Applications & Compatibility
The CM3.27 fits a focused range of small- to mid-sized vessel builds and repower jobs:
- Motor cruisers and small displacement launches
- Day cruisers, workboats, and fishing boats needing extra power over the CM2.16
- Compatible with the ZF10 gearbox setup for straightforward drivetrain integration
- Suited to repower projects replacing older, less efficient boat diesel engines
Built for Boat Builders & Dealers
Craftsman Marine treats builders and distributors as long-term partners, not one-off buyers. The CM3.27’s Mitsubishi platform keeps replacement parts and trained technicians within reach almost anywhere a boat ends up, and manuals covering six languages mean a regional team is rarely left guessing.
Because every engine leaves the factory to the same specification, OEM lines and bulk orders stay simple to plan, with the distributor network there to back up the sale afterward.
Technical Advantages
Stepping up from the CM2.16 to a 3-cylinder block brings a few specific advantages worth knowing:
- Indirect cooling with a heat exchanger keeps raw seawater away from internal components
- Energized-to-stop solenoid gives a dependable, fail-safe shutdown
- 10 A circuit breaker for straightforward electrical protection
- Optional calorifier connection for onboard hot water without extra retrofitting
Why Choose the CM3.27
Builders and dealers pick the CM3.27 as much for the aftercare as for the extra torque over the CM2.16. Common parts, predictable servicing and compliance already handled keep the vessel’s working life free of surprises.
- Mitsubishi-based industrial engine platform, proven and supported worldwide
- Cupronickel heat exchanger and seawater-resistant cast exhaust bend for long-term corrosion resistance
- Indirect cooling system that protects internals from raw seawater
- Complies with RCD II regulations for recreational craft
- 113 kg build with flexible CM type 3 (front) engine mounts for straightforward installation
