I have a 1972 Bertram with twin 350 starboard side shifts into gear but boat doesn't move ?

I have it out of the water while not running in gear  I can still turn the prop by hand on port side and starboard side.When running the boat it was like I lost the prop the shaft was still spinning from the transmission guess what im asking should I be able to turn  the props by hand while in gear and if so what else could it be its a direct drive port side was pushing the boat while running
