PRODUCT DETAILS:
Direct replacement center main bearing kit with needle rollers and outer race for Mercury and Mariner 1.5-liter Optimax 3-cylinder 2-stroke outboard engines producing 75HP through 125HP. This bearing kit replaces the original center main crankshaft bearing in Mercury 1.5L Optimax outboard engines manufactured from 2004 through 2012. The center main bearing operates at the middle crankshaft journal where it absorbs significant loads from the rotating crankshaft assembly in the 3-cylinder Optimax powerhead. Manufactured to match or exceed specifications for proper fit and durability required by the high-performance Mercury Optimax direct injection fuel system. The needle roller bearing with outer race provides excellent load capacity and durability essential for the high-RPM operation of Mercury 1.5L Optimax outboard engines. A worn or damaged center main bearing will cause excessive crankshaft play, unusual engine noise, and potential catastrophic failure if not replaced during rebuild. Confirm your engine model and part number before purchasing to verify proper fitment.
