If you're rebuilding a Johnson or Evinrude outboard in the 25 to 35 horsepower range, you're probably gonna need this.

It's the upper main bearing, a critical internal engine part.

This one is from WSM and is brand new, ready to install.

It replaces a bunch of old part numbers like 010-290, 386481, and 0386481.

It's the genuine replacement for when you're splitting the case and refreshing the powerhead.

Make sure to grab this before you reassemble everything.

It's a small part, but a huge one for engine reliability.
