You just need to find a way to mount it in a fairly level way. My boat has an aluminum cap at the point of the bow, it has a curve to it so I got some rubber spacers from the hardware store to provide the proper mounting height to allow it to sit level. I had to add spacers for 3 of the 4 mounting holes.
You may need to make a mounting plate to bolt to your boat and then mount your motor to it.
Let me know if you need details in how I did mine and I can take some pictures to show it to you.

Edit: this is for a foot operated trolling motor. If it's a hand operated motor you shouldn't need any special mount.
