Whether you’re performing a complete engine rebuild or repairing a specific component, this Powerhead Gasket Kit provides the essential gaskets and seals needed for Johnson, Evinrude, and OMC 40-60 HP 2-cylinder outboards.
A powerhead contains numerous sealing surfaces that must work together to maintain proper compression, cooling system operation, crankcase pressure, and overall engine reliability. During any engine disassembly, gaskets should be replaced to ensure proper sealing upon reassembly. Reusing old gaskets can increase the risk of leaks, loss of compression, cooling system issues, and reduced engine performance.
This kit helps simplify the rebuild process by providing the critical gaskets needed to properly reseal the powerhead and restore dependable operation.
At Liquid Revolutions, we’ve rebuilt countless Johnson and Evinrude engines over the years. One thing we’ve learned is that quality gaskets are cheap insurance. A complete gasket replacement during a rebuild helps prevent future problems and ensures the engine performs the way it was designed.
