Repair. Rebuild. Restore.

When your generator goes down, revenue stops. Hospitals go on battery backup. Data centers face outages. Commercial buildings lose tenants' confidence. Ships sit at berth. Production lines halt. We exist to shorten that window — with a fully equipped Brooklyn shop, a trained mobile crew, and a documented process that gets your system back online the first time.

Seaboard Marine Electric provides generator repair, rebuilding, and service across all three of our specialties — commercial, marine, and industrial — throughout New York City and the Tri-State area. Diesel and gas systems of every scale, from a single commercial building's standby unit to fleets of prime-power generators at industrial sites and aboard vessels.

Repair vs. Rebuild — Both, Depending

The right answer depends on the asset, the cost to replace, the downtime tolerance, and the remaining service life of the core components. We do both.

  • Repair — targeted fix of the failed component. Fastest turnaround, lowest cost. Right answer when the asset is otherwise in good condition.
  • Rebuild — full tear-down, inspection, replacement of consumables and worn components, precision machining where needed, reassembly to factory spec. Restores service life at a fraction of replacement cost. Right answer for end-of-life engines where the asset still has value.

All Three Specialties

  • Commercial — office towers, hospitals, data centers, hotels, residential high-rises. NFPA 110 compliance, insurance audit documentation, minimal disruption to building operations.
  • Marine — commercial vessels, yachts, tugboats, offshore. Coast Guard, ABS, DNV-GL standards with complete documentation. Dockside and shop service. Marine generator detail →
  • Industrial — manufacturing, petrochemical, food processing, wastewater, utilities. Prime-power applications, continuous-duty rebuilds, specialty fuel and explosion-proof work.
