Marine engine maintenance

Tailored preventive maintenance plans so your vessel's engine performs at its best and never leaves you stranded at sea.

Preventive maintenance of a Baudouin marine engine in the engine room

At sea, any breakdown can become a serious problem for the vessel and the crew. That is why HTC Mechanic works preventively: we design marine engine maintenance plans that detect any sign of wear or failure early, before it becomes an emergency.

Each plan is tailored to your engine, its running hours and the way you use your boat, whether commercial fishing or leisure, always following the manufacturer's recommendations. So you can sail safely, without interruptions or extra costs.

Anticipating is the best way to look after your vessel.

What the maintenance includes

  • Oil change and oil, fuel and air filter replacement.
  • Cooling system check: water pump, heat exchangers and hoses.
  • Inspection of the fuel injection and supply system.
  • Check of belts, mounts, transmission and gearbox.
  • Testing of alarms, sensors and instrumentation.
  • Engine condition report with recommendations.

Frequently asked questions

Marine engine maintenance

How often should a marine engine be serviced?

It depends on running hours and the manufacturer's recommendations, but as a general rule we recommend at least one full service a year. A preventive plan schedules filter, oil and wear-part changes in advance.

Can you service the engine in my port?

Yes. We are based in Sanlúcar de Barrameda (Cádiz) and travel to ports and shipyards across mainland Spain and the islands.

Do you work on engines of any brand?

We specialise in marine diesel engines and are an official Baudouin agent, and we also work on engines from other brands. Tell us which engine you have and we will advise you.
