The Volvo Penta 21651097 is a genuine OEM molded water intake hose used in Volvo Penta sterndrive cooling systems. This hose is designed to route raw water internally through the drive assembly, ensuring proper cooling flow from the intake to the engine.
It is a pre-formed (molded) hose, meaning it is shaped specifically for its application—ensuring correct routing, unrestricted flow, and proper fit without kinking or collapsing under suction.
This part is commonly supplied as part of internal water intake hose kits used in modern Volvo Penta sterndrive systems.

Parts Desk Insight
This is an internal hose — not visible once installed. Failures here are tricky because they don’t always leak externally; instead, they cause overheating or poor water flow. If you're servicing a DPH/DP-R drive, replacing these proactively saves a teardown later.
