My wife's Grandfather bought a boat and decided to try to change the water pump. He says the gear shift was in neutral when he dropped the lower unit. The prop will "free spin" making a clicking noise when turned clockwise. When you spin the prop counter clockwise it spins the shaft and impeller and all that. So maybe I'm wrong but to me it seems like it's in gear which is fine but I don't know if it's in reverse or forward? Thanks for any responses in advance.
