Original part # 171260 NLA. I have dropped the skeg to have it repaired and would like to replace this grommet when I reassemble. Not sure if the old one was the original or a replacement. It is sloppy in the housing and just seems to float in the hole. I’ll have my son make one with his 3D printer. It appears not to fill the hole depth wise as it would block the port on the bottom side. I assume it should fit snug on the pipe and snug in the hole. Other than height any advice to help a lot of trail and error?
