Trolling Motor Paint

[EvinFord]

Alright guys, I need some help. I don't post on here much, but I am a long time reader and starting to contribute more lately. I have a problem with my trolling motor on my bass boat. The paint is starting to come off my trolling motor. What is the best way to repair this? Is there a certain kind of paint I need to use and do I need to prime it with anything? Never done a paint repair on the trolling motor before and want to make sure I do it right. Picture is below of my problem.
