surely main halyard, dyneema, 10 mm, big boat harken foot block, will do it and save me some money?
Any disasters out there?

I supported my boom with the main halyard attached to the boom end. Then I used the main sheet and one additional 4 part
purchase. I reversed the mainsheet so the clam cleat was at the boom end. I strapped the 4 part purchase around the boom over my
2GM 20 engine through the main
hatch. Likewise with the cleat at the boom end. That way you are pulling down from the cleat which is easier than pulling up. Then once the engine was free I easily lifted it towards the main hatch with the 4 part purchase. I attached the reversed mainsheet to the same point on the
motor. Then lifting with the purchase and pulling with the main sheet; then loosening the purchase a little and then pulling with the mainsheet it was easy to walk the engine towards the
cockpit until it was hanging more or less under the boom end on the mainsheet. So it was now hanging supported by the mainsheet to the boom; the boom end supported by the halyard. Then I removed the 4 part purchase so it wouldn't catch on the
cabin when I swung the
motor. I had already attached my
jib sheets (removed from the jib) to the end of the boom then down to a block on each side
deck towards the stern. I used them to control the swing of the boom otherwise there would be 120 kg swinging out of control. Then standing on the marina finger and using the
jib sheets I swung the boom and motor over and lowered it down into a marina trolley. I did all that easily by myself.
A few points: I had released the
lifelines so as not to catch on the motor. When you swing the motor out the yacht (floating) lists a little so you need to allow a little height for that. It is much easier to have the mainsheet and the purchase
cleats up at the boom end as then you pull down with your body weight.
I did it with the boat in its marina berth. If you were
on the hard you would need to drop it alternately using both purchases and adding a length of
rope to one at a time for the extra height. I think it is easier floating.
I then wheeled the engine in the trolley almost 1 km to the workshop. That was the hardest part. A week later after the motor was reconditioned I reversed the process and reinstalled the motor. A friend came to help then but it was easy by myself and he took photographs. It took almost as long to write this as to do the job.
I believe there is more control doing it this way rather than just on the end of the halyard. I did not need to adjust the halyard / boom height during the operation.
