I recently changed the plugs in my 1968 Mercury 200 (20hp). They are champion and I set the gap to .035 instead of .030 because I do trolling with this engine and I do high speed running to . Is this gonna hurt anything. I've already run the engine like this and it seems to run fine but I just wanted to make sure I wasn't hurting anything. I'm a Johnnyrude guy so i'm not qiute used to these Mercs yet.

Thanks, Dan

As long as the plugs are the right heat range and the ign will fire it no problem.
