Sole Diesel

What Sole Diesel does

Sole Diesel, operating today as Solé Advance, is a Spanish manufacturer of marine diesel engines, generator sets, and marine accessories founded in 1914 and headquartered in Martorell, near Barcelona. The company designs and builds marine propulsion engines — offered in configurations including saildrive, inverters, keel cooling, and dry exhaust — alongside type-approved marine generator sets, with optional variable speed (VSC) and parallel configurations. The portfolio is supplemented by control panels, propellers, marine shafts, saildrive units, maintenance packs, and original consumables, plus a dedicated engine repowering ('Remotorizar con Solé') service for renewing propulsion systems on existing vessels. The company also maintains a hydrogen fuel cell R&D initiative aimed at sustainable marine propulsion.

Revenue is generated primarily through hardware sales across engines, generator sets, spare parts, and accessories, complemented by after-sales service and warranty support. Pricing is quote-based and not publicly disclosed. Distribution is executed through a global authorized distributor and dealer network, complemented by direct e-commerce channels on the multilingual (Spanish, English, French) soleadvance.com website and a post-sale customer service portal. The company serves three primary customer segments — leisure boaters, professional maritime operators, and yacht builders/refit yards — with named installations on luxury OEM platforms from Pershing (Ferretti Group), Riva, Galeon, and Azalea Cruises. International reach spans Europe, Oceania, and Asia through direct presence and distributors such as Tekno Marine in Finland, with active participation in international boat shows (Sydney, Helsinki, Sweden). The company is ISO 9001 certified and holds type approval certification for its marine generators.
