PRODUCT DETAILS:
Direct replacement red-coded upper center main bearing for Yamaha 4-cylinder 4-stroke outboard engines covering 75, 90, and 115 HP models produced between 2010 and 2017. Yamaha's color-coded bearing system uses different colored bearings (red, red, pink) to achieve precise crankshaft-to-bearing clearances during engine assembly and rebuild. The red bearing is one specific size within this system and must be matched to the corresponding crankshaft journal color marking for proper fit and oil clearance. The upper center main bearing supports the crankshaft between the cylinder pairs in these inline 4-cylinder powerheads and is critical for maintaining crankshaft alignment and proper oil film thickness. Yamaha's F75, F90, and F115 4-stroke outboards represent the core of their mid-range engine lineup and are used extensively in freshwater and saltwater fishing, pontoon, and recreational boating applications. A failing main bearing presents as engine noise, low oil pressure, vibration, or visible crankshaft play during engine inspection. Always verify the red color code matches your crankshaft journal before installation. Confirm your model and part number before purchasing to verify fitment.
