"Charlie,
How are you going
"Charlie,
How are you going to push the drive off from the inside of the boat?
There are not a lot of ways to get a drive off short of cutting it, no matter how much thought you put into it. I've been making a living doing this for 30 years and I've already put a lot of thought into it and if I didn't know, without a doubt, that this may be the only answer, I would not have suggested it. Been there, done that.
The shaft and coupler are much less expensive to replace than the upper housing and gimble assembly, and since they are already junk, what is the problem.
If you can explain to me how to push the drive off from the inside the boat I'll reconsider my position.
Rick"
