    Yacht engineering services

    At Heavy Seas we specialize in all types of engines including inboard engines, outboard engines and waterjets, regardless of the brand. Due to our extensive experience in marine engineering, we have worked on, removed and attached engines, inboards and outboards of all sizes and brands and can offer our expertise on both diesel and gasoline engines.   

    A malfunctioning engine can lead to a multitude of problems and we believe that it is essential that boats can continue to function throughout the season. At Heavy Seas, we offer engine substitution services in case of breakdown, refurb and refit periods, or tune ups to keep boats on the water. During yard periods, we will store, expand or work on engines for hibernation and winterising ensuring that they are ready and functioning when required.    

    We also offer boat hydraulic services in Mallorca that cover all of the systems on board that are used to control the propellers as well as the repair of shafting and transmission. Using state-of-the-art computerised diagnostic tools we are able to meet the requirements of the latest boats and technologies on board for our clients and suppliers. All of our systems are constantly updated to ensure that we leave nothing unchecked and ensure that everything is working as it was designed to. 

    Every yacht engineering solution that we offer is fully guaranteed and we make sure to assess each client based on their recommended revisions and maintenance according to the brands that have been used and their navigation hours. As Heavy Seas is based in Mallorca, Spain, we can be onboard or in port quickly in cases of emergency and we are always on hand to answer questions, doubts and queries.
