Product Details

The Sierra 18-7469 is a precision-engineered replacement o-ring designed for Yamaha outboard motors. This marine-grade seal provides reliable protection against water and oil leaks in lower unit applications.

Key Features:

  • Direct replacement for Yamaha OEM part number 64E-43869-00-00
  • Marine-grade rubber compound resists saltwater, oil, and temperature extremes
  • Precision-molded to OEM specifications for proper fit and seal
  • Designed for lower unit gearcase applications
  • Quality aftermarket alternative from Sierra, a trusted name in marine parts

This o-ring is an essential component for maintaining the integrity of your Yamaha outboard's lower unit during routine maintenance or gearcase service. Replacing worn o-rings helps prevent costly damage from water intrusion and lubricant loss.

straightforward

Easy to order and quick shipping. Was the best price.

quick and efficient

Great! My part got here BEFORE the estimated delivery date! Now I may be able to complete my project in time! THANKS!!!

It was easy to order and the truck bed extender we bought was the lowest price we could find! However, the shipping charge was higher than what was posted on the comparison sight. Nevertheless, it still came in under the next highest price from a different vendor.

good service

Quick and Easy

Easy

I had a hard time getting to where I wanted but once there it was OK.

Fast shipping, good communication, a pleasure to do business with. I would definitely buy from again.

Quick, cheap & dirty!
