Propellers: Whatever your needs, we turn propellers faster. From recreational to mega-yacht, commercial and government vessel propellers, we’re committed to getting you the best possible performance regardless of your propeller’s size, material, or number of blades. Our team has decades of experience in propeller repair. Our craftsmen know how to work with all metal alloys used in the marine industry. We can skillfully braze bronze and other soft metals, weld steel and stainless steel, and perform heliarc assembly of aluminum and alloys to add replacement material without affecting tensile characteristics. Shafts: For shafts that are worn, pitted, or damaged, we offer specialized metalizing for precise and even surface reapplication, bringing old shafts to smooth like-new condition while saving thousands over the cost of buying new. When shaft straightening is needed, our specially designed 400-ton roller presses, combined with years of R&D in the field, give us a clear edge over others in the industry. Our experience and equipment mean we can straighten new and repaired shafts beyond original specs to meet strict ISO 484/2 standards. Sizing capabilities include shafts up to 40 feet long and with diameters up to 8 inches. After selecting the perfect material, our team turns, grinds, and smooths the shaft for a precise and balanced finish that meets the owner or builder’s exact specifications and meets or exceeds ABYC-P6, ASE J755, ABS Rules for Shipping, and ISO 484/2 standards. We can create individual shafts utilizing CAD design and CNC machining accuracy to ensure true tapering, keyways, threads and thrust plate ends. H&H turnkey shafts systems scope and size complimentary parts including: prop nuts, keys, couplings, sleeves, struts, and props, and anything in between to satisfy your exact propulsion needs.
