You have to lay it on one side typically assuming this is a small engine???( very important you check which side you need to do it with, some Suzuki I think can be either side but check your manual) and I put a fender under the powerheads to give it some height to help keep oil where it is meant to be.
If it is a big engine then make up a bracket on a pallet to mount it with trim right up so engine head is pointing upwards like it is trimmed up...like this link

Or if it is a one off journey and depending on size, drain oil and put it on an old mattress or cushions.
More info would be good for better advice.
