I tried mounting a transducer in the front hatch of a Mako Kayak with limited results. Where is the best spot to mount the transducer?

So we recommend mounting transducers directly in the water for best results using a deployment arm like YakAttack makes. https://www.basspro.com/shop/en/scotty-kayak-sup-transducer-arm-mount-for-post-mount-with-gear-head-adapter

If you do want to mount it in a hatch in the hull then follow this method. In this video he uses a Jackson kayak to walk through it all, but covers a lot of different hull shapes and designs. That transducer needs to be flat against the hull with no gaps or air pockets. This is a good video.

Hope this helps,
