What Solé Advance does

Solé Advance (formerly Solé Diesel), founded in 1912 and headquartered in Martorell, Barcelona, Spain, designs, marinizes, and manufactures marine diesel inboard engines and marine generator sets at a single Barcelona factory. The product range spans compact recreational engines (4-50 CV, MINI series), mid-range propulsion (SM 36-122 CV), heavy-duty and high-performance platforms (SFN 100-210 CV; SV 140-230 CV; SDZ up to 280 CV), and Perkins-based units (45-115 CV), complemented by marine generators from 7 kVA to 180 kVA, including variable-speed models. Proprietary marinization capabilities include keel cooling, dry exhaust systems, custom engine-mounting brackets for repowering, and the SGC 2000 digital converter for remote monitoring. The full product line is HVO-compatible, and an R&D project on hydrogen electric generators is underway under Spain's PERTE Naval program.

The company operates an exclusive, distributor-only go-to-market: all sales, technical consultation, installation, warranty service, and spare-parts distribution are routed through a global network of authorized distributors and service centers, with no direct e-commerce. Revenue is generated from hardware sales (engines, generators, propulsion accessories), spare parts and consumables, repowering solutions, pre-packaged maintenance kits at 50h/250h/500h/1000h intervals, and 3-to-5-year warranties. Customer segments include recreational boaters, sailing-yacht owners, professional/commercial vessel operators, yacht and superyacht builders (OEM channel), and repowering projects — served across Europe (Spain, France, Finland, Sweden, Germany, Netherlands), North America (USA), and Oceania (Australia).

Recent strategic priorities are visible in three concurrent initiatives: a multi-year facility transformation (2025-2027), a hydrogen fuel-cell R&D program launched in late 2025, and active expansion of the international boat-show presence (2026 calendar spanning eight countries). The company is privately held (SOLÉ, S.A., a Spanish sociedad anónima), with no identified external institutional investors, and runs a team of roughly 50-70+ multidisciplinary professionals supported by university partnerships for talent development.

It is a direct peer to Solé with overlapping product portfolio (engines and generators), similar European customer base, and comparable target segments.
• Yanmar Marine: Yanmar is one of the largest marine diesel engine manufacturers globally, with a strong position in saildrive and inboard engines for sailboats and small commercial vessels. Yanmar is also one of Solé's base engine suppliers, making it both a competitor and a critical vendor.
• Westerbeke: Westerbeke is a US-based manufacturer of marine diesel engines and generator sets for sailboats, motor yachts, and commercial vessels. It competes directly with Solé in the marine generator category and shares a focus on quiet, reliable auxiliary power for recreational vessels.
• Volvo Penta: Volvo Penta is the global leader in marine diesel engines and propulsion systems for leisure and commercial vessels. It is a direct peer — Solé explicitly supports repowering Volvo Penta engines — and competes head-to-head in the same engine and generator product categories.
• Beta Marine: Beta Marine is a UK-based specialist in marine diesel engines and generators serving sailing yachts, motorboats, and commercial vessels. It is highly comparable to Solé as a similarly sized European specialist marinizer with comparable product ranges and a strong repowering aftermarket focus.

Broad incumbents

• Mercury Marine (Brunswick): Mercury Marine, owned by Brunswick Corporation, is a leading global manufacturer of marine propulsion systems including inboard, outboard, and sterndrive engines. It competes broadly with Solé in marine propulsion and serves a similar customer base but at far greater scale and brand reach.
• Cummins MerCruiser (Cummins Marine): Cummins is a global diesel engine manufacturer with a substantial marine product line serving commercial vessels, yachts, and naval applications. It is a broad incumbent with vastly greater scale and broader product portfolio but overlapping technology and customer base with Solé.
• Honda Marine: Honda Marine produces a range of outboard and small marine engines as part of Honda's broader power equipment portfolio. It is a broad incumbent with overlapping recreational marine propulsion offerings but does not focus on the inboard diesel and generator niches where Solé specializes.

Emerging players

• ePropulsion: ePropulsion is a Chinese manufacturer of electric outboard and inboard motors for recreational and light commercial marine applications. It is a strategic partner of Solé (Lapeniche-s hybrid canal boat project) and represents the electric propulsion direction Solé is positioning to complement with its generators.
