Serial E3605187 model 25R72R put L/u oil in and it leaks some out seating on floor. Did I use wrong oil or should I used some kind of grease (Lubplate 105)? Napa list a seal for this motor (part #18-2005) but the exploded view I have don't show a seal at all on prop shaft just a O-ring. I havn't taken it apart yet. Any suggestions on oil and what I'm getting in to. Thanks
