I am trying to change my impeller in the water pump and have the lower unit unbolted and it dropped down about a 1/4-3/8" It feels like it is just hanging on the shift rod at the moment. I tried softly tapping with a rubber mallet on the lower unit trying to get it to drop on down. I now think I need to unbolt the shift rod, but am unsure how to go about that. The top of the shift rod has a small bend in it and I am unsure that I will be able to pull it all of the way out of the bottom with the lower unit, assuming that it stays attached to the lower unit. It also appears that the connection of the shift rod to the shift linkages is buried under the bottom of the motor and behind the carbs, and i'm not sure how I would get under there to even get it apart much less back together. Long story short.... Help. I've had this boat and motor about a year now and am enjoying learning how to work on it. Each time I take it apart I learn something new.
