiring, and associated fuel-system parts.
Yanmar 6LY3-STP Marine Engine
The 6LY3-STP represents another stage in the development of the 6LY family.
Yanmar lists it with:
- 324 kW / 440 mhp
- 3300 rpm
- 5.813 L displacement
- 6 cylinders
- 106 × 110 mm bore and stroke
- Electronically controlled direct injection
- Turbocharging and intercooling
This is another reason why the exact 6LY generation should be identified before selecting spare parts.
