A little update: I got tired of waiting on the magic potion to do its thing so I pulled the heads and looked inside. Pretty much what I thought  rusted beyond belief.  Took the pan loose and removed the rod caps. Tried to remove the sleeve and piston together. No such luck.  So tomorrow we will pull the motor.  Here is where my question comes in.  How to you uncouple the hydrapower from the transmission? It looks to be a coupler like a pto but I am un sure.  We are down to the motor mount bolts and the transmission coupling but unsure from here.  Help would be great thanks again.
