I just read teh omc thread and it made me wonder about changing the gear lube on a merc drive. I drained and filled as directed in manual ( slow and from the bottom) I have reserve gear lube containers that are supposed to provide lube when the drive requires - question - how would I know if an air lock is stopping the automatice flow of oil from the reserve into the drive - how do you know and remover air locks if they exist. Trying to avoid an expensive leason - thanks

I think they kinda work themselves out .I notice that after I change mine and go out a few times the resevoir is a little low and after a few times out it seems to level out . I don't know if you have the pump but if you do , purge the air out of the line before you connect it to the lower unit ( i said "unit" )
