What H&H PROPELLER AND SHAFT does
H&H Propeller and Shaft is a Salem, Massachusetts-based marine driveline service company founded in 1950, specializing in the customization, fabrication, and repair of propellers and shafts. Its core work covers all marine driveline components — propellers (custom fabrication, new sales, repair), custom-machined inboard shafts up to 40 feet long, shaft repair and straightening (including shafts up to 7 inches in diameter via metalizing processes and a 400-ton roller press), struts, rudders, and couplings — supported by ABS-certified tailshaft cladding and conformance to ISO 484/2, ISO 10010, ABYC-P6, and ABS Rules for Shipping. Analytical and quality tooling includes HydroComp Prop Expert propulsion analysis, 3D MRI propeller mapping, Dynamics Research Multi-Plane Computerized Balancing, and CNC turning and milling.
The company reopened under new ownership circa 2022, retaining 10+ veteran craftsmen while upgrading and expanding workshop capabilities and integrating with sister facilities at ThermoCraft Engineering to combine for over 100,000 sq. ft. of fabrication and reconditioning space. It sells through direct field service across the Northeastern United States (Maine, Vermont, New Hampshire, Massachusetts, Connecticut, Rhode Island, and New York), a marina partner referral network, an online repair request system, and channel relationships with nine propeller distributors (Michigan Wheel, Hung Shen, Veem, Acme, Max Prop, Gori, Martec, ZF/Faster, and Teinbridge). Services are quote-based, billed as one-time project work for propeller and shaft fabrication/repair, with the Prop Doctor seasonal maintenance program providing a recurring-service component for recreational boaters. Customer segments span recreational boaters (primary), marinas, East Coast shipyards, and commercial and government vessel operators.
