Leqian Marine Propeller shafts undergo more quality controls than any competing brand. These prop shafts are used in a wide variety of applications such as work boats, pleasure craft, naval vessels, and pumps. The leqian process produces a rounder,straighter, stronger shaft.
Leqian stainless shafts are available in 304L, 316L, and SS630. All of our shafts from 3/4" - 4" diameter are precision machined in our Mazak Nexus 350M CNC turning lathe to insure all machining is within .0005".304L Single Tapered Shafts All single tapered 304L shafts will have a propeller taper machine according to SAE J755 specifications, unless other instructions are given. In addition to the propeller taper machining, a single square keyway will be machined for the coupling end of the shaft. The dimples for the set screws can only be machined with the coupling in place. If you purchase a coupling from us, there will be a $115.00 to fit and face the coupling to the shaft and during this process, the dimples for the set screws will be completed.
304L Double Tapered Shafts All double tapered 304L shafts will have a propeller taper machine according to SAE J755 specifications, unless other instructions are given. In order for us to machine the coupling taper, we will require either a drawing of the coupling taper or the following dimensions must be specified(as there is not an SAE standard for coupling tapers and these tapers do vary); length of taper, small end diameter of taper, and length and size of threads.

Using Effects
This stainless steel shaft has the highest strength and hardness of all stainless steel boat shafting alloys with diameters greater than 2 inches. Corrosion resistance is comparable to Type 304. 304L is typically used in a workboat environment due to its strength in larger diameters.
Packing & Delivery
We use a variety of packaging methods such as long plastic boxes, tubular foam, and woven shafts to protect the propeller shafts from bumps and scratches and ensure the proper installation and operation of the propeller shafts
