What This Bearing Does

This center main bearing supports the crankshaft inside compatible Mercury and Mariner 2.5L V6 powerheads.

Center main bearings help maintain crankshaft alignment, reduce friction, and support smooth crankshaft rotation while the engine is running under load.

During a powerhead rebuild, replacing worn main bearings is critical for protecting the crankshaft, rods, pistons, and internal rotating assembly.

This bearing is commonly used by marine technicians and engine builders when rebuilding Mercury 2.5L V6 fishing, performance, and SportJet engines.
