Prevent cooling system failure with the Sinera Marine precision-machined Impeller Drive Key 28-43037. This stainless steel key is a direct OEM-specification replacement for the water pump assembly in MerCruiser Alpha One (Gen I) and R/MR sterndrives manufactured between 1983 and 1990. Designed to resist shear forces and corrosion, it is a vital component for any lower unit water pump overhaul.
Crafted from high-strength, wear-resistant materials, the 28-43037 Drive Key withstands extreme RPMs, vibration, and harsh marine conditions, making it ideal for engine rebuilds, sterndrive repairs, or performance restoration. Compatible with both R/MR Alpha One Sterndrive and Transom Assembly models (1983–1990), it guarantees a precise fit and reliable operation every time.
