Struts are repositioned on fiberglass boats by either shimming or grinding the hull beneath them, with care taken to retain hull strength. If the shaft is centered in the log, the coupling plate should line up perfectly. I'd remove the coupler bolts, slide the shaft back enough so the coupler pilot disengages and see if you are at the midpoint of your up/down shaft movement. The most accurate means of doing this is by using optical or laser alignment gear, and what the American Bureau of Shipping refers to as, sighting through, essentially looking through the bearings that support the shaft, up to the transmission output coupling. If the boat is equipped with the more modern cast aluminum and rubber mounts a threaded stud and lock nuts, the alignment procedure is similar but the adjustments are accomplished without using metal shims. link to How Much Does a Houseboat cost?
