Frequently Asked Questions
What is the primary function of a shaft key?
A shaft key serves to lock the propeller hub to the drive shaft, ensuring they rotate as a single unit and preventing slippage under load.
What is the significance of 316 stainless steel for marine use?
316 stainless steel contains molybdenum, which significantly enhances its resistance to pitting and corrosion caused by chloride ions found in saltwater, ensuring longevity.
Can this key be used for engine drive shafts other than propeller shafts?
While designed for propeller shafts, its standard dimensions might be suitable for other marine drive shaft applications requiring a similar keyway connection.
What tools are typically needed for installation?
Installation generally requires a prop puller to remove the propeller and basic hand tools for securing the propeller nut.
What is the critical measurement when selecting a shaft key?
The critical measurements are the width of the keyway in both the shaft and the propeller hub, and the length of the keyway to ensure proper engagement.
