noob question on outdrive for celebrity

[smoothy106]

hello room looking for some help here, not very boat savey and this is my first project. irecently purchased a 1995 celebrity 210, without a motor or outdrive. i am told i have different options on the motor but i need to get a certain outdrive? i have been shopping around and found they are a bit expensive, can someone point me in the right direction as to what the cheapest route to get a motor and a outdrive in there? the boat has all controls and gauges, the guy just pulled the motor and the outdrive. i have also attached a pic of the outdrive hole. maybe someone can identify what motor came stock and what outdrive i should get? thanks ahead of time.
