350 mag spark plug gap?
I'm changing my plugs tomorrow and was surprised to not find what the AC plugs should be gapped at. Also how many qts of oil does it hold?
Thanks for any help.

I prefer MR43T AC plugs because they have a large diameter center electrode (us cruiser guys hate changing plugs), but the R43TS is a good choice because of the extended tip. If yours runs better at .040-,045, by all means run it that way. Basically, it's finding what works best for your engine.

Using AC MR43LTS. That's what was suggested by the Mercruiser parts dealer. .045 is the correct gap. I called Mercury this morning. Now I get to regap them all.
