Boat shaft AQ - 17

Marine Hardware™, Inc. worked for years with most of the world’s leading stainless steel bar mills to provide the ultimate in boat shafting quality. By combining our field experience with our metallurgical excellence, our goal is to bring to our customers a product that is superior in materials and exacting tolerances. Our aquanox™ shafting is used in yachts manufactured by Bayliner, Maxum, and Luhrs, to ski boats such as Malibu and Fineline as well as Unlimited Hydroplanes like the Miss Budweiser and Miss Bardahl. We supply bars in type 17, 19, 22 and 22HS with diameters ranging from 1 inch thru 4 inches. Our lengths are available to 32 feet. Our computer-controlled Mazak turning centers make prime quality shafting, part after part. We start with aquanox™ precision polished and ground modified 304 or 316 nitrogen stainless steel, and turn the taper, thread, and journal simultaneously in a Hardinge collet, not in a chuck which must be readjusted for each part. Our tapers have less than .002” runout, and the threads are Class 2 fit. After turning, keyways are cut to exacting standards which have proved over time and in the field to prevent shaft breakage at this critical area. Then we proceed with balancing and straightening to a tolerance of .002” on 42” intervals. This is 300% better accuracy than specified in American Boat and Yacht Council (ABYC) standards
