🔧 Product Description

Genuine Volvo Penta raw water impeller kit measuring 51 mm wide, weighing 0.234 kg and listed for 58 applications across the AQ, BB, MS, DP, SP and SHIELD series. Width is the ordering detail: the accessories catalogue lists two impeller kits side by side for the same engine groups, this one at 51 mm and 21951346 at 31 mm, so measure the impeller you are taking out. It is listed for the AQ225 to BB261 group, the AQ231 to BB231 group and the 500, 501, 570, 571, 572 and 740 range. Supplied as a kit so the seals and gaskets packed with it go back together with the new impeller.

🔌 Function

Draws raw water through the pump and pushes it round the cooling circuit, its flexible vanes sweeping the housing to make the pumping action.

⚠️ Common Signs of Failure

• Weak or missing telltale flow at the exhaust outlet
• Overheating alarm, particularly after running dry even briefly
• Vanes found set, cracked at the roots or torn off
• Rubber gone hard, glazed or swollen and sticky
• Housing or wear plate scored where the vanes have run

🛠️ Service Notes

• Measure the width of the impeller you are removing - 51 mm takes this kit and 31 mm takes 21951346
• A puller screw is listed for drawing the impeller out of the pump without damaging the housing
• Account for every vane, never run the pump dry, and prime the pump before the first start
• Always refer to the operator's manual for the recommended maintenance and service intervals for your engine and drive
• Listed against more than one engine or drive family - check the qualifier that applies to your own engine or drive
