Caterpillar C27 Marine Engine
The Caterpillar C27 is a V12, four-stroke diesel engine with approximately 27 litres displacement. Different C27 configurations have been produced for propulsion and power applications, so parts should not be selected from the engine model alone.

The C27 can be found in applications including:
- Motor yachts
