78 115hp Evinrude coil and plug wire

Could these cause problems? What type of problems?

Yes, they can cause problems.

My guess would be ignition problems.

That cracked plug boot will cause a path for the spark to travel along the outside of the spark plug. That orange wire on the coil doesn't look very healthy either. Replace the coil.

Agree with the above !!
