Upper rubber motor mount 2-pack for Johnson, Evinrude and OMC outboards from 18 to 35 HP, replacing 0325974, 0778211 and 0303879. The set contains two mounts and two nuts, enough to renew both upper mounts on one engine. It fits 18 HP from 1971-1973, 20 HP from 1986, 1988, 1989, 1991, 1992 and 1996, 25 HP from 1971-1976 and 1979-1983, and 35 HP from 1976 and 1979-1983.
