Volvo Penta Impeller Kit 22222936 – Raw Water Pump Service Kit

Part Number: 22222936
Brand: Volvo Penta
Official Product Type: Raw Water Pump Impeller Kit – 6-Blade Service Kit
System: Raw Water / Seawater Cooling

Overview

The Volvo Penta 22222936 is a genuine OEM raw water pump impeller service kit covering a wide range of Volvo Penta diesel and gasoline marine engines, including D1/D2, MD-series, and classic AQ/BB gasoline applications. The kit includes a flexible 6-blade impeller (approximately 2” diameter, slotted shaft-pin drive), sealing gasket(s), and installation lubricant.

This is not the D4/D6 impeller kit — it is primarily for smaller and mid-size Volvo Penta engines. Confirm your engine model, serial number, and pump configuration before ordering.

Kit Contents

Serial Number & Fitment Notice

Impeller selection depends on the engine model and seawater pump configuration. Do not order by engine family name alone — confirm by engine model, serial number, and pump style using the applicable Volvo Penta parts diagram.

Service Interval

Replace the raw water impeller as part of scheduled cooling system maintenance — typically every 2 years or 200–300 hours, whichever comes first, or per the applicable Volvo Penta maintenance schedule. Replace sooner if the vanes are cracked, stiff, permanently bent, torn, or missing. Reduced seawater discharge or unexplained engine overheating can also indicate a worn or damaged impeller.

If blades have broken away, inspect downstream cooling passages and heat exchangers for missing vane material before returning the engine to service.

Installation Notes

Remove the pump cover and inspect the cover plate and pump housing for scoring or excessive wear. Lubricate the new impeller with the supplied lubricant before installation. Install new sealing components supplied with the kit. After reassembly, open the seawater supply, start the engine, and verify strong raw water flow and a leak-free pump housing.

Technical FAQ

Q: Is this the right impeller kit for D4 or D6 engines?
A: No. 22222936 is primarily for D1/D2, MD-series, and AQ/BB gasoline engines. For D4 and D6 engines, see the 21951346 or related D4/D6 impeller kits. Always confirm by engine model and serial number.

Q: What is included in the kit?
A: The kit includes a 6-blade flexible impeller (~2” diameter), sealing gasket(s), and installation lubricant.

Q: How often should I replace the impeller?
A: Every 2 years or 200–300 hours, whichever comes first, or per the Volvo Penta maintenance schedule for your engine. Replace immediately if vanes are cracked, stiff, bent, or missing.

Q: What should I do if impeller blades are missing?
A: Inspect all downstream cooling passages, heat exchangers, and the thermostat housing for missing vane material before restarting the engine. Broken vane pieces can block cooling passages and cause overheating.

Parts Desk Insights

22222936 is the small- and medium-engine Volvo Penta impeller kit — it covers D1/D2, MD-series, and several classic AQ/BB applications. The most common ordering mistake is assuming it fits D4 or D6 engines because many Volvo Penta impellers look similar. Matching the pump and engine model number is the safest way to confirm fitment. When a customer orders this kit, recommend adding the pump cover screw kit (21951334) to the order — it is a low-cost add-on that prevents stripped fasteners on the next impeller service.
