Marinsa sells, supervises installations, commissions, and services medium-speed diesel propulsion engines (Wabtec V228, L250, V250 series including MDC EPA Tier 4 / IMO Tier III compliant variants) for tugboats, supply vessels, tuna and sardine purse seiners, ferries, offshore vessels, and government maritime applications. It also distributes EMD-compatible parts, Masson-Marine gearboxes, Kobelt marine controls, Kocsis hydraulic accumulators, and TDI pneumatic starters, with 15,000+ engines deployed globally across nine countries.

The company's core technology includes proprietary MS-1 and MS-2 engine controllers (developed in-house and launched in 2023) that integrate with the WebSupervisor remote-monitoring platform for real-time engine data, email/SMS alerts, and mobile app access. Marinsa operates a direct enterprise field-sales model through regional offices in Miami (HQ), Seattle, Panama City, Lima, Manta, Buenos Aires, Santiago, Puerto Naranjo, Vigo, and Bergen, providing 24/7/365 bilingual service, shipyard supervision, commissioning, overhauls, turbocharger reconditioning, and parts logistics with same-day shipping to most of Latin America. Revenue derives from one-time engine and parts sales, professional service contracts, and recurring aftermarket support, with quote-based pricing across enterprise commercial maritime and government customers including the Panama Canal Authority and Chilean Navy.
