Lightweight outboard electric motor system

An outboard electric motor kit that includes an electric motor assembly with a unitized propeller hub, a transom mount, a rechargeable electric battery, and an optional recharger. The assembly includes an electric motor unit located in an upper housing. A lower tube stem is attached and that extends downward from the upper housing to a lower housing. Formed on the lower housing is a receiving cavity with a rearward facing propeller hub opening. A drive shaft coupled to the motor unit extends downward inside the lower tube stem and mounted to a gear support block located in the receiving cavity. Mounted on the end of the drive shaft is a main gear. Mounted on the gear support block is a fixed axle that extends coaxially aligned through the propeller hub opening. Extended through the opening and coaxially mounted over the fixed axle is a removable propeller hub assembly.
