Re: Outdrive shaft seized in flywheel drive
Ok, according to my 87 service manual, it's a 984542 drive, 984757 transom mount, and depending on thru hull exhaust/power steering etc, the engine should be 504AMFTC(ARY) or 504APFTC(ARY)
Of course someone over the years could have made changes to all of it. and it may have other stuff in there.
Bottom line, it's Cobra. Did you buy it or are you going to buy it...( I guess if you're changing the engine you have already bought it )
Someone else that has had this problem will have to take it from here. That drive obviously has not been off in many years. I am thinking that I would put the rear engine mount bolts back in and set the engine back onto the mounts.
remove the drive nuts (6) and the rear trim cyl thru bolt and support it with a hoist and use a chain hoist or strap to pull the drive off.
If it's REALLY corroded you may break something pulling the drive off. The upper gear housing was not really designed to handle a severe pull force on the yoke/U-joints etc.
But there's a few people here that have had this exact problem and can tell you how they did it.

by the way,
I did a little search of this forum (using the key words "coupler" stuck" "rust" )

That guy had to cut the yoke. I don't envy you.
The outdrive is an 87 omc outdrive and the engine is an 87 chevy 305
