Looking for impeller o-ring, could use some help please

[wrvond]

1995 7.4L Gen V serial OF437176
​I've searched the Mercury parts catalog with no success. Plenty of gaskets but no o-ring anywhere.
​


Perhaps my impeller housing has been changed to a different year or something.

Mercruiser 25-33465
Supersedes: 25-853220
25-807149
That part comes with the impeller kit sierra 18-73150 or 18- 3237
