Mercruiser 3.0 plugs

[shadowrider]

I have a 98 3.0 mercruiser engine, I pulled the plugs and are not what is recommended on the arrestor plate. Plugs I took out are NGK BPR6EFS The flame arrestor label indicates AC-MR43LTS. I have ordered the latter one. I want to say I read somewhere that the wrong info was put on some flame arrestors. I did not search the manual, I know I will get a good response here. Thanks

That NGK is an alternative plug for the AC, it's even noted in the service manual. Either one will work just fine.

Now that was fast, Thanks Don S.

Re: Mercruiser 3.0 plugs

I've had consistently better luck with the NGKs vs ACs with regard to their ceramic resistors and overall durability. Most on here including Don I believe would lean towards the NGKs.

..but then again.. that's like having another oil discussion for the 5344328744th time.
