Sierra 18-2375 Drain Plug Magnet, Replaces Mercury/Mercruiser 10-14834, 3/8 Inch Stainless Steel

The Sierra 18-2375 Drain Plug Magnet is a stainless steel magnetic drain plug used to seal a gearcase or engine drain/fill opening while also catching ferrous metal particles suspended in the lubricant. As oil circulates past the plug, the built-in magnet attracts fine metal filings generated by normal gear and bearing wear, giving you an early visual warning of internal wear before it becomes a costly failure. The plug has a 3/8 inch thread size and a round head, and is machined from stainless steel for corrosion resistance in a marine environment.

This drain plug is intended for use with the Sierra 18-2945 Drain Screw Gasket, which seals the plug against the housing and should be replaced whenever the plug is removed and reinstalled. The 18-2375 is a direct cross-reference replacement for multiple OEM and aftermarket part numbers spanning Chrysler, Mercury, and MerCruiser applications, so it can be used as a like-for-like swap wherever those original numbers are called for. Each Sierra part is built to meet or exceed the specification of the original equipment part it replaces.
