Although we specialize in Propeller Shafts and Shaft Couplings, we are proud to boast that we also are excellent at Custom Machining, Custom Fitting, Custom Fabrication, Metal Cutting, Boring, and Castings.
We work with exotic metals including Steel, Stainless Steel, Cast Iron, Bronze, Copper, Brass, Titanium, Magnesium, 17-4PH, and Aluminum.
We’ve been known to work on anything that proves to be a challenge for the average machine head.
Established in 1990 as San Diego Boat Works we transitioned to Dynamic Marine Machining. We are a family owned business serving Shelter Island and beyond.
