The Water Passage Gasket 325211 is a critical cooling system component designed to create a watertight seal between engine block cooling passage and cover. Proper sealing is essential to ensure cooling water is directed where it needs to go, helping maintain proper engine temperatures and reliable performance.
Your outboard’s cooling system depends on a network of water passages that circulate cooling water throughout the engine. If a gasket becomes damaged, worn, or deteriorated, water leaks can occur, potentially reducing cooling efficiency and leading to overheating or other performance issues.
Whether you’re performing routine maintenance, rebuilding an engine, or replacing worn cooling system components, installing a new water passage gasket helps ensure proper sealing and dependable operation.
At Liquid Revolutions, we’ve rebuilt countless Johnson and Evinrude engines, and one thing we’ve learned is that cooling system integrity is critical to engine reliability. Replacing gaskets during service is inexpensive insurance against future problems.
Key Features & Benefits

Common Symptoms of a Failed Water Passage Gasket
- Cooling water leaks
- Reduced cooling efficiency
- Overheating concerns
- Visible gasket deterioration
- Water seepage around block and cover mating surfaces
Why Water Passage Gaskets Matter
Cooling water must flow through the engine exactly as intended to maintain proper temperatures. A damaged gasket can allow water to escape or bypass critical cooling passages, reducing cooling system effectiveness.
A properly sealed cooling system helps:
- Maintain engine temperature
- Prevent overheating
- Improve reliability
- Protect engine components
- Support long engine life
Whether you’re rebuilding a race motor, restoring a fishing engine, or performing routine maintenance, the Water Passage Gasket helps ensure proper cooling system operation and dependable engine performance for your Johnson or Evinrude outboard.
