O'Day 222

We have an O'Day 222 sailboat whichcame equiped with a Johnson Seahorse motor long shaft 8 Hp 65 pounds. The motor has died. We sail on Long Island Sound and have to come into a narrow channel for our dock space. It is prohibited to sail into the channel. We need to have an outboard.
Can I use a much heavier engine such as 4 stroke Honda 8hp weight 117 lbs or Nissan 9.8 hp weight 91.5 lbs without damaging the transom or standard outboard mount on this sailboat?
