That was the reaction of one of our club mechanics when I showed him the picture, but you don't really need one for a Mk I - IV 27 because you can drop a line straight onto the engine, as I described in an earlier post. Also, that device, neat as it is, doesn't solve the balance problem on an A4.
"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 crane.
To remove the cross-piece, you will need a #1 or #2 Robertson head screwdriver; a variation of this is apparently sold in the US 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 try to lift it with the lifting eye alone. 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."
After removing the engine, I put the block-&-tackle aside exactly as it came off the engine. When re-installing, the tackle therefore was set to the right length so that when the engine swung under the cockpit and over its mounts, it was at the correct angle to descend squarely onto the mounts.
One more thing: if the boat is laid up, as mine was for the winter, the hull will change shape significantly because of the absence of the engine's weight. The mounting bolts moved about one inch closer together between late November and May.
