Location: Rhinelander, Wisconsin | Mount the ducer on the starboard side.
Make it behave like part of the running bottom, look all the way up the wetted surface of the hull bottom for lift and turning strakes and rivet lines that will dirty up the water coming off the hull and avoid placing the center of the ducer there.
Select an area where clean water is exiting, might take a look back there...carefully...under power.
Follow instructions for a side scan unit.
Use a transducer block on an aluminum boat
Predrill and countersink with a high speed, very sharp drill on a glass boat. Easy, don't force the bit or you will fracture the gel coat.
Some of the aluminum rigs out there have sort of a lipped transom edge, make sure you have the ducer where the water flow is straight back.
Seal all mounting holes in the boat with silicone sealant on the screw and in the drill hole.
Route ducer wire clear of main engine power controls wire if at all possible
Stay away from the outer chines that may be out of the water on a hard turn
Just a few that come to mind.
