Motor mounts could be replaced with carefully located wood blocks and a porta-power or bottle/scissor jack... Or maybe get some fine-pitch allthread and make yourself a jack of sorts
You would have to re-align shaft/coupler. I would recommend looking at your mounts to see if you can move at all, or if they are maxxed out. You can loosen the coupler bolts, crack the couplers away from each other just a bit, and find out which way your engine needs to go. Say you find .006" gap on stbd and .012 on Port, .000 on lower, and .006" on upper, motor needs to come up some on the front mounts, and go a bit to port. So you move your mounts (symmetrical side to side, so make sure you are going up straight and not twisting) up a few turns on the front mounts (I like to paint or marker one side of the hex nut so I can easily count turns). Check your alignment. Then the real fun begins. Hopefully your mounts have some small side-to side adjustment allowable (maybe the mounting holes are just slightly oblong or have a milled slot). Loosen one side's mount at a time and 'nudge' the motor a little bit, tighten the mounts back down. Check your alignment again. Hopefully this explains some of the reason why getting an engine replaced is so expensive. This is very time consuming work, often performed in the worst possible access areas of a boat.
