I then drilled and tapped the aluminum plate and mounted the transducer on that, exactly in the center. There is enough room that there is ~2″ of clearance between the transducer and the forward edge of the lower unit when the motor is fully down! Best of all – no holes in the transom or in the jackplate! Do be sure to reseal and torque the bolts! I dont have a picture but guess I could take one if need be. C.Yes take a picture of that please, Id like to see that. Sounds like you did a great job! I also like the way tae73 installed his HB, great job! tae73, the screw/bolt that is holding your transducer onto the jackplate. Does that screw go through the transom?FISH ON!
