I resealed all the motor bolts today. Did one at a time and used 3M 4200. Put the lower bolts in from the outside as recommended by Mercury site. This way sealer is pushed inward into the hull. We generously slathered the bolts up and pushed them so that the excess would fill any voids on the motor mounting bracket.
I didn't put sealant in the holes first and now am second guessing myself. Should I be?
