I can't remember the last time I drank while running my boat.( and no its not cuz I had so much to drink.....) I look at it this way, Lower units are expensive. Rocks and trees break lower units. Alcohol impairs your ability to avoid said rocks and trees. If I hit rocks and trees and have to replace my lower unit, I won't be able to afford to fish or drink for a while. For me its just an either-or thing. Either your in control of the boat, or your drinking in the boat. Not both.
