Well I figure it was time to post an update on the stuck shaft I am dealing with. As some may recall I was given an 86 8 hp johson by TomFL (thanks again 
) that had a drive shaft that was stuck in the crankshaft. I had tried soaking it in with penetrant and suspending the engine upside down by the shaft, hoping gravity would help out. No dice with Mr. Gravity.
I then decided to be a little more proactive in the persuasion deptartment, so I tried using a slide hammer with the 3 jaw attachment. No dice again :-/.
At this point I decided to get a little professional help (I didn't want to booger anything up by being over zealous). I called around to see what the cost would be to have a pro remove it and got the shock of the week... no one wanted to touch it. Every shop I called said it wasn't worth their time or explained that at $90 an hr (I really should have gone to school to be an outboard mechanic in my youth) they would quickly cost more than the poor little moter was worth. (they all mentioned cutting the shaft and buying a new one at $130).
At this point I figured it was time to go a little further with this, so I decided to pull the powerhead yesterday, to gain access to the shaft entering the crankshaft. When I pulled them from the cowling I discovered that the penetrant never even made it to the crankshaft , the joint was bone dry with surface rust. Since then I have been hitting it with penetrant and hanging it by the shaft again. Tomorrow I will take some precautions and apply a little controlled heat to the base of the crankshaft followed with some liquid nitrogen (small amounts) to the driveshaft in the hopes it will cause enough seperation to either allow the shaft to pull free or the penetrant to go deeper sooner.
For those of you who like the pictures... I give you the reason why you should always lube your shaft ;D
