"I have a 1968 IMP with a 140hp chevy and a sterndrive, It shifts into gear and the moves but if you give it some gas the prop just spins. When I checked the drive unit in foward it turns clockwise with a little click in it. It does not turn counterclockswise. In reverse it turns either way with a click in it. Please help?"

The drive is fine that's the way it should be when turning the prop in gear.
Did you check the condition of the hub in the prop.
The rubber between the sleeve that goes on the prop shaft and the hub of the prop may be wron and letting the prop slip under load.
This will get worse the more you use it if this is the problem.
It's common for this hub to fail after years of use.
