Crossing Indonesia’s seas is not easy. Large waves, salty air that corrodes metal, and continuous operational demands force vessel owners to choose engines that resist seawater corrosion and minimize breakdowns at sea. An engine failure offshore is more than a technical problem loss of propulsion, navigation, and lighting can result. For fishing boats, interisland transports, and work vessels, a reliable engine to drive gensets and gearboxes is essential for harsh marine conditions. 

The Tianli 4105‑C marine diesel engine answers that need. This 4 cylinder, 55 HP unit is specifically designed to deliver stable performance in maritime environments. 

Key Advantages of the Tianli 4105‑C Diesel Engine 

1. Reliable Drive for Gensets and Gearboxes 

With 55 HP at 1500 rpm, the engine is powerful enough to drive medium‑capacity ship gensets and propeller gearboxes. The steady 1500 rpm speed helps ensure consistent generator frequency, which is critical for onboard electronics and navigation systems. 

2. Water‑cooler Cooling System 

Tianli 4105‑C uses a water‑cooler system in which the engine’s freshwater is cooled by seawater pumped through a sea‑water pump. Benefits include: 

• Consistently optimal engine temperatures during long operations at sea

• Freshwater coolant that helps protect internal components from corrosion caused by seawater minerals

• Efficient cooling that leverages seawater temperature for continuous heat rejection

3. Electric Starter and SAE 3 Bell Housing 

The electric starter simplifies operation without the need for manual effort, while the SAE 3 bell housing ensures compatibility with a variety of transmissions and marine generators that meet international standards.

Electric Starter and SAE 3 Bell Housing 

The electric starter simplifies engine starting, eliminating the need for manual cranking especially useful when the engine must be started frequently during a workday. 

The SAE 3 bell housing is an international mounting standard between the engine and driven components such as gearboxes or gensets. With SAE 3 compatibility, the Tianli 4105‑C can be directly coupled to a wide range of marine gearboxes and generator sets without additional modification.

What Types of Ships Is It Suitable For?

The Tianli 4105‑C is well suited for: 

• Medium fishing fleets that need reliable gensets for navigation and lighting

• Interisland transport vessels with substantial electrical loads

• Workboats used for survey, patrol, and marine logistics

• Medium‑sized fishing boats for catch operations and onboard processing

• Tourist boats requiring dependable gensets for passenger comfort

Tianli 4105‑C marine diesel engine combines 55 HP power and a water‑cooler system in a unit engineered for reliable, efficient operation across Indonesia’s waters.
