Shafting

DH Porter & Company manufacture precision marine shafts to exacting standards, whether working from a supplied sample or detailed specifications.

All shafts undergo inspection and straightening prior to CNC machining. Each is turned, keyed, and finished to suit the vessel’s drive system, ensuring reliable performance and minimal vibration.

We machine shafting in premium materials including:

• 316 CG
• SAF 2205
• Marinox
• Aquamet 22

Shafts are typically produced in diameters from ¾" to 4", with custom sizes available on request.
