27-43115M – Gasket – Mercury / MerCruiser (Old Stock)

The 27-43115M Mercury gasket gives you a genuine OEM marine seal for Mercury and MerCruiser marine engine systems. This gasket plays an important role in engine sealing. It sits between mating surfaces and stops oil, water, and gases from escaping. Because it is genuine Mercury old stock, it retains proper shape and sealing characteristics.

This gasket works in various Mercury and MerCruiser applications where factory seals matter. Many boat owners and mechanics replace worn or damaged gaskets during routine service and top-end rebuilds. When you install the 27-43115M Mercury gasket, you restore proper sealing and help keep fluids where they should be.

Also, this gasket helps prevent leaks that can lead to overheating, low oil pressure, or drivability issues. Good sealing helps your engine run more consistently in a range of conditions, whether you’re cruising, trolling, or working your boat hard. Furthermore, correct gasket fit and compression reduce the chance of blow-by and improve longevity for internal components.
