hi this is my first post .. I have two mowers and one is blown but its in a lot better shape it is 917.270671 16hp the other is 917.270821 19.5hp just wondering if the bigger engine will bolt up and the wiring hook ups ? thanks for any help
Hello, being that they are both Craftsman, you have a basic easy swap. The engines are no different in bolt pattern and wiring should be plug and play. You should swap muffler and all too to keep it simple.
