Which are the correct spark plugs for a 79 rude 25 hp?

[Jquest]

The model number is 25953R. On the coils there is a sticker it's telling me "use L78V", but I go to west marine and they tell me something different ,according to their champion catalog. And my mech. manual is telling me L77J4? And if I go to Champion's website..it's telling me QL82C.<br />Totally confused...

Recommended plug is a QL77JC4 set at .030. Or....L78V or QL82C. I'd run with the QL77JC4...set it at .040 for better low end running.
