One of those videos towards the bottom is my old boat, always cringed watching my mechanic wail on it with a mallet. But he got it off.This probably isn't going to help but watch it anyway. The last section is the worst case scenario

The driveshaft goes into a blind hole in the end of the crank. When you reassemble you only use a small amount of grease on the splines and not the top of the driveshaft.

If you hit the top of the flywheel with a heavy deadblow is there a chance the shock might carry to that shaft?
I like Kroil as it creeps well, but acetone and ATF might be cheaper.
If you are on FB, check out Yamaha Tech Talk, post the question and watch for an answer from Wayne Shoup, the admin. Good source of Yami info.

Here we go! The only bolts that are in are (4) of the main ones - and they are only halfway in.
Dennis,
if there is a small gap, you may have luck using a bunch of wooden wedges. Whack them in a crisscross pattern and see if you make any progress. I would not hit the drive wheel or crank.

Yup - I have few small small wedges in the front and back. They're not in very far as this point - the front gap is maybe 1/4" or 3/8" while the back gap is about half that.
You can fix the problem maybe and then something else fails your back to not having a boat , Friend recently had shop attempt to remove it then cut the shaft purchased a rebuilt lower unit and that failed during the season .Good luck with your decision !
Anything can happen. But right now I KNOW I'll eventually be facing a problem when the impeller craps out. I'm not worried about "what ifs" Those will get dealt with when/if they happen.

Dennis, have you had any customers ask, just what the hell kind of experiment you're doing, when they see your contraption?
Ha! I did that yesterday (Sunday) when the store was closed. I've since moved it more out of sight
I had trouble a few back, the bushing was stuck on the shaft, Theirs was a lot of build up stopping the shaft from moving . You say the unit comes down a little. Can you fit a small plastic tube up the lower unit inside to spay pb blaster up the hose to hit the bushing?
Dennis, do you have any movement yet?Here we go! The only bolts that are in are (4) of the main ones - and they are only halfway in.
