Your trusted marine mechanic in southern Spain
For more than 30 years, HTC Mechanic has looked after marine diesel engines for fishermen, skippers and owners who need a reliable vessel with no surprises, in both commercial fishing and leisure boating.
You don't need to be a mechanic to notice that something isn't right: an unusual noise, a fuel leak or a strange vibration can be the first sign of a serious fault. We diagnose the problem and fix it before it leaves you stuck in port.
- Preventive maintenance tailored to each vessel.
- Accurate fault diagnosis on marine engines.
- Technical assistance in port, in the boatyard or at sea.
Your goal is ours: to sail and work safely.

Baudouin marine engines for demanding working conditions
As an official Baudouin agent and marine diesel specialists, we recommend the 650 hp Baudouin 6M33.2 for trawlers: strong response in continuous operation and optimised fuel consumption.
It is an engine built to perform in real working conditions, combining durability, efficiency and consistent output day after day. We advise you on choosing, supplying and installing the engine that best suits your vessel.
Real experience, in the workshop and on board

Common questions about marine mechanics
Where does HTC Mechanic work?
We are based in Sanlúcar de Barrameda (Cádiz, Spain) and travel to ports and shipyards across mainland Spain and the islands. We also carry out international projects, such as work in Portugal and the maintenance of a yacht in Miami.
What types of marine engines do you repair?
We work on diesel, electric and hybrid marine engines for commercial and leisure vessels. We specialise in diesel engines, we are an official Baudouin agent, and we supply spare parts from brands such as Weichai and Yuchai.
Do you carry out inspections before buying a boat?
Yes. We carry out technical pre-purchase inspections of the engine and the main systems on board to detect faults, wear or poor maintenance before you close the deal.
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 maintenance plan schedules filter, oil and wear-part changes in advance and helps prevent breakdowns at sea.
Do you sell Baudouin engines and spare parts?
Yes. As an official Baudouin agent we advise on, supply and install Baudouin marine engines and genuine spare parts, as well as high-quality marine accessories.
Do you explain how the engine works when you buy it?
Yes. When you buy a Baudouin engine through HTC Mechanic we run a hands-on product presentation so your crew understands how it works, the alarm panel, start-up and shutdown procedures and routine maintenance.
