The Bravo Shift Cable from my engine to my drive was shot. It was the old style with the smaller diameter fitting at the drive. The new cable has a 7/16 inch bore. Mercury says I must use their drill alignment tool to ensure a smooth, straight hole. I think I can get it really really close on my own.

What are your thoughts? If I am a tiny bit off will I screw up my drive?

Thanks!
