Mack Boring & Parts

What Mack Boring & Parts does

Mack Boring & Parts Co. is a privately held, fourth-generation family-owned marine and industrial engine distributor headquartered in Somerset, New Jersey, founded in 1922 by Ed McGovern Sr. The company distributes a broad portfolio of propulsion and power-generation products sourced from multiple OEMs, including Mercury outboards (2.5-600 HP), MerCruiser sterndrives, Mercury diesel, Mercury Avator electric outboards, Yanmar marine diesels (14-800 HP), Scania marine and industrial diesels (250-1150 HP), Isuzu industrial diesels (21-282 HP), ePropulsion electric motors, WhisperPower generators (3.5-18 kVA), and powertrain components from ZF, Twin Disc, Aquadrive, and the company's own Global Power Products sub-brand. The company serves recreational marine, commercial marine (including fishing, ferries, patrol, workboats), industrial off-highway, and military segments (notably 2kW and 3kW TQG generator programs). Revenue is generated primarily through hardware distribution via a network of 500+ factory-certified authorized dealers across North and Central America, supplemented by direct sales, a Dealer Advantage Network e-commerce platform (ecommerce.mackboring.com), and a factory-certified technical training business with published course pricing of $200-$1,050 per attendee and over 20,000 cumulative graduates. The company employs 101-250 people and is led by President Patrick McGovern with a professional management team including COO Jon Henkin and Director of Sales & Marketing Scott Dubrow. Strategic emphasis has shifted in the mid-2020s toward marine electrification through the ePropulsion line and Mercury Avator, and toward alternative-fuel compatibility, evidenced by the June 2025 Viking Yachts RD99 renewable diesel demonstration on Scania V8 engines and the 2026 Maine Island Institute 'Wattson' electric lobster workboat deployment.

Scale indicators4 records

Recent moves13 records

Expansion highlights6 records

Direct peers

• Volvo Penta: Major marine engine manufacturer and distributor serving recreational and commercial marine markets globally. Direct competitor in marine diesel propulsion and a benchmark for Mack Boring's multi-brand distribution model, with the difference that Volvo Penta is an OEM-owned channel.
• Land 'N' Sea: Marine parts and accessories distributor serving a multi-brand dealer network across the U.S. Closest pure-play comparable to Mack Boring in distribution model - both aggregate marine products (parts, engines, accessories) for resale through independent dealers.

Broad incumbents

• Caterpillar Marine: Marine and industrial engine division of Caterpillar, serving commercial marine, offshore, and workboat markets. Overlaps with Mack Boring's Scania industrial and Yanmar 6AY continuous-duty lines for high-horsepower commercial applications.
• Yanmar: Japanese diesel engine manufacturer and Mack Boring's longest-running distribution relationship (since 1974). Yanmar also sells direct in many geographies, making it both a partner and a potential competitive threat to Mack Boring's U.S. marine diesel franchise.
• Mercury Marine: Brunswick-owned manufacturer of marine propulsion and a key principal supplier to Mack Boring. Both share recreational and commercial marine customers; the difference is Mercury Marine is an OEM and Mack Boring is one of its largest North American distributors.
• Cummins: Global manufacturer of diesel engines with a substantial marine and industrial business. Comparable to Mack Boring's Scania, Isuzu, and Yanmar lines in end applications (commercial marine, industrial off-highway), though Cummins sells direct and through its own dealer network rather than as a multi-brand distributor.
• Brunswick Corporation: Marine conglomerate (Mercury Marine, Boston Whaler, Sea Ray, etc.) with significant powertrain and propulsion assets. Compares to Mack Boring as a broader marine industry player; Mack Boring is a downstream channel partner for Brunswick's Mercury brand.

Others

• Twin Disc: Manufacturer of marine transmissions (35-4000+ HP) that Mack Boring distributes through its Powertrain Center. Directly comparable product line, with Mack Boring acting as a key North American channel partner.
• ZF Marine: Marine transmission, propulsion, and steering systems manufacturer whose gearboxes Mack Boring distributes. Both serve the same boat builders and fleet operators with integrated propulsion packages.

Emerging players

• ePropulsion: Chinese marine electric propulsion manufacturer whose products Mack Boring distributes in North America. Emerging competitor in marine EV with rapidly expanding I-Series, X-Series, and Navy product lines, and a current Mack Boring principal.
