Re: How to Lift an Engine

Not to worry. My second job as a teen was the engine-man for a wrecking yard. You'd be surprised what a sheet metal pan can take.

I use to set an engine up on a wooden bench , on the oil pan, and chain it down. Start it up and grade the motor for sale. Not once did I do enough damage to have it rejected.

Re: How to Lift an Engine

I wish I could say the same but cannot. Remember a 45 horse diesel weighs about 500 lbs with transmission. Remember too at the back of the pan is very close to the crankshaft. At $13,000 a pop these days for an engine, I would do anything I could to sling it from above. There is a reason for those lifting brackets on top.

Re: How to Lift an Engine

@CS -- There is no way to sling it from the top. If there was this thread would not have been started. Thanks for your concern but I know that engines can sit on their oil pans as I have a Mercedes diesel in my garage doing exactly that. I think the key is to distribute the load as much as possible. Thus Del's idea of a formed board to put under the oil pan seems like a good one to me.

My New Yanmar 3YM20 Had to be dropped in through the garage roof opening using the boom as a crane (after removing the garage it made more lengthwise space).

The pan went onto a scaffold board (which had a liberal coating of grease) then the engine was slid along the scaffold board after placing a large timber to act as a fulcrum under the board at the engine bay entrance. (There is no access from the top of the engine bay) I was lucky. I had planned it before I bought the new engine. ) the old engine mountings at the gearbox end/stern were in exactly the same place as the new mountings.

The front mountings were a trifle closer to the end of the bearers. But a template made prior, following the schematic and the dolly it was delivered on with engine mounts fixed to it and removal of the old engine, allowed me to drill the necessary new engine mount holes.

Having temporarily fitted the new mounts free of engine to the engine bearers the engine was slid into the engine bay with the board raising the engine to the necessary height to put it in the bay there was a bit of fiddling because the raw water inlet is slap in front of the engine and in the middle of the entrance so the engine had to be lifted over the top then dropped into position on the mounts. so definitely the oil pan will take the weight (BUT NOT IF YOU DROP IT)

Who I would like to thank for these pictures and who likes sailing but says she does not really like the boat, but is always the first to say what's the wind speed and direction and say "We must go to the port and check the boat is OK" Also when the access is to small she always says "I will do it" and she does.

Re: How to Lift an Engine

Thanks for the pictures Captain Mike. Looks like a good method to get the engine in place. I need to replace the engine on my other boat and will do something similar to what you did. Right now I just need to lift the engine up so I will do that with a scissor jack as Del and a few others have suggested.

Don't forget to spread the load on the hull no square sharp edges please

Re: How to Lift an Engine

Thanks for the tip on the hull I will remember that when I lift the engine this winter.

Re: How to Lift an Engine

I have lifted hundreds of engines of all sorts. Using a scew jack, and a 2X4 on the edge, and corners of the pan one side at a time.......i2f

All I am saying is there is a first time for everything to go wrong. Just take all the precautions you can, Better safe than sorry!
