Hiab. Should be easy to hire one with operator on an hourly rate.

Some great ideas people, much appreciated.
Keep them coming, various bits here that I hadn't thought of!
It all helps...

Shurely at some point, someone in the marina will need a mast stepping or unstepping .. at which point a few of you get together and hire a crane for a day?
There are of course, many ways to jury-rig a lifting beam and similar, it might help to know how heavy the engine is. Lifting a single cylinder Bukh is a different proposition to lifting a 6 cylinder perkins ...

Post #1 gives you the weight. I don't think it's a 6-cyl Perkins.

If the mountain won't come to Mohammed. . .
I would have thought there would be somewhere in Lowestoft with a hoist to hand. Can you not move the boat (using an outboard temporarily rigged up, sails, oar, a dinghy or workboat alongside, a tow, or whatever) to somewhere that can lift the engine for you?
Sorry! I'd forgotten you said it was on the hard. That should make it easier.
What does the marina use to lift boats out with then, that can't be used to lift an engine?

Ah yes, 160kg ... I would just get 4 long lengths of scaffold pole and build an "A" frame on each side, and a run a piece across, with a bit of bracing. If you don't fancy transporting 21' lengths of scaff, just use 10' lengths and an external coupler. All the couplers are available on eBay for very little money.

Why you would want to make it complicated by cobbling together some uncertain structure with all the material and corporal risks is beyond me. Lots of sensible suggestions of forklifts, hiabs and JCBs that would do the job in minutes. The inability of many contributors to read the first post which specifically rules out the boom is another mystery.

Lift out using the boom. This is a big old Volvo engine, too heavy for two of us to lift. Attach the hoist to the centre of the boom and attach as many halyards as possible to the same point. A couple of years ago I watched a man replace a four-cylinder Mercedes engine while afloat alongside a quay using the same method.

I used the boom one time to lift engine out while afloat in a marina. Attached main halyard and topping lift around boom where the chain block located.

That is an important point. if you are going to lift with the boom, you need to ensure the halyards and topping lift all com back to the same point the engine load is applied .. the boom itself does not take any weight, it is merely there to push the halyards away from the mast.

Years ago I use the boom as a cramé jib to remove an old Stuart Turner engine and replace with a Beta Marine engine.
I added the mainsail Halyard to the topping lift for extra strength fixed a block and tackle to the boom at the required point and hauled away. It all worked well with no problems.

The 'usual method' at that marina is apparently to hire a monstrous great 20 ton mobile crane (from two miles away) and pay £300 for thirty minutes work - hence my eagerness to find an alternative.

If there is a nearby small industrial estate , it might be profitable to poke about, knock on a few doors and ask. Don't be put off by an initial negative response as he who insists he can't help might well know someone else who can. I'd be surprised if there isn't a JCB lurking within 5 miles of your boat.

Will a JCB get high enough?
1.7m draft plus topsides = 3+m to cabin top. Engine and hoist slung below bucket/arm another metre. Lift is going to be 4.5m at least to top of jib arm.
Otherwise a good idea, thanks.

The money is getting you a tested, insured crane with load indicator and qualified/experienced operator. And your 30 minutes might be optimistic.

I had a similar problem when I was afloat but with no mast up. Can't remember quite how that came about but I got towed around to the nearest marina and had the engine lift out/in. Then towed back. Towing was done by the boat moored next to me. I wasn't so friendly with him then so he charged me £60 in total.
My reading of the OP is that he still afloat. If so, that might be an option.

Don't think anybody is questioning that? But he needs it twice (unless the new donk is ready and waiting) so £600 plus. That goes a very long way to make a perfectly effective framework to do the job. As above, I could do it for less than £100 in bits and either keep it for next time, or reuse the bits.

Nope, he is on the hard and his boom is not convenient. Notice he counts the draft in the height.

Oh, well. He should wait until he gets launched again, methinks.

One of our club members put a new engine in his boat today using the gantry that we use for moving the boats. He used a cheap ratchet hoist ( from ebay) to lift the engine off the truck with the hoist suspented off the cross beam & got the engine over the guardrail onto the side deck. then re positioned the gantry & swung the engine down the hatch.
Scaffold towers ( hired)each side with a couple of scaffold poles across etc.If you hook it over a scaffold pole with a piece of chain you can slide it sideways( metal to metal) to get it to the hatchway having lifted it up alongside the boat. To stop the pole bending strutit with a bit of 4*2 with a fork cut in it. I buy scaffold poles( thick walled) for about £1 per ft so a 20 ft one would add £20 if you cannot beg one for a day.
You really only need the tower one side . The other side could be 2 short poles fitted as an "A" with a swivel clip & another clip to hold the horizontal one ---or 2 bits of 4*2 bolted & lashed
