h23 brackets,
For anyone who owns an h23 and has not looked inside real closely where out board mount bolts thru you may want to inspect it, in time the bolts loosen and they get retightened, in the process they tend over the years to dig into the fiberglass I reglassed mine and put a metal backing plate there ,additionally make sure that area is sealed really good because if not water gets between the motor mount and transom and can weep into the bolt holes, when I did mine I filled completely and redrilled, good luck Mike Bacome
