speed sub finding a prop

I have no experience in rc subs and little in boats. I want to make a sub build soully for speed out of 3" pvc pipe about 16" long not including the nose or rear end. The motor powering it is a 3660 2200kv brushless motor and 95a esc. The recommended is a 40mm x2.189 pitch. That is made a boat on plane so I would assume a smaller prop but im not sure. Also I plan to put a reducer on the rear end that the prop sits inside of with 2 vents to allow water to move in and out and would function like jet drive. This will protect the prop and pressurize the water as It comes out. I need some advice on what kind I would need.
