ELTO speedster/quad or big Johnson or Lockwood chief would all be good period-correct motors. I personally would put a Lockwood chief on it as that is one of my favorite motors I do not own that would put your boat on a decent plane, and has some really good styling, but put whatever you like. A later po-15 would also look nice if the boat can handle the wieght and you do not need it period-correct. The link I posted is of a boat that I assume to be somewhat similar with a Lockwood chief on it. If both the motor and boat were restored, it would probably look really nice.
