Plug wire popping off coil

The title says it. Had a coil burn up over the winter and since replacing it I've had one wire that keeps popping off. I've adjusted the prong inside that wire and now just zip tied it on. I might just replace the wires since I haven't done that since I've had the boat. Any similar experiences? Any ideas?

Motors is the 5.0 mercruiser EFI. Boat is 2005 Fiesta Vee 300.

Thanks in advance!

    I've seen that happen before. Like you said, adjust the prong on the inside of the wire but also make sure you don't have any dielectric grease on the rubber boot causing it to slip.
