Outdrive seals & maintenance

Found water mixed in my outdrive gear oil when I went to change it, the oil is milky in color. Looking for an illustrated parts breakdown of the outdrive and maintenance/service manual. Would appreciate link to get illustrated parts breakdown and purchase maintenance/service tech manual. Want to rebuild it and service it myself from whatever is causing the problem. I am pretty handy with auto tools, just need the parts breakdown and tech manual to rebuild with new seals, bearings, etc.
