The further from the propeller the better without interfering with other functions as EJO pointed out. By the picture it looks like part of the transducer is too deep. It should be tilted slightly to get closer to matching the bottom of the boat. I can also never figure out the use of the Starboard as a "transom saver" for mounting these. Marine Starboard does not seal. Now you have 4 holes instead of two with a material that accepts sealants.

ps: I emailed some pictures of transducer mounting to another member (on my other boat....the Whaler is getting wet next year). If you like I can forward them to you. I am picture challenged but if you can post them....be my guest.
