In need of some advise/help I'm No boat mechanic .. we have a 1982 120 Mercruiser I changed the lower unit (new) in forward gear it ratchets CW, it locks CCW but I can turn it with force .. in neutral it spins both ways clicks CW clunks CCW .. in reverse it spins both ways clicks CW and clicks CCW very slightly low noise clicks .. I'm lost as to what to do next .. this problem didn't start until I changed the lower unit .. shift shoe is facing forward those parts are snug no slop
