Yamaha - Air Shroud Cylinder 2 - Cooling System Component - 7FK-12652-00-00

Overview

Air shrouds like this don’t get much attention, but they’re key to keeping your engine running evenly. It helps guide airflow right where it’s needed around the cylinder, especially when the motor’s working hard. I’ve seen uneven temps across cylinders just from missing or damaged shrouds. When everything’s in place, the engine just runs smoother and holds temperature better.

Key Features

• Focused Airflow Routing – Directs cooling air specifically around cylinder two for balanced temperature control.
• OEM Form and Fit – Built to match factory design for proper airflow alignment and coverage.
• Heat-Tolerant Construction – Handles constant engine heat and vibration in marine environments.
• Supports Even Engine Cooling – Helps reduce hot spots that can affect long-term engine performance.

Engine & Boat Compatibility

Designed for Yamaha outboard engines that use cylinder-specific air shrouds as part of the cooling airflow system. Commonly used across a range of Yamaha outboards where proper airflow direction is critical for engine reliability.

FAQ

Q: What happens if this air shroud is cracked or missing?
A: Air won’t be directed properly, which can lead to uneven cooling and possible overheating in that cylinder.

Q: How often should I check this part?
A: It’s a good idea to look it over during routine maintenance, especially if you’ve had the engine apart.

Q: Can this impact overall engine performance?
A: Yes, uneven cooling can cause the engine to run less efficiently over time.

Q: Does saltwater use wear this part out faster?
A: Heat and salt exposure can make materials brittle, so regular inspection helps catch issues early.

Q: Any installation tips?
A: Make sure it’s seated correctly and not interfering with surrounding components so airflow stays consistent.
