Transducer Shield and Saver makes sure you have everything you need as far as the “L” bracket, mine needed a spacer so that the transducer was lower, and the transducer mount itself. Any questions and they will answer. I just added a Helix Mega to my boat and had tried to order a new mount online. The order failed. Within 30 minutes I got a call from the company saying they saw where I had tried to place an order and they would help me with what I needed. Fantastic customer service!Yes, I took your advice and sent them an email last night and got a reply today. They want me to double check the JP size.They show a 4″ not a 3″.Im going to do it myself as well. Just need to decide on which Graph & xducer. When you mounted yours, is it slightly lower than then hull step, assuming its a bass boat.
