🔧 Keep your engine leak-free and running smooth — never miss a seal!
This 20-piece gasket set is designed as a direct replacement for worn drain plug washers on Mercury MerCruiser and Johnson Evinrude lower unit gearcases. Compatible with multiple OEM part numbers, these gaskets ensure a reliable, leak-proof seal for 3/8-16 drain/fill screw holes, making routine oil changes hassle-free and preventing costly oil leaks.

Correct size for 5 hp mercury 4 stroke
Fits the drain and fill holes perfectly. Had to replace the old ones. The old ones were smashed from the previous owner over tightening the screws.
