Aqualoy® Marine Propeller boat shafts undergo more quality controls than any competing brand. These boat shafts are used in a wide variety of applications such as work boats, pleasure craft, and naval vessels. The Aqualoy® process produces a rounder, straighter, stronger shaft.

Consistent & Accurate Tapers
At Deep Blue Yacht Supply, we use an onsite CNC machine to eliminate human error during machining.  In addition, our engineers perform rigorous quality assurance tests before shipping. The production time for this process is usually 3-4 days.

Custom Dimensions
Please note that our single-taper machining follows the SAE J755 specification.  In addition, our CNC engineers can provide a wide array of custom shaft dimensions.  For non-standard dimensions and double-tapered shafts, our engineers will be more than happy to review your dimensions to ensure the proper fit.

For diameters greater than 3", lengths greater than 108", or custom specifications, please feel free to contact our shaft specialists at (800) 454-6960 or you can use our 'Shaft Inquiry Form' to request a quote.
