When I did it:
I bought an engine crane at an auto parts store ($250), installed it over the engine hatch, stripped the engines, then called a guy with a truck mounted HIAB crane. The boat was in an accessible position on the parking lot of the marina, so he could position his truck where he wanted it. He was so good with the HIAB that my small crane was unnecessary. The Stb engine (furthest from the door on the port side) came up with transmission still attached, by swinging forward as it was lifted, then blocking and lowering it to the cabin sole, removing the transmission, turning 90 degrees and lifting it through the doorway. Port engine, as it was closer to the door, didn't have so much swing room so the trans had to come off in the bilge. Otherwise same process. The doorway is 27" wide. Without Heat Exch, exhaust riser, alt, the old engines were able to slip through with 1/4" to spare. The new were tighter, as they have Aftercoolers, so a piece of cardboard against the varnish on both sides took the squeeze and no damage was done.
Find a guy that is good with a HIAB. Ask around at marine mechanics. Someone will know of one.
