Key Features:

  • Direct replacement for Yamaha OEM part 63D-11193-A0
  • Manufactured to meet or exceed original equipment specifications
  • Provides a reliable oil-tight seal between the head cover and cylinder head
  • Helps prevent oil leaks and contamination in the upper engine
  • Engineered for durability in demanding marine environments

Sierra International is a leading manufacturer of aftermarket marine engine parts, and each Sierra component is built to meet or exceed the performance of the OEM part it replaces. This head cover gasket is an essential service part for routine top-end engine maintenance or repair on compatible Yamaha 2-stroke outboard engines.

great company to buy from. called them up to find an AFR gauge set. while the one i had my eye one was no longer available, they worked with me to find another one that fit my application and visual requirements. thanks autoplicity!

I've worked easier sites, but overall fairly straitforward. Would buy from again.

Good web purchase

So far so good haven't got it in the mail yet

Easy to search and find parts.

Great experience.

This company is AWESOME! They had an item in stock that I could not get anywhere else and the price and shipping time was super! I will definitely use again.<br>A++++ in my book.....

Great product and was the cheapest I could find. Easy to order and shipping information e-mailed to me the next day.

Very easy shopping experience

Easy site to use and order from. Autoplicity has friendly customer service and also they had the CHEAPEST price on the exhaust tip that I ordered for my truck. I am a very happy customer!!!

nice clean site

Great experience shopping.. will review again upon part arrival. Thanks...

Autoplicity is the best. Always easy, always good prices.

I was in the market for a cargo cover for my new Prius and I searched on line Autoplicity had the best price of all and plus the service was excellent as was the speed in which they promised delivery. While I have not received my shipment as of yet, I'm sure that it will be here as promised if their service is anything like what I have received already.
