Re: 1986 9.9 Yamaha lower unit

question after beating on this lower housing and only getting a screw driver blade between the midsection and the lower unit what else is left I am thinking pulling the lower unit apart unbolting the drive shaft and removing the lower unit that way and then work on the drive shaft inside the crankshaft is this the only way or has someone else gone tru this problem thanks bob

someone told me that to loosen up on the powerhead bolts and run the engine in a barrel that it would loosen up the corrosion while prying on one side of the power head. sounds like it may work does anyone else have any ideas, this must happen often to older salt water motors.
