Close enough?
Gary, I have any O'Day 26 and have the owner's manual. My boat is basically a freshened up version of yours, 1984 hull. The mechanics are all really the same. I've had mine since 86 and do ALL the maintenance and repairs so maybe I can help with specific questions. If you can't find a 25 manual, e-mail me and I'll send you the 26 version.Good sailing, Dave
