A marine propulsion assembly includes a propeller having a threaded hub whose threads are used for engaging with a drive shaft. The drive shaft includes both a first set of threads and second set of threads such that the first set of threads are used to engage with a keeper nut and a second set of threads are used to engage within the propeller hub. The first set of threads are configured to be opposite the direction of propeller rotation for preventing rotation of the keeper nut while the second set of threads are configured opposite the direction of rotation of the propeller to prevent the propeller from loosening on the drive shaft. The drive shaft further includes a tapered section for providing a stop to the propeller when engaging with the second set of threads.
