The main difference between an aluminum and brass hub kit is that brass is softer and therefore more compliant in a crash, protecting the motor. Aluminum is stronger, lighter, and more durable, but less compliant. Brass is therefore more suitable for recreational use where the risk of contact with objects is higher, while aluminum is better for applications where durability and weight are crucial.

Brass hub kit:
- Material: Softer than aluminum.
- Advantage: Provides better protection for the engine and gears because the material can yield in the event of an impact or collision with an object.
- Disadvantage: Less strong and durable than aluminum.
- Application: Often used for recreational boats where the chance of contact with objects is greater.
