3837935 Seawater Pump | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta impeller from the Cooling System group, weighing 9.367 kg and listed for 10 applications on TAMD series engines. It consolidates two earlier numbers, 3825493 and 876809, both of which were catalogued as seawater pumps, so at 9.367 kg the part supplied is a substantially larger item than the word impeller suggests.
