Trying to change the gear oil on my new 94 mercruiser 3.0. I think I understand how it's suppose to be done but I can't squeeze anymore gear lube in the fill/drain hole. More come's out then goes in. So I filled the rest through the dip stick hole until it came out of the vent hole. Let it sit for a long time and the dip stick level show's full. <br /><br />There seem's to be more of a grind when put into gear instead of the clunk. Haven't taken it out yet but thought I would get some thought's so I don't mess anything up. Thank's for any help!
