GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
For what is worth BUHW-2 is the equivalent of L78V
The nearest NGK equivalent of QL77JC4 is BZ7HS-10

BR7HS-10 is not an acceptable alternative in an OMC CDI system despite the fact you'll often find it quoted as an equivalent of QL77JC4
