Has anyone pulled the A4 from thier boat? Does it come out without removal of the cabin woodwork??

yes you can. we did it in a MK1. the mounts were very rusty and a bit of work. we used straps and backs to get the engine to the cabin floor. we then took it over to the mast crane and hoisted it out the companionway hatch, and from there into a wheel barrow. we got a used 3cyl yanmar with 100 hrs for 5 grand and it was a couple of thousand more for the installation. the engine new was 8500 plus tax, so it wasn't a bad deal. the engine is overpowered for the boat, but when we are are backing out of the slip on windy days or powering through 3 meter swells we are happy to have it.

You can remove an A4 without removing the cabinetry. You can probably do a valve job on it by working through the exhaust pipe. But I wouldn't try either. If you remove the wood cross-piece that supports the front of the engine cover, you have much more room to work. Also, you can lift the thing straight out with a crane.
To remove the cross-piece, you will need a #1 or #2 Robertson head screwdriver; a variation of this is apparently sold by Home Despot as a "square drive" screwdriver. There are three or four screws a side and then it just lifts out.
The engine is gearcase-heavy and will bind on the mounting bolts if you just try to lift it with the lifting eye. Do this: Drop a strop three or four feet from the lifting hook to the hoisting eye on top of the block. Then, from the same hook, drop a block and tackle and make it fast at the rear of the gearcase; the block and tackle should make a slight dog-leg as it passes under the cockpit. With everything disconnected on the engine, tighten the block and tackle until the aft end of the engine rises. It's okay if it binds a little bit on the mounting bolts, but not too much. Raise the hook a bit until the front end of the engine binds a bit. Repeat until the engine is off the mounts and hanging free. Remove.

The only thing I would add to the other responses is that when the engine is clear of its mounts, it will have a tendency to kick forward a few inches simply because of the angles involved. If not controlled, which is easy, that could damage some cabinetry. Other than that, my experience from extracting my A-4 for a rebuild two years ago is that it's not particularly challenging. Good luck.

I am just about to do this and as usual find great advice from David W.
A question: the boat is on a trailer on the hard. Has anyone rigged a lifting device over the boat to get the engine up and to the ground? I may just call in the nearby crane operator.
I am thinking of using a basketball to push the engine up off the mounts, along with the strop and transmission tackle David suggests.
To get the cabinet support cross piece off from across the font of the engine, I had to cut through a screw that was inserted into the end grain of the cross piece from inside the cooler compartment. I thought the other end had a similar screw, but turns out it was just very neatly slotted into the cabinet on that side (starboard).
Update: I see in an archived post that David pointed out that cross-piece may provide athwartships support, keeping the port and starboard cabinets apart. I will temporarily replace it.
Update: New information came to light, so no need to pull the engine yet. All is well.

Look at this repowering job - http://www.keithford.net/boatstuff/repower/repower.htm . Looks a bit precarious, but it evidently worked.
I pulled my engine on the water the first time using the club mast jack. Can you move the trailer to the one in the yard you're in (assuming it has one)? When the engine came out for replacement, it was pulled by a strop dropped from the tines of a forklift.
