I am new to owning a boat. I got a used boat with a 2 stroke outboard. I ran it in a local lake the other day and noticed water on the inside of the cowling on the horizontal part of the motor. Its where the cover for the motor attaches. Is this normal? Also I noticed below the power head the outside felt warm or hot to the touch. I do not want to burn it up. It's a 20hp Johnson with tiller control. Thanks for any help.
