"I just got a 9.9 model # 92h
"I just got a 9.9 model # 92hb made between 1970-1973 This might be a dumb question, When checking and changing the lower unit oil there are two plugs upper and lower, The upper say's vent by it, the lower say's fill. Do you really fill by the lower one. Can't be much oil in it if you fill by the lower plug, it's down near the bottom of the lower unit.I thought It might be a drain plug for the oil? What is the upper vent one for then? If you know could you let me know the correct procedure.
Thankss Dan"
