OMC Zephyr 15HP Saildrive
This sail-drive was optional from about 1977-79 on the 25, a few owners may have retrofitted their boats with these as well. A 2-stroke inboard derived from the powerhead of the Evinrude/Johnson 35 HP outboard, detuned to 15 HP. OMC offered a 2-blade aluminum prop, a 3-blade aluminum prop, and a stainless-steel 2-blade folding prop.
