It would depend on how your boats stringers are set up......
It would be an awful lot of work, in any case....
If ya need the extra power, it would be far easier to just move to another boat......
Preferably one with a Merc or Volvo drive......
Welcome to iboats, BTW.....
Anything is possible, but with how much work and at what cost?? It would be far easier and economical to buy another boat. And as Haut said, stay away from OMC!!
