Design an outboard motor with the following features: 1. **Color Scheme**: Use a matte blue finish instead of black. 2. **Shape**: The motor housing should be slightly more aerodynamic with rounded edges. 3. **Handle**: Replace the straight handle with an ergonomic, contoured grip. 4. **Propeller**: Design a three-blade propeller with an elongated shape for better efficiency. 5. **Display**: Incorporate a digital readout for speed and fuel levels instead of traditional markings. 6. **Weight**: Make it more compact and lightweight for easier handling. 7. **Model Number**: Use a new numeric designation, like "4.5", instead of "5.0". Remove any brand identifiers for a generic look.
