Quiet power for boats that leave the dock.
Marine diesel generators and hybrid lithium systems, specified, installed and cared for with the attention your yacht deserves. Vessels from 30 to 120 feet.
One crew for the whole power system.
From a new generator package to a no-start before a holiday weekend, the same dedicated technicians look after your vessel's power from specification through the life of the set.
Sales & installation
New generator packages specified to your real load, fuel system and engine-room space. Mounts, exhaust, fuel, sound shields and wiring handled end to end.
Service & repair
Diagnostics, cooling-system rebuilds, injector and governor work, and control-panel faults. Our vans carry the parts most jobs need, so repairs happen at your slip.
Maintenance plans
Annual and hour-based service: impellers, belts, zincs, fuel filters, oil analysis and load testing, all logged to your vessel's service file.
Hybrid off-grid systems
Lithium banks, inverter/chargers and solar that carry overnight loads without the generator, cutting run hours, fuel and noise at anchor.
Engine-room work done to spec.
Every install follows ABYC and manufacturer guidelines and is load-tested before we hand over the keys. You get the paperwork to prove it.

"Our Kohler quit on a Friday night off Fire Island. They talked us through a fix by phone, then had a rebuilt raw-water pump waiting at the slip in Freeport on Monday."
"We spend most of the summer on the hook. The lithium and inverter upgrade means the generator runs about two hours a day instead of eight, and we finally sleep without it droning."
"They maintain the gensets on all six of our charter boats. Service is logged, parts are on the van, and we haven't lost a booking to a power failure in three seasons."
"Clear quote, install finished on the date they gave us, and the engine room was cleaner when they left than when they arrived."
At your slip, anywhere on Long Island.
Based in Massapequa, our mobile technicians attend marinas, yacht clubs and private docks across Nassau and Suffolk counties, with New York Harbor and Connecticut by arrangement.
