Common MerCruiser Engine Applications

-
MerCruiser 5.7L V8

Function
The bell housing hose carries raw cooling water from the sterndrive through the transom assembly to the engine’s cooling system. Over time the hose can become brittle, cracked, or restricted due to heat and age.
Replacing the hose kit helps:
-
Maintain proper engine cooling
-
Prevent water leaks in the transom assembly
-
Ensure unrestricted cooling water flow
-
Protect the engine from overheating
Important Compatibility Note
Cooling hoses and transom components can vary depending on drive model, transom assembly design, and serial number range. Always verify compatibility using the engine and drive serial number before ordering to ensure the correct replacement kit.
