There is nothing specific to the engine as far as I am aware - mine is craned out regularly. As the weight of the engine is on bearers in the hull, you have to make sure the hull is adequately supported by the trailer, but that is to do with the boat rather than the engine. Never ever run the engine or even turn it over while out of the water unless connected with a hose, your water impeller will disintegrate in seconds. If you have an external speedo impeller, make sure the lift strops don't damage it, and when you put the boat back in make sure all bungs and seacocks are closed - other than that there is nothing more really!I am taking a inboard diesel engined boat out of the water and on to a trailer for transportation.what are the do,s and dont,s, where the engine is concerned.
e.g - what needs doing to the engine before and after?
sorry for my ignorance.
