Hi, I`m going to put a 650 engine in a 550 hull,
you need a adapter plate for the conversion, it cost 89,90
the 650 is similair to the 750 ( same motor mount plate)

I`ve got an 750 engine as well that I maybe going to put
in the 550 hull later, as far as I could see the stock 750
exhaust won`t fit in the 550 hull, but I`m not sure?
