Yanmar 4LH-STE Marine Inboard Diesel Engine 230HP Turbocharged
The Yanmar 4LH-STE 230HP marine inboard diesel engine combines turbocharged, intercooled power with a 3.455-litre, four-cylinder diesel platform. Its direct-injection design and factory-listed 169 kW / 230HP one-hour rating at 3,300 rpm make it a model to consider for an inboard engine replacement or shaft-drive repower where the vessel’s requirements match its operating profile.

Key Features for Marine Repower Buyers
- Turbocharged and intercooled: Combines compressed intake air with charge-air cooling.
- Direct fuel injection: Uses a mechanical diesel injection system.
- Freshwater engine cooling: Transfers engine heat through separate freshwater and seawater circuits.
- Four-cylinder configuration: Provides a starting point for assessing engine-room space, mounting positions and service access.
- Shaft-drive installation: Factory documentation identifies a marine transmission arrangement for conventional propeller-shaft propulsion. Manualzz
For buyers replacing an existing 4LH-STE, matching the nameplate details, gearbox configuration and connection points can help define the work required for the repower.
