Trying to get new exaust bellows in transom and can't get the little screw out of shaft going through exaust holding the shift lever on.There is a shaft coming down through the middle that holds the shift lever, there looks to be a big screw in the top of the shaft and a little one on the side...can't get the little one to break loose. It appears that the shaft will have to come out to get the tool for stretching the bellows in there....does this make sense enough for an answer?
