Propeller Shafts
Our 17-4 Shafts are precision machined with a standard propeller shaft taper, milled for 1/4" key and threaded with 3/4" standard thread on 1" and 1-1/8" shafts. Standard sizes are listed, or as a special service, we will cut to your specified length. Please allow approximately one week for this service. Overall length can be determined by measuring from the coupling in the boat to the aft end of the strut, and adding 5" for 1" shaft.
Double Taper Option for Easier Installation
For replacing a shaft or a NEW shaft for your Glen-L or other boat, we recommend a factory-assembled shaft and coupler set with a Double Taper on the shaft. These assemblies are precision bored, honed, faced, straightened and balanced to ensure concentricity and reduce vibration and shaft whip. Materials are the highest quality available in the industry and all machining meets or exceeds ABYC standards.
These assemblies are shipped complete with the prop shaft and coupler as a "loose fit" so the shaft and coupler can be disassembled for installation. Please use these directions for measuring:
Order Item #MH-760 below in addition to your prop shaft for the double taper option.
