Yamaha - Oil Tank - Engine Lubrication System - 6H3-21707-06-00

Overview

Oil delivery is something you don’t want to second guess, especially on a two-stroke setup. I’ve seen cracked or aging tanks cause air leaks and inconsistent oil flow, and that’s where bigger problems start. This is one of those parts you replace to eliminate risk and keep things simple. When it’s right, you don’t think about it—you just run the motor and trust it’s getting what it needs.

Key Features

• Integrated Oil Storage – Holds and supplies oil to the engine’s lubrication system for consistent delivery.
• Reliable Oil Flow Support – Helps maintain steady oil supply to protect internal engine components.
• OEM Fitment Design – Built to Yamaha specifications for proper mounting and connection.
• Durable Tank Construction – Designed to resist cracking, warping, and wear in marine conditions.
• Essential System Component – Supports proper operation of the engine’s oil injection system.

Engine & Boat Compatibility

Designed for Yamaha outboards equipped with compatible oil injection systems. Commonly used across a range of small to mid-size two-stroke engines found on fishing boats, skiffs, and recreational vessels. Always verify compatibility with your specific engine before installation.

FAQ

Q: What are signs my oil tank needs replacing?
A: Cracks, oil leaks, air bubbles in the lines, or inconsistent oil delivery are common signs.

Q: Can a faulty tank affect engine performance?
A: Yes, if oil flow is interrupted, it can lead to poor lubrication and potential engine damage.

Q: Is this difficult to install?
A: It’s usually straightforward, but you’ll want to make sure all lines are properly connected and sealed.

Q: Do I need to bleed the system after installation?
A: In many cases, yes—it’s important to remove air from the oil lines to ensure proper flow.

Q: Does saltwater exposure impact the tank?
A: Over time, yes. Heat, vibration, and environment can cause wear, so regular inspection is a good idea.
