I'm getting ready to install my FF and am curious on where to mount the transducer. It will be on my 14ft alum, with a 9.9 merc. the instrustions say to mount it at least 1 ft away from the prop (the cavitation will mess with the trans.) I dont have a foot, not with out risking breaking it off when I trailer the boat. I think I would be ok mounting it closer to the prop, seing that I will be using the FF while anchored, drifting or under power of the trolling motor in the bow. But I am also looking at the possibility of the shoot through option, but the instructions only mention doing this on fiberglass boats. can it be done on an alum boat? Any input is good input, Thanks as always.
