Ideal for higher horse power engines or if running a 2 or 3-blade propeller. The tensile strength is 130,000 to 135,000. Available in 1" and 1-1/8" diameter. Shafts are precision machined with a standard propeller shaft taper, milled for 1/4" key and threaded with 3/4" standard thread. Standard sizes are listed below, or we will cut to your specified length at no additional charge.
Note: Shafts are available with a taper at both ends. There is an extra machining charge for the taper on the engine end. See 90-760. Before ordering a double tapered shaft, see this drawing and instructions.
