Restrictor Plate O-Ring Pack (4)

The Restrictor Plate O-Ring Pack (4) from KING RACING PRODUCTS is an essential maintenance component for Yamaha outboard motors that rely on restrictor plate seals for proper fuel and cooling system integrity. After years running boats on the water, any serious angler or boater knows that o-ring degradation is one of the most common culprits behind fuel delivery issues and performance loss. This four-pack replacement set ensures you have spares on hand when aging seals begin to fail, preventing unexpected downtime during critical fishing trips or recreational outings.

Restrictor plate o-rings function as compression seals that maintain proper pressure and flow control within Yamaha's fuel and cooling subsystems. These durable elastomer components are engineered to withstand salt spray, UV exposure, and thermal cycling—the exact environmental stressors that deteriorate seals during extended marine operation. The four-ring configuration in this pack means you can replace worn seals across multiple restrictor plates or maintain a full inventory for seasonal maintenance cycles, reducing the likelihood of mid-season mechanical failure and associated repair costs.

This replacement pack is ideal for Yamaha outboard owners who perform their own preventive maintenance or professional technicians servicing marine engines in the field. Installation is straightforward—remove the old o-rings, clean the seating surfaces, and install fresh rings to restore a reliable seal. Whether you run a single-engine fishing rig or manage multiple outboards, keeping the Restrictor Plate O-Ring Pack (4) in your maintenance kit ensures you're never stranded by a seal failure. Compatible with Yamaha restrictor plate assemblies across multiple engine models and years.
