Yamaha - Intake Manifold Gasket - Air Intake Sealing - 6EK-13761-00-00 / 6EK-13761-01-00

Overview

Gaskets aren’t the most exciting parts, but when one fails, you’ll know it quick—rough idle, poor performance, or air leaks that throw everything off. I’ve replaced plenty of these on Yamaha setups, and it’s one of those fixes that can bring an engine right back to life. This gasket sits right where airflow matters most, so it needs to seal clean and tight every time. Get it right, and the motor breathes the way it’s supposed to.

Key Features

• Air-Tight Seal Performance – Prevents unwanted air leaks between intake components for proper engine operation.
• Stable Engine Idle Support – Helps maintain consistent airflow for smooth idle and throttle response.
• Heat-Resistant Material – Built to handle engine temperatures without breaking down over time.
• Precision Cut Fitment – Matches Yamaha intake surfaces for proper alignment and sealing.
• Reliable Long-Term Use – Designed to maintain sealing integrity under continuous engine operation.

Engine & Boat Compatibility

Designed for Yamaha outboard engines with intake manifold systems requiring a sealing gasket between components. Commonly used across mid-range Yamaha outboards in both recreational and commercial marine applications. Suitable for freshwater and saltwater environments where proper air intake sealing is essential.

FAQ

Q: What are signs this gasket is failing?
A: Rough idle, poor acceleration, or a hissing sound from the intake area can indicate an air leak.

Q: Should I replace this gasket every time I remove the intake?
A: Yes, it’s always best to install a new gasket to ensure a proper seal.

Q: Any tips for installation?
A: Clean both surfaces thoroughly and make sure the gasket is aligned correctly before tightening.

Q: How does saltwater exposure affect this gasket?
A: The gasket itself holds up well, but corrosion around mounting surfaces can affect sealing if not maintained.

Q: Can an intake leak affect fuel efficiency?
A: Yes, extra air entering the system can throw off the air-fuel mixture and reduce efficiency.
