PRODUCT DETAILS:
Direct replacement center main bearing outer race for Mercury and Mariner 2-stroke looper outboard engines ranging from 65HP through 125HP. This outer race replaces the original hardened steel bearing race at the center main crankshaft journal in Mercury looper outboard engines manufactured from 1985 through 2005. The outer race is the stationary component of the center main bearing assembly against which the loose needle rollers rotate, providing the critical bearing surface for crankshaft support. Manufactured to match or exceed specifications for proper fit and surface hardness in the demanding marine outboard environment. The center main position is one of the highest-loaded bearing locations in the crankshaft assembly, making outer race condition critical for engine reliability and longevity. A damaged or worn outer race will allow excessive crankshaft movement and can lead to needle roller damage, crankshaft scoring, and eventual engine failure if not replaced. Confirm your engine model and part number before purchasing to verify proper fitment.
