Where to buy core/freeze plugs for OMC cobra 4.3?

[houstonnoob]

As the title stated, where can I buy the core/freeze plugs? Can I buy it from auto part store? I've found 95-97 chevy 1500 4.3L brass freeze plug, will this work on our OMC 4.3? Or I must use the "marine" engine plug?

Thank you for your help. Yes I did use the search botton but unable to find the answer to my question.

If you have not tried Summit Racing (web site), then you could search there. They have marine specific parts. I recently bought a set of core plugs for my 7.4L.

You may have to match the block number, but sometimes they specify the marine engine, etc,

I bought a master marine engine rebuild kit and it came with steel core plugs!!! I called the local O'Rielly's and they had the full brass plug kit for my engine.
