Did you know
- The Caterpillar C15 marine engine is a descendant of the mechanically-injected 3406C engine, which was later upgraded to the electronically managed 3406E. The C15 itself was first introduced around 1998 or 1999.
- The C15 is positioned as a powerful inline-six diesel engine within Caterpillar's marine offerings, sitting above the C12 and C13, and as a slightly smaller displacement option compared to the C18.
- The C15 is often chosen for its reputation for reliability, durability, and strong power delivery, making it suitable for demanding marine applications such as commercial fishing vessels, charter boats, and high-performance yachts.
