Anybody have any experience removing and installing a core plug on a small outboard. Mines a 56 7.5 Johnson. They don't look like i expected either. They are like a little slug thats concaved.
This is for a core plug on the cylinder head but watching the video they look the same. What do you guys think? Are they the same?
The idea is to flatten it out. That expands it into the cavity. If you go beyond flat (dished the other way) it will get loose again.
