Yamaha - Key, woodruff - 90280-05001-00 CLNCRE and select 15–25hp Mercury/Mariner 2-strokeYamaha Woodruff Key Flywheel & Shaft Alignment 90280 05001 00 Overview This woodruff key is one of those parts that keeps everything lined up behind the scenes. It holds your flywheel and shaft in the exact position they need to stay in so timing doesnt drift.
