The Sierra 18-3841-2 is a precision-engineered head gasket designed specifically for Johnson and Evinrude 2-cylinder outboard motors.

  • Precision-machined to perfectly match head and block surfaces for reliable sealing
  • Premium quality construction for extended service life
  • Meets or exceeds OEM specifications for guaranteed performance
  • Direct replacement for Johnson/Evinrude OEM part number 203130
  • Also interchangeable with GLM 34010

Fast

Shipping was lightning fast! Received order as described and in great condition. Expectations exceeded!

Amazing! I scoured the internet for a few days for a hard to find battery. I found it here for a few hundred dollars less & I received it the next day! I was blown away! I will use THMotorsports as a resource from here on! Thank you!

During a regular boating season I usually damage one aluminum prop per year . Once again, I needed to replace my prop on a 50hp outboard that I use during fishing and deer hunting on the Missouri River. In past years I have had to allow time for the new prop to arrive. Not this time! The people at Boatplicity got the prop to me the very next day! And I paid the lowest price I have ever paid for the prop. I now have Boatplicity on my favorites list and will definitely use them for all my boating needs.

It is quick shipping and pack well, the most important that price is 25% off than other market price
