Yanmar Mastry Engine Center, LLC

Yanmar Mastry Engine Center, LLC (doing business as Mastry Engine Center), a foreign-owned for-profit marine powertrain specialist, supplies Suzuki outboard engines, diesel marine propulsion components, and vessel re-powering and maintenance services to federal maritime agencies as a prime contractor on full-and-open and total small business set-aside purchase orders. Headquartered in Clearwater, Florida, Mastry operates exclusively as a prime (100% of awards) with no subcontract footprint.

The vendor's customer concentration is stark and concentrated on a single customer. The U.S. Coast Guard (Department of Homeland Security) accounts for 87 of 107 recent awards and $1.1 million in combined potential value — 93% and 79% respectively of the active portfolio. The Federal Law Enforcement Training Center (DHS) is the second customer by count with 5 awards ($195 thousand), followed by the Navy's Naval Air Systems Command (3 awards, $106 thousand), the Navy's Naval Sea Systems Command (2 awards, $15 thousand), and the Army, Special Operations Command, and other DoD components representing smaller activity. The two top customers by award count and potential value track identically — the Coast Guard dominates both measures.

Recent representative awards illustrate Mastry's recurring contract profile. On March 13, 2026, FLETC awarded a $40.6 thousand firm fixed-price purchase order for Suzuki outboard DF300APXX marine engines and associated parts, scheduled for completion by April 16, 2026. On March 25, 2025, FLETC awarded a $39.9 thousand total small business set-aside purchase order for two 300HP Suzuki marine engines and specialized components to support maritime training vessels in Charleston, South Carolina. On June 11, 2024, FLETC awarded a $39.8 thousand purchase order for two Suzuki 300HP marine engines and associated parts as replacement equipment. On May 11, 2022, the Coast Guard awarded a $17 thousand purchase order for vessel re-powering support on the CGC Venturous. On January 6, 2022, the Coast Guard awarded a $50.1 thousand total small business set-aside purchase order for hull troubleshooting and re-powering on the CGC Diligence.

Activity has declined significantly. Mastry averaged four awards per year in 2022 but has placed only one award per year since 2023 — one in 2024, one in 2025, one in 2026. The combined potential value across all 107 awards in the source data (spanning 2003 to present) totals $1.4 million, with $1.4 million already obligated. Across NAICS and PSC classification, Mastry's work sits in industrial machinery and equipment wholesale (36 awards), marine and ship equipment wholesale and maintenance (26 combined awards under transportation equipment and ship repair PSCs), and diesel engine manufacturing and components (11 awards). The vendor operates across full-and-open procurements and total small business set-asides but does not sit on government-wide vehicles or multi-award IDIQs.
