Hi,
I have a 60hp 1988 merc (ob343140) and have ask this question before but got foggy answer. On the upper end of my driveshaft I have two rubber seals. The bottom one goes on splines up no problem. The top one is shown in the Mercury blowups as narrow dia faceing down. My clymer book shows it narrow dia faceing up. What's your thoughts ?............Jerry
