spark plugs needed

[ronc]

Can anyone tell me offhand what kind of spark plugs are needed for a 1979 Mercruiser 470 ?? My boat is currently in storage, and I would like to get spark plugs to install myself. Thanks for any help!

If a parts store can't tell you. Take out one of the old plugs and have an autoparts store cross referance it.
