right plugs for a '1994 70-horse Force

[plane]

My "Force by Mercury Marine" is getting hard to start, and I suspect the plugs...right now there are 2 NGK's and one Champion in it. Unfortunately, I'm not at the boat, so I don't know what numbers are in it. From the '94 sales brochure, I know the engine has CD ignition...and other sources on the internet lead me to suspect that calls for a special plug. My local dealer says it takes an NGK BUHW, but some online sources suggest that a BUZHW is the one for CD ignition. According to the title, the engine serial number is OEO 77061. What's the right plug? Thanks.
