MTU 20V 1163 TB73L Marine Engine Parts
Alfa Marine Spare Parts supplies MTU 20V 1163 TB73L marine engine spare parts for commercial vessels, fast ferries, government and naval vessels, offshore applications and other high-power marine installations.
We can assist with fuel injectors, fuel-system components, turbochargers, charge-air cooling components, water pumps, oil-system parts, filters, sensors, electronic components, cylinder heads, pistons, liners, bearings, gaskets, seals and engine overhaul parts.
The 20V 1163 TB73L belongs to the MTU Series 1163 engine family. Different Series 1163 models and configurations can use different components, so replacement parts should be identified using the complete engine model, engine serial number and existing part number whenever available.
MTU 20V 1163 TB73L Engine Overview
The MTU 20V 1163 TB73L is a 20-cylinder V-configuration, four-stroke diesel engine developed for high-power marine propulsion applications.
The TB73L is part of the wider Series 1163 family, which includes different 12V, 16V and 20V engine configurations and later M-designation variants.
Because fuel-system components, turbochargers, pumps, cooling components, sensors and internal engine parts can vary between Series 1163 engines, MTU 1163 alone is not sufficient information for reliable parts identification.
When requesting replacement components, provide the complete designation:
MTU 20V 1163 TB73L
together with the engine serial number whenever possible.
