While living in Florida a boat shop replaced the UL18V Champion sparkplugs with ones that actually had an electrode instead of the flat bottom. They told me it was a service bulletin allowing for clearance. When I moved to NY a boat joint replaced my plugs and said I had the wrong ones installed and they never heard of a bulletin with that topic. The boat did seem to start and run better with the alternative plugs and I was wondering what the plug number is. Any help is appreciated! Thanks.
