Doing a Full Removal 1986 Mercruiser 3.0L 140 hp Engine Question

[1985 Century Mustang]

I'm going to pull my engine and remove it from the boat altogether, I'm redoing my transom.

Question, I'm going to build a platform for the engine lift so I have enough room to clear it from the boat when I pull it. About how high should I build the platform for clearance. It's a basic 2 ton engine hoist. I'm thinking 2 feet high platform should do it. Your thoughts or ideas.

i think when I looked at building a gantry when I did mine I think I needed the lifting point to be around 10 ft maybe higher. So 2ft is probably too low. remember the legs have to go under the boat/engine.

Depends on how high the gunnels are when you are on the trailer. Have seen folks take the wheels off the trailer and put the hubs on a board to get some height reduction.

might be worth seeking if a local wrecker with a boom can do it affordably or just build a gantry out of wood.

I built a gantry, 10' high. That was cutting it close. I had planned on taking it apart when done, but haven't. I know that as soon as I disassemble it I'll need to pull the engine

I did my gantry by measuring the ground to the top of the transom then I added 4 feet for the engine. Remember for the chain pulley you loose about 1 foot . I bought a 1 heavy duty foot chain for the chain pulley to hang on.
There are many gantry designs you don't have to go nuts .

Or take the wheels off the trailer, run the hubs on the concrete. A standard cherry picker should work

The engine came out fine with no platform etc needed. Removed the sterndrive first, then jacked the front bow end of the boat up as high as we could with a service jack and some wood planks. It came out rather easily pulled from the stern area. I used a basic 2 ton engine hoist. Thanks everyone.
