Yamaha - Gear Pump Assembly - Lubrication System Component - 69W-43830-00-00

Overview

When it comes to keeping an engine alive under load, proper lubrication is everything. This gear pump is what keeps oil moving where it needs to go, especially when you’re running hard or for long stretches. When it’s working right, you don’t think about it—but when it’s not, things go bad fast. It’s one of those critical components you replace when you want peace of mind and steady protection inside the motor.

Key Features

• Consistent Oil Flow Delivery – Circulates lubricant through the engine for proper internal protection.
• Precision Gear Operation – Uses tightly matched gears to maintain steady pressure and flow.
• Durable Internal Construction – Built to handle continuous operation under heat and load.
• OEM Fit and Function – Designed to Yamaha specifications for reliable installation and performance.

Engine & Boat Compatibility

Designed for Yamaha outboard engines using this style of gear-driven lubrication pump. Commonly used across mid-range Yamaha applications where consistent oil circulation is essential for engine longevity.
