I have a War Eagle 648vs wi a 40 Yama. i run the LSS2 with my hds7. there is plenty of room for the lss2 ducer but i would put it away from in front of motor, the turbulence trailing off the ducer will cause big motor to cavitate. mine is located about halfway from centerline to side of boat. i reeally like my hds7, at 2mph the screen looks like a video of bottom, i been tracking schools of bream this week in 10fow.
