Intake & Through-Hull Cleaning

Restricted seawater flow can overheat engines, stress pumps, and trip AC systems. We clear marine growth and debris from intakes, strainers, and through-hull openings to restore reliable cooling. Service is performed by experienced divers using safe, controlled techniques.
