Restore Your Vintage Outboard with FASWORX Over time, the original factory gaskets in your Johnson or Evinrude outboard will naturally degrade, lose elasticity, and fail. This leads to poor engine performance, water intrusion, oil leaks, and compression loss. The FASWORX Premium Powerhead Gasket Set is engineered to exact OEM specifications, providing a precision, factory-quality seal for your 2-stroke outboard powerhead rebuild. Why Choose FASWORX? Whether you are performing routine maintenance on an aging motor or tackling a complete powerhead restoration, this complete cylinder and crankcase kit provides the heavy-duty, marine-grade reliability you need to get back on the water safely. Our gaskets are precision-cut to match the exact tolerances of the original OMC/BRP blocks.
