Propulsion engines

C280-6

The Cat® C280 commercial propulsion engine series is engineered for high‑utilization workboat applications where power, durability, and uptime matter most. Delivering up to 23% more power with increased durability, the C280 series combines high power density, proven heavy‑duty build, and long service intervals to help operators move more, pull harder, and stay working longer, day after day, compared to previous C280 models.
