Yamaha - Air Shroud Cylinder 1 - Engine Cooling Component - 7CN-E2651-01-00

Overview

Air shrouds are easy to overlook, but they make a big difference in how well an engine handles heat. I’ve seen engines run hotter than they should just from a missing or damaged shroud. These pieces guide airflow right where it needs to go around the cylinder. When everything’s in place, the motor runs cooler and holds up better over time.

Key Features

• Directed Cooling Airflow – Channels air around the cylinder for proper heat management.
• OEM Fit and Coverage – Matches factory design for correct placement and airflow routing.
• Supports Engine Longevity – Helps prevent overheating during extended use.
• Durable Heat-Resistant Build – Built to handle engine heat and vibration in marine conditions.

Engine & Boat Compatibility

Designed for Yamaha outboard engines that utilize air shrouds as part of the cooling system. Commonly used across a range of Yamaha outboards where proper airflow management is essential for maintaining engine temperature.

FAQ
