Marine Diesel, Inc.

Marine Diesel, Inc., doing business as Marine Diesel, manufactures precision mechanical components and hardware for the Defense Logistics Agency as a prime contractor, with a self-certified small disadvantaged business (SDB) posture and 100% of recent federal awards held as a prime. The Seattle-based for-profit Subchapter S corporation competes predominantly in full-and-open procurements—most awards carry no set-aside designation, though a subset of its idefinite delivery contracts are reserved for small businesses.

Marine Diesel's capability portfolio centers on commercial off-the-shelf mechanical components essential for military maintenance and operational readiness: spacer sleeves, spacer rings, shaft components, clutch halves, valve seats, bearings, bushings, mounting brackets, retaining rings, collars, washers, disks, and associated fastening hardware. Recent awards span the full range of order magnitudes. Representative prime work includes a $36,299.88 total small business set-aside purchase order from DLA Land and Maritime in August 2023 for seat valves; a $33,312.10 total small business set-aside purchase order from DLA Land and Maritime in February 2024 for seat valve components; and a $16,425.50 purchase order from DLA Land and Maritime in February 2023 for shouldered shaft components. The company has secured over 75 prime contract awards since its federal procurement registration in April 2002, with individual order values historically ranging from under $100 to approximately $36,300.

Customer concentration is extreme and narrow. The Defense Logistics Agency (DLA) accounts for 510 of 547 awards (93% coverage), split across three operational divisions: DLA Aviation (236 awards, $3.1 million combined potential value), DLA Land and Maritime (204 awards, $2.6 million combined potential value), and DLA Troop Support Hardware (35 awards, $5.1 million combined potential value). The potential-value ranking diverges slightly from award count: DLA Troop Support Hardware anchors $5.1 million across just 35 awards (higher order values), while DLA Aviation's 236 awards carry $3.1 million (smaller, more frequent orders). Marine Diesel serves no significant non-DLA customer base within the recent award portfolio.

Marine Diesel holds six active Indefinite Delivery Contracts with DLA, each valued at $250,000 ceiling, with ordering periods extending through 2029. The most recent IDC—a $350,000 single-award contract with DLA Aviation awarded September 29, 2026—runs through September 2031. All prior IDCs ($250,000 ceilings each) were awarded between September 2021 and June 2024. Three of the six are set aside for small businesses (Total Small Business designation); three carry no set-aside. Under these vehicles, DLA issues firm fixed-price purchase orders and delivery orders on an as-needed basis, with order values ranging from $47 to over $36,000 per transaction. The top five parent vehicles by task-order count (SPE4A616D5655, SPE4A621D5AV5, SPE5EY14D0533, SPE4A616D5608, SPE4A723D60EZ) account for 58 task orders combined and $304 thousand in potential value.

Activity trajectory has declined modestly year over year—26 awards in 2022, 34 in 2023, declining to 18 in both 2024 and 2025, with only 4 awards recorded in 2026 to date. The recompete exposure within the next twenty-four months is minimal: only one award carries an ultimate completion date within that window, representing $4 thousand in combined potential value. However, the September 2026 IDC award and the existing six active contracts with 2029–2031 completion dates signal ongoing DLA demand and contract stability through the decade.

Work is performed entirely at Marine Diesel's manufacturing facility in Seattle, Washington (9448 17th Ave SW, Seattle, WA 98106). The vendor's capability portfolio is classified by NAICS under Hardware Manufacturing (174 awards), Mechanical Power Transmission Equipment Manufacturing (89 awards), and Ball and Roller Bearing Manufacturing (66 awards). By PSC code, the dominant categories are Bushings, Rings, Shims, and Spacers (173 awards) and Miscellaneous Power Transmission Equipment (98 awards).
