663-42744-01 – STAY – Yamaha

he 663-42744-01 Yamaha stay is a genuine Yamaha marine bracket used to secure small components on outboard engines and accessories. A “stay” in Yamaha’s parts catalog refers to a bent metal strap or support that holds cables, linkages, panels, or trim pieces in place. Owners often replace stays during service or rebuilds because worn brackets can allow parts to shift or vibrate loose during operation.

This stay fits specific Yamaha models and mounts where the engine design calls for extra support. First, inspect the area where the bracket attaches. Then position the 663-42744-01 Yamaha stay according to the original hardware location. Finally, secure it with the correct fasteners. When installed correctly, this bracket helps keep your outboard’s routing and parts aligned and stable. Many mechanics use stays to organize cables and reduce wear caused by vibration and movement.

Using genuine Yamaha parts like this stay ensures that the shape, bend, and hole pattern match the original part exactly. Aftermarket stays sometimes require modification or do not hold components as firmly. Because marine environments combine water, vibration, and salt exposure, choosing a durable OEM bracket helps your rig last longer and perform better.
