SEI Propeller Shaft Bearing Carrier (Mercury Compatible)
The SEI Propeller Shaft Bearing Carrier is a high-strength marine bearing, specifically designed for Mercury Outboard Motors, replacing the original OE# 818763A11 / 43567T1. It is manufactured to OEM tolerances to support rotating shafts in stern drive and drive shaft systems, minimize axial/radial friction, and ensure vibration-free operation.
