Has anyone experienced with a shoot-thru-hull transom transducer installation? Seems nice to avoid drilling a hole in the hull, but what happens to the sonar sensitivity? The installation instructions specify that hull can be no more than 5/8" (9.53 mm) thick; any idea on the thickness of a Tripp 33 hull?
