Its simple! Place the engine in Neutral, remove the bolts that are visible and nuts. Then remove the upper plug in the case housing that is where the torque tab would be, a plate now on yours probably. Then you maneuver the case down and drop it. There is a copper tube and a small plastic sleeve that the water tube goes into at the top of the crank, and a shift shaft that extends through the down housing. These parts you have to be sure are in place when you stab the crank and drive shaft back together. Just make sure your getting water and it shifts fine after reassembly. BCB
