I have a 427 Crusader in a 1970 Century Resorter. Over the last two
winters
two 1 3/4" brass plugs have popped out from under the engine block and
were
found sitting in the bilge. Last year I simply pushed them back into
place
and the boat ran fine.

Are these so-called "freeze plugs"? Both winters the boat's been
winterized
as usual. Should I be concerned about these plugs popping out? Should
I
do
something to secure them in place so they won't pop out while the boat
is
running?

Thanks!



Yes, they are "Freeze Plugs". Named because they froze them to install,
not
because they protect the block when water freezes. Go to a good auto
parts
store and buy a couple of new plugs. They are not reusable. They will
run
you a buck or two each. Then you drive them into the hole. Add a small
amout of Permatex sealant on the edges before driving.

Assuming your specious explanation is so..... should he freeze them
first?

Does make them easier to get started. Years ago, when I worked in a garage
in the high school years. we used the CO2 fire extinguisher. Just throw
them in the freezer for an hour or so and the will shrink. What I did when
I raced cars and had to build the engines. They are actually the core plug
holes for the sand cores of casting the block.
