Faqs
Frequently Asked Questions About Yanmar 6GY Marine Engine Spare PartsWhat is the Yanmar 6GY Marine Engine?
The Yanmar 6GY Marine Engine, including the 6GY135W, is an inline six-cylinder, four-stroke commercial marine diesel engine designed for demanding propulsion applications.
The modern 6GY135W combines:
- Inline six-cylinder construction
- Common-rail direct fuel injection
- Turbocharging
- Intercooling
- Four valves per cylinder
- Electronic engine control
- Heat-exchanger cooling
The engine family is used in commercial marine applications where high power output, reliability, and continuous operating capability are important.
Is the Yanmar 6GY a Six-Cylinder Engine?
Yes.
The Yanmar 6GY135W has six cylinders arranged inline.
The 6GY135W has approximately:
- Bore: 135 mm
- Stroke: 170 mm
- Cylinder arrangement: Inline 6
- Operating cycle: Four-stroke
Exact specifications should always be matched to the particular engine model and rating.
Is the Yanmar 6GY a Four-Stroke Engine?
Yes.
The Yanmar 6GY operates on the four-stroke diesel cycle:
- Intake
- Compression
- Combustion and power
- Exhaust
A complete operating cycle takes place over two crankshaft revolutions.
What Fuel System Does the Yanmar 6GY Use?
The modern Yanmar 6GY135W uses an electronically controlled common-rail direct-injection system.
The fuel system can include:
- Common-Rail Fuel Injectors
- High-Pressure Fuel Pump
- Fuel Supply Pump
- Fuel Rail Components
- Fuel Pressure Sensors
- Fuel Filters
- Fuel Filter Housings
- High-Pressure Fuel Lines
- Injector Seals
- O-Rings
- Electronic Control Components
Do All Yanmar 6GY Engines Use the Same Injectors?
No.
Fuel injector specifications can vary according to the exact engine model and configuration.
Correct injector identification can require:
- Engine model
- Engine serial number
- Existing injector number
- Existing part number
- Duty rating
- Engine configuration
This is particularly important with electronically controlled common-rail components.
Is the Yanmar 6GY Turbocharged?
Yes.
The 6GY135W uses turbocharging together with charge-air cooling.
The turbocharger uses exhaust-gas energy to compress the intake air before it enters the engine.
Available components can include:
- Complete Turbochargers
- Turbocharger Cartridges
- Compressor Components
- Turbine Components
- Bearings
- Seals
- Oil Supply Components
- Oil Drain Components

The intercooler reduces the temperature of this compressed air before it reaches the cylinders.
Available charge-air components can include:
- Intercoolers
- Charge-Air Cooler Cores
- Intake Pipes
- Air Connections
- Hoses
- Clamps

What Is the Difference Between the Yanmar 6GY Coolant Pump and Seawater Pump?
They operate in different cooling circuits.
The coolant pump circulates coolant through the engine's closed freshwater circuit.
The seawater pump moves external raw water through the marine cooling equipment so heat can be transferred away from the engine.
The two pumps therefore perform separate functions within the complete marine cooling system.
Does Every Yanmar 6GY Use the Same Seawater Pump?
Not necessarily.
The exact seawater-pump specification can depend on the engine configuration and marine installation.
Identification can require:
- Engine model
