anyone got any suggestions for mounting a transducer for a 997c on the transom of a basic aluminum 1654 Fisher boat? I run 2 seperate motors on it...a 9.9 and a 25. Initially I thought mounting it right in the middle would be good but the drain plug is in the middle. I am uncertain about mounting it to one side or the other because i dont want the motor to interfere with the side beam. Somewhere I read to mount it 15" to the left or right of the motor depending on which way your prop turns. Basically Im clueless. Any info would be more than I've gathered at this point.
