    155hp in a 185hp hull?

    I have a 03 GTX 185hp hull with a bad engine that I may rebuild. I also have a 155hp na engine complete. What issues would I run into to install the 155 into this hull? I have the electronics from the 155.
    I do understand that I can change the pistons and pto cover, flywheel, install super charger and make the 155 into a 185.
    Just seeing what would be involved in dropping the 155 into it as it sits.

    155 motor is NOT the same as a 185
    the 155 also has higher compression and wimpy pistons
    but everything should be interchangeable
