Check out NGK's website, there's a "part finder" for Marine Engines. If you have your engine serial number, it might help. It's usually located on a sticker on the flame arrestor, or on the top of the engine.

They make thousands of models of plugs, so make sure you pick the right one for your engine. I searched and found the right model for my boat, headed to West Marine and picked up a set, and once spring gets here, I'll install them. I would assume if the large chain Marine stores are selling NGK's, they must be pretty good, or at least a suitable replacement.
