Johnson Pump — Impeller Service Kit — 09-5000 — 189-095000

Johnson Pump Impeller Service Kit 09-5000 (189-095000)

Johnson Pump 09-5000 is a complete service and rebuild kit for F5-series Volvo Penta raw-water pumps. The distributor stock number 189-095000 corresponds to this kit. Rather than a basic impeller-only swap, it supplies the main wear and sealing components needed to service the applicable crankshaft-driven seawater pump.

Kit Contents

• 1 flexible impeller
• 1 O-ring
• 1 lip seal
• 1 ball bearing
• 1 retaining ring
• 4 pump-cover screws
• 1 lubricant pack

Compatible Applications

• Volvo Penta engines using the Johnson F5-series crankshaft-driven raw-water pump, including 4.3GXi, 4.3OSi, 5.0GXi, 5.0OSi, 5.7Gi, 5.7GXi, 5.7OSi, 5.7OSXi, and selected 5.7GiI / 5.7GXiI variants
• Fitment references span A through F pump-generation variants depending on engine model and original pump configuration
• Broader catalogs also associate this kit with many 1999-2005 Volvo Penta 3.0L, 4.3L, 5.0L, 5.7L, and 8.1L crankshaft-mounted seawater pump applications

Fitment Notice

Identify this kit by the actual seawater pump, not engine displacement or model name alone. Use it where the pump is a Johnson/Volvo Penta F5-series unit requiring Johnson 09-5000. Volvo Penta changed raw-water pump configurations during production, and later pumps can require a different service kit with a larger impeller. On 2005-era engines especially, confirm the existing pump number and impeller dimensions before ordering.

When This Part Needs Replacement

• Cracked, hardened, permanently bent, or missing impeller vanes
• Water leakage from the pump shaft or seal area
• Rough or noisy pump bearings
• Excessive shaft movement
• Reduced seawater flow or recurring overheating
• Corrosion or contamination found during pump inspection
• Pump disassembly, where the old seals and O-ring should not be reused

If pieces are missing from the old impeller, inspect the downstream cooling passages and heat exchanger for debris before returning the engine to service.

Installation Notes

Inspect the pump housing and shaft before rebuilding; a service kit replaces wear components but will not correct a badly scored housing, bent shaft, or damaged pump casting. Lubricate the replacement impeller during assembly and verify the O-ring and lip seal are seated correctly. Rotate the pump during assembly as needed to fold the impeller vanes into the housing without cutting them. Follow the applicable Volvo Penta or Johnson Pump service procedure for the exact installation.

Technical FAQ

Is this an impeller-only kit?
No. It's a full pump service kit covering the impeller, O-ring, lip seal, ball bearing, retaining ring, screws, and lubricant.

How do I know if I need this kit instead of an impeller-only kit?
If the F5 pump also needs its bearing, shaft seal, and internal sealing components serviced rather than just the impeller, this kit covers that job.

How do I confirm fitment?
Identify the pump as a Johnson F5 / 09-5000 unit rather than matching by engine size alone, since pump configurations changed during production.

Parts Desk Insights

Best use case: Servicing an F5 raw-water pump that needs more than the impeller replaced, since this kit also covers the bearing, shaft seal, and internal sealing components in one purchase.

Most common mistake: Choosing a kit by engine size or model name instead of confirming the actual pump identification; the Johnson F5 / 09-5000 match is far more reliable than going by displacement alone.

Sizing/fitment guidance: Confirm the pump number and impeller dimensions before ordering, especially on 2005-era engines where Volvo Penta changed raw-water pump configurations and some pumps need a kit with a larger impeller.
