Description
Marine Propeller Overview
A propeller is the rotating blade system that converts engine power into thrust for outboard motors. Key characteristics:
- Materials: Typically aluminum (cost-effective) or stainless steel (high performance)
- Design Elements: Blade count (3-5 blades), pitch, diameter, and rake angle affect speed/efficiency
- Performance Impact: Proper selection improves fuel efficiency by up to 30% and reduces vibration
- Applications: Matched to engine HP (e.g., 9.9-300HP outboards) and boat type (fishing, cruising, etc.)
Modern designs incorporate cupped blades and progressive pitch for optimal water flow. Always consult OEM specifications when replacing propellers to ensure compatibility with your outboard’s gear ratio and intended use.
