You can contact Express mounts at expressmounts.com. Tell them what fish finder you have and they will set you up with the right mount plate for your fish finder. Then all you have to do is figure out how you want to mount it to your yak. I used a 5 1/4" double socket arm on a 1" ball with a round base. (Pictured above with 3" arm) This will swing in any direction I want it. I mounted it on the inside of the foot well so when I go to load my yak on the truck I can just swing it down out of the way. This one works well for me. But there is lots of ways to configure these mounts.
