I'm trying to search for "4.3 spark plug" and I've tried forum and posts. Haven't seen 4.3 yet. What do I need to do? I know the info is all over the Mercruiser forum, but I get results from all over the entire forum.
Yes.......... the easiest way to search on iboats is actually to use this in google site:forums.iboats.com before your search term.
The v-bulletin software will not allow you to use a 3 letter search.......such as 4.3 but it you use google and type this into the search box site:forums.iboats.com 4.3 you will get results.
I use AC M43 T plugs, they are made not to ever corrode, and have a large beefy center electrode for a strong spark. This is a guideline, you may need a hotter plug like AC M44 T, or 45 T, or a longer plug I think they are AC M43 TS Depending on conditions? But, you can't go wrong with these.
