I pulled my 1974 140 hp engine to take care of some leaks and to repair the stripped out front engine mounts. I'm also in the process of a restoration and am taking the boat to a shop for fiberglass work and to get most everything replaced in the gimbal housing (all bellows, lower shift cable and gimbal bearing). I noticed gear oil in the u-joint tube, so I think I also need a seal in the upper end of the lower unit. So,I was going to reinstall the unit and trailer it to the shop without the engine, which will make it easier to repair the engine mount holes. Does it create any problems for the lower unit to be hanging on the transom without the engine?
