Before work proceeds
The engine and installation must be identified correctly.
A useful assessment starts with the actual equipment configuration and the conditions under which the issue occurs.

- Engine model and configuration.
- Serial number, where available.
- Operating hours and known maintenance history.
- Alarms, symptoms and recent work.
- Vessel location, access and operational status.
CATMAR is an Official STEYR Marine Service and confirms the technical scope for each engine and intervention.
Diagnostics
We gather symptoms, available codes and background and check the related systems before proposing a repair.
A single alarm is not an automatic diagnosis. State whether the engine starts, whether the vessel can proceed and when the issue first appeared.
Maintenance and repair
The scope may include planned maintenance, fault finding and mechanical or electrical work within confirmed capability.
Workshop and onboard support for captains, chief engineers and yacht managers, according to the work and vessel access.
For rescue boats, this service concerns the engine. It does not include or replace a complete statutory inspection or certification of the rescue boat or launching equipment.
Parts and warranty matters are confirmed for the specific engine and intervention.
Technical scope
Defined by the engine and installation.
We review the engine and requested work to prepare diagnostics, maintenance and parts with the right technical context.
- Preventive maintenance based on the engine and its history.
- Diagnostics and fault finding.
- Mechanical or electrical work within confirmed scope.
- Control and associated transmission checks where relevant.
- Parts support assessed for each intervention.
Scope is confirmed according to the engine, installation and requested work.
