Looks like I need to open the motor up. I have an 2005 Tahoe deck with a 5.0 Mercruiser. Short story is impeller went out, motor overheated and it failed a leakdown test miserably. So I need to figure out if its bottom or top end. But I am trying to locate a repair manual to tear down the motor and figure it out. Any help on this would be greatly appreciated
