You usually have to tilt the engine a little more than normal to get it out of most hulls when doing it that way but it's very possible. Depends on how difficult it is to align it. 8 bolts to remove the mounts and 4 to remove the engine. It usually goes back together very close anyway if you remember which shims went where. My hull is a pure SOB to realign but I never touch the motor mounts. Additionally, a stripped motor mount is easier to replace than a stripped hull insert.
