Albin Group Premium Impeller Kit 57 x 12.7 x 20mm - 12 Blade - Key Insert

The Albin Group Premium Impeller Kit 57 x 12.7 x 20mm – 12 Blade – Key Insert is a critical replacement component for marine cooling and water circulation systems on recreational and professional vessels. After years on the water, any angler or boater knows that engine reliability depends entirely on proper cooling flow, and a worn or damaged impeller will starve your cooling system faster than a snapped line on a trophy fish. This 12-blade design is engineered to move water volume efficiently through your engine block, keeping temperatures stable during extended runs in shallow or debris-laden water where standard impellers fail.

Built to Albin Group's premium specifications, this impeller measures 57mm in diameter with a 12.7mm bore and 20mm width—dimensions that ensure compatibility with specific marine pump housings and shaft configurations. The 12-blade design maximizes water displacement per revolution, delivering consistent cooling capacity even when inlet screens collect fine sand, silt, or plant matter common in coastal and freshwater fishing grounds. The key insert secures the impeller to the drive shaft with positive engagement, eliminating slip and ensuring predictable performance. This compact kit weighs just 0.15 lbs, making it easy to store as an onboard spare—a practice any experienced skipper will recognize as essential insurance against mid-trip cooling failures.

Boaters operating inboard, jet drive, or raw-water cooling systems will benefit from keeping this replacement impeller kit aboard, particularly those running shallow water or operating in sandy bays where standard elastomer impellers wear prematurely. Installation is straightforward for anyone with basic mechanical aptitude—the key insert design means no timing concerns, just slide, seat, and secure. Verify your engine's pump housing dimensions (57mm impeller, 12.7mm bore, 20mm width) against your service manual before ordering to ensure proper fit and function on your specific vessel.
