Perkins M245C Marine Engine Spare Parts
The Perkins M245C Marine Engine is part of Perkins' new generation of marine propulsion engines developed for both commercial vessels and leisure marine applications.
The M245C sits at the top of the initial three-engine platform alongside the M175C and M200C. Perkins specifies the M245C as a six-cylinder propulsion engine producing 249 hp (186 bkW) at 2400 rpm. Production of the new range was scheduled to begin in 2026.
Unlike the older mechanically controlled Perkins marine engines found in many vessels, the M245C represents a newer propulsion platform. Independent industry reporting describes the range as turbocharged, aftercooled and common-rail fuel injected.
Alfa Marine Spare Parts supports Perkins M245C Marine Engine Spare Parts requirements for scheduled servicing, commercial vessel maintenance, yacht repairs, new-build projects, repowers and longer-term engine support.

Perkins itself confirms the six-cylinder configuration, 249 hp/186 bkW rating at 2400 rpm, 500-hour service interval, gear-driven water pumps, automatic valve-lash adjustment and self-tensioning belt. Perkins also offers heat-exchanger or keel-cooled configurations.
Because this is a configurable propulsion platform, the exact equipment installed on a particular M245C should always be checked using the engine identification and build specification.
How Much Power Does the Perkins M245C Produce?
The Perkins M245C is rated at:
249 hp / 186 bkW at 2400 rpm.
It is the highest-output engine among the initial new Perkins marine propulsion trio:
- M175C — 173 hp / 129 bkW
- M200C — 200 hp / 149 bkW
- M245C — 249 hp / 186 bkW
All three are rated at 2400 rpm.
Is the Perkins M245C a Six-Cylinder Engine?
Yes.
The Perkins M245C is a six-cylinder marine propulsion engine.
The platform was developed to provide robust propulsion for demanding marine applications while offering configuration flexibility for different vessel installations.
