The Quicksilver 8M0214998 is a genuine OEM propeller bore sleeve designed for select Mercury outboard motors. This white plastic component plays a critical role in your outboard's exhaust system and propeller performance.
Key Features:
- Genuine Quicksilver/Mercury Marine OEM part for reliable fit and function
- Seals the gap between the propeller hub and gearcase to prevent exhaust gas escape
- Helps eliminate propeller ventilation and slip for improved thrust and performance
- Prevents metal-to-metal contact, reducing wear and vibration on the propeller shaft
- Simple snap-in installation when replacing worn or damaged sleeve
This propeller bore sleeve is essential for maintaining optimal performance on compatible Mercury outboard motors. The sleeve creates a seal at the leading edge of the propeller hub, ensuring exhaust gases are properly diverted through the propeller rather than escaping around it. Without this component or when damaged, you may experience excessive propeller slip, cavitation, loss of power, or unusual vibration.
