Not knowing what kind of TM you have, it's hard to steer you in the right direction. I have an Eagle up front, and I use the pod type on the motor. Just use a stainless steel hose clamp through the slots to secure it to your motor. They make brackets to mount the skimmer type to your TM, but I fish too much wood for them.
