Product Details

The Sierra 18-3186 is a replacement impeller wear plate designed for Yamaha outboard engine water pump systems. This hard-wearing plate sits beneath the impeller inside the water pump housing, providing a smooth, durable surface that protects the pump assembly and helps maintain consistent water flow for proper engine cooling.

Key Features:

  • Durable construction engineered to withstand continuous marine use
  • Non-corrosive finish resists the harsh saltwater and freshwater environments
  • Hard-wearing surface extends the service life of the impeller and pump assembly
  • Meets or exceeds OEM specifications for a direct, reliable fit
  • Sold as a single wear plate

OEM Interchange:

  • Yamaha Outboard: 63D-44323-00-00

The Sierra 18-3186 impeller plate is also included as a component in Sierra water pump repair kits such as the 18-3415. Sierra is a trusted aftermarket manufacturer with decades of experience producing marine engine and drive components that meet or exceed original equipment standards. Replace this wear plate during routine impeller service to ensure optimal water pump performance and prevent engine overheating.

Great transaction. Like the part that they let you know if it's in stock. I was surprised at the FAST shipping of my order. The web site suggested it would be delivered on Friday after a Friday order was placed. It actually was delivered on Wednesday, two days prior to the estimated delivery time. Very well pleases with this company and will do business with them again when the need arrives.

First time and liked it.

My experience has been a real pleasure.

Only place I was able to find this product
