What Indmar Products does

Indmar Products (legal entity Tennessee Propulsion Products, LLC) designs, marinizes, and manufactures gasoline-powered inboard marine engines for the recreational watersports market, with its world headquarters and primary manufacturing facility in Millington, Tennessee. The portfolio centers on the Raptor Series (Raptor 400, 440, 460, and ROUSHcharged 575) built around Ford's 6.2L V8 platform with Roush Performance supercharging, the 2.3L EcoBoost — the first turbocharged direct-injection inboard in its segment — and the EcoJet jet propulsion package for the pontoon category. Supporting revenue comes from a proprietary parts and service product line including lubricants, filters, transmission fluids, antifreeze, marine grease, and the patent-pending Strainer Pro sea-strainer system.

The company sells exclusively through a dual channel: direct OEM relationships with watersports boat builders (Tigé, Supra, Moomba, MB Sports, Sanger, Pavati, Kyma, MotoJet, and others) where engines are installed at the factory, and an authorized dealer network of more than 1,600 showrooms across North America supported by distribution centers in Millington TN, Merced CA, and Clarkston WA. All engines carry a 5-year factory warranty administered directly by Indmar, and the company maintains certified service technician training and dedicated factory representatives at each OEM partner. In November 2022, Indmar was acquired by Correct Craft and now operates as part of its Liberty Technologies subsidiary alongside PCM, Crusader, Levitator, and Velvet Drive, while retaining its own brand, team, and Millington headquarters. The company holds ISO 9001:2015 certification and has received 23 consecutive Marine Industry Customer Satisfaction Index Awards from the NMMA.

Scale indicators6 records

Recent moves7 records

Expansion highlights6 records

Direct peers

• PCM Marine Engines: PCM is a sister company of Indmar within Correct Craft's Liberty Technologies division and manufactures inboard marine engines for ski, wake, and surf boats. It is Indmar's most direct internal competitor, sharing parent portfolio resources and customer relationships.
• Crusader Engines: Crusader is another Liberty Technologies sister brand producing inboard marine engines, historically used in offshore fishing and pleasure craft. Despite shared ownership, it competes head-to-head with Indmar in the gasoline inboard segment.
• Ilmor Engineering: Privately held engine developer and manufacturer with a dedicated marine division (Ilmor Marine) producing high-performance inboard engines for premium wake and surf boats. Closely comparable as a private, performance-focused inboard specialist targeting the same OEM customers as Indmar.

Broad incumbents

• Mercury Marine (Brunswick Corporation): Mercury Marine is Brunswick Corporation's marine propulsion subsidiary and the dominant supplier of outboards, sterndrives, and inboards across recreational boating. It competes with Indmar across multiple segments but at much greater scale and with a far broader portfolio.
• Volvo Penta: Volvo Penta is Volvo Group's marine propulsion division, supplying diesel and gasoline inboards, sterndrives, and complete driveline systems globally. It overlaps with Indmar in gasoline inboards and competes on premium OEM relationships, though its business extends well beyond wakeboats.
• Yamaha Marine: Yamaha's marine business sells outboards, inboards (including wakeboat-targeted Jet Drive systems), and WaveRunners. Its scale, powersports integration, and dealer reach make it a broad incumbent competitor to Indmar even though its inboard share in wakeboats is smaller.
• BRP (Bombardier Recreational Products): BRP manufactures marine propulsion (Evinrude outboards, Rotax engines) plus a full line of powersports vehicles. While primarily outboard-focused, BRP's Rotax-engine DNA parallels Indmar's strategy of leveraging non-marine automotive-grade platforms in marine applications.

Emerging players

• Cox Marine: Cox Marine is an early-stage New Zealand-based pioneer of diesel outboard engines, an emerging technology segment. It is comparable to Indmar as a focused, engineering-led disruptor that is establishing a new propulsion category rather than competing head-on with incumbent V8 inboards.
• Torqeedo: Torqeedo is a leading manufacturer of electric marine propulsion systems for leisure boats, now part of Yamaha Marine. It represents the emerging electric alternative that could compete with Indmar's hybrid-electric Kyma program and longer-term erode the gasoline inboard opportunity.
• Pure Watercraft: Pure Watercraft develops electric outboard propulsion systems aimed at pontoon and recreational boating — directly addressing the same displacement Indmar targets with its EcoJet inboard jet package. It is comparable as a propulsion-category disruptor rather than a same-technology competitor.
