CATMAR · MARINE TECHNICAL SERVICE · BARCELONA
Marine engine, propulsion and generator services
Diagnostics, planned maintenance and repair in the workshop and on board, with the scope defined around the equipment, symptoms, location and vessel conditions.
Send the information available. If an inspection or diagnostic attendance is required first, that intervention will be quoted before it takes place.
Identify the right next step
Technical service starts with the complete system
The same symptom can have different causes. Equipment identification, installation details, history and operational status help CATMAR review the request and prepare an appropriate scope.


Yacht tender engines and propulsion
Onboard and workshop maintenance and repair for yacht tenders. See our work on Volvo Penta D6 engines and DPH propulsion.
Diagnostics and fault finding
For starting problems, alarms, overheating, smoke, vibration, loss of power or unexpected behaviour. The dedicated repair page explains what to send and how diagnostic work is scoped.
Marine engine repair
Mechanical and associated electrical work defined from the checks performed and the actual condition of the equipment. Further work proceeds against an approved scope.
Repowering and new engines
Free repowering assessment and technical study, with an engine proposal and quotation for supply, installation and commissioning.
Planned and winter maintenance
Maintenance planned around manufacturer, model, operating hours, calendar, use and observed condition. End-of-season work helps identify requirements in time.
Marine generators
Diagnostics, preventive maintenance and repair for generators installed on board, covering the relevant systems and information required for each unit.
Propulsion and drives
Where manoeuvring or power delivery is affected, the engine, transmission, controls and installation need to be considered together.
Associated electrical and electronic systems
Checks related to engines, generators, starting, charging, controls or alarms where they form part of the technical intervention.
Workshop and onboard attendance
The right location depends on the equipment, access, dismantling requirements and nature of the job. CATMAR operates from Port Balís and Port Esportiu del Masnou and reviews attendance at other ports according to scope, access and planning.
Multi-brand capability
The make guides the process; the installation defines the job
Send the manufacturer, model, serial number where available, hours, alarms and details of any recent related work. CATMAR will review the equipment and scope before confirming the next step.
