If I were you, I'd go to the local auto parts house and purchase petcocks
instead of plugs. This will make winterizing much easier and the petcocks
are not expensive.

I am looking for new drain plugs (3 of them) they all appear the same and
look to be 3/8" diameter thread and are a 7/16" head... they are for a '77
mercruiser 140HP 181 engine. I am looking for atleast a part number for
them or something simular or if they are something easy to get somewhere
other then my local marine shop that wants $14ea for them and wont give me
a
part number

Thanks in advance.
