I got a new boat. Had the dealer install the humminbird electronics. Helix mega 9 SI G2N. Got it out on the water today to start breaking in the motor. While I was at idle we play with the Helix. Here is the problem. The mechanic installed the SI transducer in the wrong spot and the motor lower unit is blocking the beam going to the left. What can I tell them to do to make it right. They screwed it up and they are going to fix it. Just need to know what to do. It is on a Lund impact 1875.
