Had a saildrive
I had a 1969 Columbia 26 MkII that had a 9.5hp OMC saildrive. It's basically a Evinrude/Johnson outboard "thru bolted" the hull. I purchased a Clymer Shop manual for "Evinrude/Johnson 1.5-125 HP 1956-1972" and had all the info I needed. I do not know your year or HP and my engine made no refernce to "Zephyr", check out an outboard manual and see if your engine "looks" like the one in the book. Good Luck, Marc
