This caged needle bearing replaces the original connecting rod lower bearing in Mercury 3-cylinder 4-cylinder and V6 3.0-liter outboard engines across looper Optimax EFI and Pro XS configurations. Manufactured to match or exceed specifications for proper fit and durability in the demanding marine outboard environment where saltwater and high RPM create extreme bearing loads. The bearing cage maintains proper needle roller spacing and alignment ensuring consistent load distribution across the crankshaft journal during engine operation. A worn or damaged connecting rod bearing can cause excessive crankshaft play knocking and eventual engine failure if not replaced during rebuild. Confirm your engine model and part number before purchasing to verify proper fitment. Verify your part number before purchasing to confirm fitment for your specific engine.
