Lifting the engine...

[yachtorion]

I've unexpectedly bought a new engine...

The boat is high on a trailer with the rig off.

Any ideas for lifting the old engine out of the cabin and down to the ground, and then the new one back up and in?

So far all I've come up with is a cheap engine hoist tied down to the chainplates...

I got the yard to give a hand with their fork-lift. Cost a few beer tokens but well worth it.

 

[yachtorion]

I should have said - the boat is in a self storage yard, no friendly forklifts or cranes near by...

Its only a small engine, so i'd rig a well braced and located scaffolding A frame over the cockpit with a block and tackle at the peak, and once the engine is hoisted high, move the boat temporarily from underneath if its on a trailer. Reverse the process to lift the new one in

Your Yanmar is small enough and light enough to lift out by hand, using a beam across the companionway and mainsheet to lift it out into the cockpit and then two people and a sling to swing it over the side. Useful to lower in two stages - I used an oil drum and lift into the boot of the car. Same thing in reverse, although your new engine will be heavier than the old so a little more muscle power needed. Alternatively build a gantry out of scaffold poles outside the beam of the boat.

Rope round a roof beam, then block and tackle on the end of it?

Literally this very time last week.

Lorry with a HIAB crane is how I would do it.

That's more or less what we did with Kindred Spirit. The A frame was more of a goal-post shape, and we used an electric winch rather than a tackle, but very much the same idea. Also we couldn't move the boat and had to lower the engine over the side, but if the OP can tow the trailer out from under the frame then that will be much easier.

Because of the boot lid we couldn't use the winch to drop the engine in the back of my VW Polo, but two of us were able to lift the 2GM20 in by hand.

Talk to your local builders merchant (or a driver) to see how much they would charge when a truck not being used or in your area with deliveries.

Sadly can't put the mast up - the self storage yard is next to a power station and there are a lot of wires overheard.

The HIAB thing would be difficult because of how cramped the yard is. Though that's how the old engine got back in recently (It came out for a rewire and some sensor replacements).

The a-frame thing could be a possibility but again this yard is cramped. Unfortunately moving the boat isn't easy either.

I am quite liking the engine hoist idea... I could use it to get the engine out of the car easily, lift the hoist (fraction of engine weight) on to deck, tie it down to chainplates etc, use it as an arm over the side of the boat to get the engine up high enough (with a block and tackle) to swing the engine inboard, then setup for lowering the engine down the companionway with the hoist.

Might look into hoist rental.

Cherry picker might be a good choice too - anyone know what it costs to rent one?

Thanks all..

It`s weight is 71kg

Peyton knows how things get done in boatyards..

I know someone in our club selling

Ex NHS hydraulic patient hoist safe lifting weight 127 kilo will lift a lot more.
I have one at home great for lifting engines in and out only £15.00

I'll PM his number if you want. It's in Carlisle, (I think)

When I re-engined a cobra a few years ago I changed a yanmar yse12 for a volvo 2020the Yanmar was a heavy lump and we had it craned out. However the volvo was considerably lighter and we slid it up a ladder nearly onto the cockpit combing and the with it still on the ladder we lifted up the floor end of the ladder to the horizontal and slid it across to the other combing so that the ladder formed a bridge. Then with a couple of substantial ropes we tied it to a thick piece of wood and the two of us then lifted it of the ladder and suspended it over the companionway.It was then an easy job to slowley lower the engine down to the cabin floor. I can remember making a small table out of scrap wood at the same height as the engine bearers so that it could be slid easily into position.
As for lifting the old engine out, if you remove some of the ancilleries, starter motor,alternator and possibly the gearbox it should be the light enough to lift out.

And don't forget to remove the flywheel before you lift it. It is heavy and removing it saves effort.

 

[sailorman]

might be tricky with a 1GM10

Having done the same operation with a 1GM in a Twister, I,would stick to low-tech solutions. A strong piece of wood across the companion way will give you enough height to lift the engine into the cockpit using the main sheet. From there, with two of you present, construct a 'way' of wood to allow you to first lift the engine onto the cockpit bench and then onto the coaming edge. To get the engine to floor level, use a plank on a ladder (as has been said above) to slide the engine down, using the main sheet again to support the weight. Don't let anyone stand underneath things, obviously. It is a reasonably manageable lump; I can lift mine complete with gearbox from the floor into the boot of an estate car without the aid of a third shredded wheat.

Just waffling on but may be of interest. Our local Flying Doctor Service had a problem getting patients on a stretcher from the ground in through the door of a small aircraft then rotated. They occasionally had 150 kg to lift. They used main sheet traveller track supported on structrure and the plane roof. The traveller car then had a tackle attached so that patient could be lifted to the necessary height then rolled along the track into place.
Now if OP had a mansheet track or even a steel girder that can have a rolling car attached this may be mounted on A fram or similar supports to allow safe raising and moving of engines. food for thought I hope. good luck olewill (and be careful)
