    Default oil filter or sparkplug part number on Mercruiser 3.0

    Hey guys, I have a Mercruiser 3.0 in my 2005 Bayliner boat and I can not find an oil filter or sparkplug part number any where.
    I have been searching all day on here, and could not find it in the manual just the oil weight and amount.
    Also what sparkplug gap do yall use.

    Thanks
    Steven

    Stick with the A/C plug's and stay away from the Fram filter especially the one with the sure grip on the bottom it caaused a reduction in oil pressure on my 3.0 LX of 10 psi.
