Yamaha - Impeller Housing - Jet Pump Component - 6CR-R1312-00-00

Overview

If you’ve spent time around Yamaha jet pumps, you know how much the housing affects the way the boat or WaveRunner actually feels on the water. I’ve seen worn housings cause cavitation and kill acceleration even when everything else looked fine. The Yamaha Impeller Housing 6CR-R1312-00-00 is what keeps water moving clean and controlled through the pump. When it’s in good shape, you get that strong hookup and smooth pull Yamaha is known for.

Key Features

• Optimized Water Flow Path – Maintains smooth water movement through the pump for strong acceleration and efficiency.

• Yamaha Engineered Fit – Built to match factory jet pump specifications for proper alignment and performance.

• Durable Marine Construction – Designed to resist wear, corrosion, and impact from debris in the water.

• Supports Peak Propulsion Performance – Helps reduce cavitation and maintain consistent thrust.

• Direct Replacement Component – Installs in place of the original housing for straightforward service.

Engine & Boat Compatibility

The Yamaha Impeller Housing 6CR-R1312-00-00 is designed for Yamaha WaveRunners and jet boats equipped with jet pump propulsion systems.

It is commonly used across a range of Yamaha personal watercraft and jet boat applications where maintaining proper water flow and pump efficiency is critical. Always confirm compatibility using your specific model and parts diagram before installation.

FAQ

Q: What are signs of a worn impeller housing?
A: Loss of acceleration, cavitation, or a slipping feel when throttling up are common signs.

Q: Can a damaged housing affect top speed?
A: Yes, poor water flow can reduce both acceleration and overall top-end performance.

Q: Is this something I can replace myself?
A: If you’re comfortable working on jet pumps, it’s doable, but alignment and sealing are important.

Q: Does debris damage the housing over time?
A: Yes, sand and small debris can cause wear inside the housing and reduce efficiency.

Q: Should I replace the impeller at the same time?
A: It’s a good idea to inspect both and replace them together if there’s noticeable wear.
