Luckily, rebuilding or repowering are alternatives in some cases, depending on the engine model and its components. Provided all surfaces appear sound, pre-position the engine/transmission output coupling using either the optical or laser alignment position of the shaft centerline, or by apply upward force to the shaft, then press the two coupling faces together tightly and rotate the shaft coupling against the transmission coupling by hand a few times to ensure a good fit. Ideally, these should be tight and the coupling surfaces parallel. So now you see why when you pay all that money

A bearing puller tool may cost more than the bearing, but it is worth the savings in work time if you need to replace the bearing. Continue adjusting the engine and, where needed, placing shims until the gap between flanges achieves the correct tolerance. Engine alignment is critical for an inboard boat. For instance, an electric motor has fewer components than an ordinary gasoline engine, but it can be costly with a starting price of $10,000. Even if the engine stringers
