Technical Specifications

Precision Machining & Overhauls

When critical components fail, long lead times from manufacturers destroy tight schedules. We fabricate custom marine-grade replacements and rebuild high-load systems to exact tolerances in our dedicated Seattle facility.

CNC Billet Fabrication

We program and cut custom replacement shafts, brackets, and specialized fittings from high-strength marine-grade alloys. Absolute dimensional tolerance is verified before delivery.

Hydraulic Overhauls

Complete diagnostics and rebuilding of high-load winches, steering gear, and complex hydraulic power units. We restore system pressure and seal integrity to strict OEM standards.
