Hey all. I'm new to boat motors and forums, so please bear with me. I have a 1994 evinrude 30 horse E30ELERM and I'm trying to change the impeller... I have read about all I can on this site and I hate to ask the same question... but when I drop the lower unit (4 hidden bolts and 1 nut in the back) it only comes down about 1/2 inch. I've read here that I need to unhook the shift linkage. I just really can't figure out exactly how to do this. I'm starting to wonder if this motor is different than the ones I've been reading about. If anyone could please help me, I would really appreciate it. Thanks in advance. -Bill
